Product Description
The SPS Series Pipe Coiler is a purpose-built automatic pipe winding machine engineered by Chenxing Machinery for the precision coiling and packaging of flexible plastic pipes, hoses, and tubular profiles directly downstream of extrusion production lines. Covering a pipe diameter range from φ16 mm to φ110 mm across three standard models — SPS-32 (Double Station), SPS-63 (Double Station), and SPS-110 (Single Station) — this series accommodates everything from small-bore medical tubing and communication cables to large-diameter industrial hoses and cable sheathing.
At the core of the SPS Series is a moment motor-driven constant-tension winding system that maintains uniform coil tightness regardless of the progressively increasing coil diameter during winding. Combined with a frequency inverter for stepless speed regulation from 0.5 to 20 m/min, the machine delivers consistent, repeatable coil quality batch after batch. The double station configuration on SPS-32 and SPS-63 models enables non-stop coil changeover — while one station completes winding, the operator unloads a finished coil from the other station and mounts a fresh spool, maximizing production throughput. The single station SPS-110 is optimized for large-diameter, low-speed, high-precision coiling where coil consistency takes priority over changeover speed.
Designed for seamless integration into complete plastic pipe manufacturing lines, the SPS Series can operate in synchronized mode with upstream caterpillar haul-off machines, dust-free pipe cutters, and pipe belling machines to form a fully automated pipe production and packaging cell. Alternatively, the machine can operate in stand-alone mode with a manual feed. The modular steel frame construction, PLC/HMI touchscreen control, and CE & ISO certifications make the SPS Series a reliable, export-ready solution for pipe manufacturers worldwide.
The double station configuration is the high-throughput workhorse of the SPS Series. Two independent winding stations share a common frame, drive system, and control architecture, allowing one station to continue winding while the other is being unloaded and re-spooled. This non-stop production capability eliminates the downtime penalty associated with single-station coilers, translating to significantly higher effective output — particularly valuable for high-speed extrusion lines running 24/7.
The SPS-32 targets small-diameter flexible pipes (φ16–φ32 mm) at winding speeds up to 20 m/min, producing coils with inner diameters from 480 to 800 mm and outer diameters up to 1,280 mm. It is ideally paired with high-output small-pipe extrusion lines producing PVC braided hose, PE water pipe, and pneumatic tubing. The SPS-63 handles medium-diameter pipes (φ32–φ63 mm) at the same 1–20 m/min speed range, but accommodates larger coils — inner diameters from 600 to 1,200 mm and outer diameters up to 2,000 mm — making it the go-to choice for medium-bore industrial hose, cable conduit, and irrigation pipe applications.
Both double station models share a common moment motor architecture (10 N·M for SPS-32, 25 N·M for SPS-63) and can be field-configured for various coil widths (230–370 mm for SPS-32; 360–560 mm for SPS-63). The dual-station design is particularly advantageous when integrated with a pipe extrusion line where continuous output demands zero-gap downstream handling.
The SPS-110 single station configuration is purpose-designed for large-diameter, low-speed coiling where precision and coil integrity outweigh raw throughput. Covering the φ63–φ110 mm pipe diameter range at winding speeds of 0.5–5 m/min, this model is built around a high-torque 40 N·M moment motor — the most powerful in the SPS family — to maintain consistent tension on heavy-gauge, stiff-walled industrial hoses and large cable sheathing that smaller motors cannot handle.
The SPS-110 produces exceptionally large coils: inner diameters from 2,500 to 3,500 mm with a generous 700 mm coil width, enabling fewer coil changes per production shift and longer uninterrupted extrusion runs. This model is the preferred choice for manufacturers of large-bore PVC suction hose, PE agricultural pipe, industrial ducting, and heavy cable conduits where the coil dimensions and tension requirements exceed the capabilities of double station alternatives.

Contact our engineering team for application-specific coil dimension estimates. All models support field-adjustable coil width within their respective ranges via mechanical stopper repositioning.
The defining technical advantage of the SPS Series is its moment motor-based tension control architecture. Unlike conventional AC induction motors that require complex closed-loop feedback systems with tension sensors, dancer arms, and PID controllers, a moment motor inherently maintains constant output torque across its entire speed range — including near-stall conditions. This means that as the coil diameter progressively increases during winding (from an empty spool to a full coil), the motor automatically delivers the exact torque required to maintain uniform winding tension without any external regulation.
The practical benefit is threefold: first, every layer of pipe on every coil is wound at the same tightness, eliminating the "loose inner layers, tight outer layers" problem common with speed-regulated winding; second, the system is mechanically simpler with fewer components that can fail or require calibration; and third, tension consistency directly improves downstream logistics — tightly wound coils are more compact, stack more stably during transport, and unwind more predictably at the end user's facility. The three torque ratings (10 N·M, 25 N·M, 40 N·M) are carefully matched to the pipe diameter ranges, ensuring sufficient gripping force without crushing or deforming the pipe wall.
All SPS Series models are equipped with a variable frequency drive (VFD) that provides true stepless speed control across the full operating range. For SPS-32 and SPS-63, the range spans 1–20 m/min; for the SPS-110 handling heavier large-diameter pipes, the range is 0.5–5 m/min — deliberately slower to allow precise tension buildup and layer alignment on oversized coils.
The VFD serves two critical production functions. First, it enables real-time line speed synchronization: when the SPS coiler is integrated downstream of an extrusion line with a caterpillar haul-off machine, the winding speed can be slaved to the haul-off speed via a simple analog signal or digital communication protocol, ensuring the coiler never pulls ahead of (stretching the pipe) or lags behind (creating slack loops) the extrusion output. Second, the stepless adjustment allows operators to dial in the optimal winding speed for different pipe materials and wall thicknesses — a stiff PE pipe can be wound faster than a soft, thin-walled medical PVC tube that requires gentler handling — without the discrete speed jumps inherent in gearbox or pulley-based speed change mechanisms.
On the SPS-32 and SPS-63 double station models, the two winding stations operate independently under a shared control architecture but with separate moment motor drives, expandable chucks, and guide roller assemblies. This architecture enables hot-swappable coil changeover: while Station A is actively winding, the operator can safely unload a completed coil from Station B, inspect the finished coil, and mount a fresh empty spool — all without stopping or slowing the winding process on Station A.
Once Station A reaches its preset coil diameter or pipe length, the PLC executes an automated changeover sequence: Station A decelerates and stops, the guide roller assembly redirects the incoming pipe stream to Station B, and Station B accelerates to the preset winding speed. The entire transition completes in seconds, with no pipe cutting, re-threading, or production line stoppage required. For high-speed extrusion lines producing small-diameter pipe at 15–20 m/min, this non-stop capability can increase effective daily output by 15–25% compared to single-station alternatives that require a full stop for every coil change.
All SPS Series models feature expandable mandrel chucks on the winding shafts — a mechanical design that uses radially expanding segments to grip the inner surface of the coil core. Unlike fixed-diameter shaft designs that require precisely matched core sizes or adapter sleeves for every core variation, the expandable chuck accommodates a range of core inner diameters within its expansion stroke, simplifying core inventory management and reducing changeover time between different core specifications.
The chuck segments are pneumatically or mechanically actuated (depending on model configuration) and provide uniform radial clamping force around the entire core circumference. This prevents the core from slipping on the shaft during winding start-up — a common failure mode with simple set-screw or single-point clamping designs when the moment motor delivers its full 10–40 N·M starting torque. The expandable design also facilitates rapid core removal after winding: releasing the clamping pressure collapses the segments, allowing the finished coil to slide off the shaft with minimal resistance.
The pipe entry path on every SPS Series model incorporates a multi-roller guide assembly positioned between the incoming pipe feed and the winding station. This assembly serves three engineering functions: lateral alignment — the rollers constrain the pipe's approach angle to the winding spool, preventing diagonal layering that produces lopsided, unstable coils; tension equalization — by forcing the pipe through a defined serpentine path before reaching the winding station, any residual tension fluctuations from upstream equipment are damped, delivering a more uniform tension profile to the winding point; and twist prevention — the roller arrangement counteracts the natural tendency of round pipe to rotate or twist during coiling, particularly problematic with ribbed or corrugated hose profiles.
The guide rollers are mounted on adjustable brackets, allowing operators to fine-tune the entry geometry for different pipe diameters and stiffness characteristics. For applications involving extremely soft or thin-walled tubing (such as medical-grade silicone catheter tubing), optional low-friction roller coatings can be specified to minimize surface marking.
The SPS Series is governed by a programmable logic controller (PLC) paired with a human-machine interface (HMI) touchscreen, providing an intuitive yet powerful control environment. Operators configure winding parameters — target coil diameter or pipe length, winding speed, tension profile, and station selection (double station models) — through the touchscreen interface, with real-time feedback displayed for motor current, winding speed, accumulated pipe length, and coil diameter estimation.
The PLC architecture supports several automation scenarios beyond basic parameter control. For integrated production lines, the controller can accept external signals from upstream equipment such as the dust-free pipe cutter to coordinate cut-to-length operations with coiling. Built-in safety interlocks monitor motor overload conditions, broken-pipe detection (via tension anomaly sensing), and emergency stop status, triggering controlled deceleration and shutdown sequences when faults are detected. The HMI also maintains a production log — coil count, total pipe length wound, average cycle time — valuable for OEE (Overall Equipment Effectiveness) tracking and shift handover reporting.
Every SPS Series pipe coiler is manufactured under Chenxing Machinery's ISO 9001:2015 certified quality management system and carries CE marking in compliance with applicable European Union directives (Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and Electromagnetic Compatibility Directive 2014/30/EU). This dual certification provides documented assurance to international buyers that the machine meets recognized standards for design safety, manufacturing consistency, and electromagnetic compatibility.
For importers and distributors in regulated markets — particularly the European Union, United Kingdom, Middle East, and Southeast Asia — CE and ISO certification simplifies customs clearance, reduces the administrative burden of technical file documentation, and demonstrates due diligence in supplier qualification. The certification package includes a Declaration of Conformity, risk assessment documentation, and electrical safety test reports, all available upon request during the quotation process.
The SPS Series is built on a heavy-gauge welded steel frame with integrated vibration-damping mounts and leveling feet. The modular design philosophy segregates the frame into three distinct functional zones: the winding station(s) at the front, the drive and transmission compartment in the center, and the electrical control cabinet at the rear. This segregation simplifies maintenance access — drive belts, bearings, and chuck mechanisms can be serviced without disturbing the electrical enclosure, and vice versa — and improves thermal management by separating heat-generating components (motor, VFD) from temperature-sensitive electronics (PLC, HMI).
The open-frame design at the winding stations provides 360-degree operator access for coil loading and unloading, while the enclosed drive compartment protects the transmission components from dust and debris common in plastic processing environments where plastic crushers, plastic grinding machines, and high-speed mixers generate airborne particulate. Optional stainless steel cladding is available for food-grade or medical tubing applications requiring heightened cleanliness standards.
The SPS Series implements a structured five-stage coiling process, from pipe infeed to finished coil removal, designed for continuous operation with minimal operator intervention.
Stage 1 — Pipe Alignment and Infeed: Flexible pipe exits the upstream extrusion line or is manually fed into the guide roller assembly. The multi-roller alignment system straightens the pipe approach path and centers it relative to the winding station. When integrated with a pipe extrusion line, the coiler's speed reference signal is synchronized with the caterpillar haul-off speed to maintain consistent tension in the buffer zone between the haul-off and the coiler.
Stage 2 — Clamping and Initial Wind: The operator (or an automated clamping mechanism on higher-spec configurations) secures the pipe leading end to the expandable mandrel chuck. The PLC initiates a soft-start ramp — the moment motor gradually increases torque over a configurable duration — to prevent sudden jerking that could stretch or snap the pipe. Initial winding proceeds at reduced speed until two to three complete layers are formed, establishing a stable base for subsequent high-speed winding.
Stage 3 — Constant-Tension Winding: Once the base layers are established, the VFD ramps the motor to the operator-set winding speed (1–20 m/min for SPS-32/63; 0.5–5 m/min for SPS-110). The moment motor maintains its preset torque output as the effective coil radius grows, ensuring every successive pipe layer is wound at identical tension. The guide roller assembly continuously tracks the coil face position and adjusts its lateral position to maintain even layer distribution across the full coil width.
Stage 4 — Automatic Changeover or Stop: When the coil reaches its preset diameter (detected by a limit sensor or calculated from accumulated pipe length), the PLC initiates a controlled deceleration. On double station models (SPS-32, SPS-63), the guide assembly redirects the incoming pipe flow to the standby station, which then starts its own winding cycle — all without interrupting the upstream pipe feed. On the single station SPS-110, the machine completes its deceleration and stops, signaling the operator to remove the finished coil.
Stage 5 — Coil Removal and Re-spooling: The operator releases the expandable chuck clamping pressure, and the finished coil slides off the mandrel. A fresh empty spool is mounted, the chuck is re-engaged, and the cycle repeats. The entire unload-and-reload sequence on double station models occurs on the idle station while the other station continues winding — the operator never works against a running machine.
Safety Interlocks: Throughout all stages, the PLC continuously monitors motor current (overload detection), pipe tension (broken-pipe detection via sudden tension drop), and emergency stop circuit integrity. Any fault condition triggers an immediate controlled stop. A physical emergency stop button on the main control panel provides redundant hardwired shutdown independent of the PLC.
The SPS Series hose coiler serves a broad spectrum of flexible pipe and tube coiling applications across multiple industries:
PVC/PE Plastic Pipe & Hose: The primary application — coiling of PVC braided hose, PE water pipe, garden hose, pneumatic tubing, and agricultural irrigation pipe directly after extrusion. The winding tension control is particularly critical for thin-wall PVC hose, where excessive tension can cause ovality or collapse, while insufficient tension produces loose, unstable coils.
Cable & Conduit Sheathing: Flexible cable conduits, corrugated electrical sheathing, and communication cable protective tubing benefit from the SPS Series' consistent coiling for neat spooling onto cable drums or coil-form packaging. The expandable chuck accommodates the larger-core cable drums commonly used in the electrical industry.
Medical & Pharmaceutical Tubing: Small-diameter medical-grade tubing — IV lines, catheter tubing, peristaltic pump tubing, and respiratory circuit hose — requires gentle, precision coiling without surface marking or kinking. The SPS-32 with its fine speed control and low-torque moment motor is well-suited for these sensitive applications.
Industrial Hose & Ducting: Large-diameter industrial suction/discharge hose, ventilation ducting, and chemical transfer hose (φ63–φ110 mm) are the domain of the SPS-110, whose 40 N·M torque output handles heavy, stiff-walled hoses that smaller coilers cannot manage. The 700 mm coil width accommodates flat-profile hoses that require wider coil faces.
Downstream Packaging Integration: Beyond standalone use, the SPS Series integrates into complete downstream packaging lines that include automatic screw feeders for raw material handling, plastic pelletizers for recycling edge trim and scrap back into the production stream, and ZSQ vibrating screens for material classification in compounding operations upstream of the extrusion line.
Manufacturers producing PVC WPC foam board extrusion lines or PVC hot-cutting pelletizing lines also benefit from the SPS coiler for handling the flexible pipe outputs that complement their rigid product portfolios. Companies running SMF series disc grinding pulverizers for PVC powder preparation often pair them with extrusion lines that feed directly into SPS coilers for finished pipe packaging. For temperature-sensitive coiling applications — where warm pipe exiting the extruder must be cooled before winding to prevent deformation — our SML series air-cooled chillers provide the necessary process cooling upstream of the coiling station.
Proven Extrusion Line Integration: Unlike generic winding equipment that requires extensive customization to interface with extrusion outputs, Chenxing Machinery coilers are designed from the ground up as extrusion-line downstream equipment. Speed synchronization with caterpillar haul-off machines, signal handshaking with pipe cutting machines, and mechanical compatibility with standard extrusion line layouts are built in, not retrofitted.
Application-Specific Engineering Support: Every SPS Series quotation is preceded by an engineering review of the customer's pipe specifications — material, diameter, wall thickness, stiffness, target coil dimensions, and line speed. Our team recommends the optimal model, configures chuck dimensions, fine-tunes the tension range, and validates coil quality parameters before the machine enters production. This consultative approach minimizes the risk of specifying inadequate or over-specified equipment.
Global After-Sales Network: Chenxing Machinery provides remote commissioning support via video call, on-site installation and training by factory engineers (optional, quoted separately), and a comprehensive spare parts program with DHL/FedEx express shipping for critical components. Maintenance documentation, electrical schematics, and PLC program backups are delivered with every machine.
Comprehensive Product Ecosystem: The SPS coiler is one component in Chenxing Machinery's complete plastic processing equipment portfolio. Customers sourcing multiple machines — plastic crushers, high-speed mixers, SMF pulverizers, pipe belling machines, and complete extrusion solutions — benefit from single-supplier accountability, consolidated logistics, and coordinated technical support.
A moment motor is an inherently torque-regulated machine — it maintains nearly constant torque from near-zero RPM to its rated speed without requiring external feedback loops, tension sensors, or PID controllers. In a pipe coiler application, as the coil diameter grows from a 480 mm empty spool to a 1,280 mm full coil (SPS-32), the moment motor automatically adjusts its current draw to deliver the same winding tension on every layer without any control system intervention. A conventional AC motor, by contrast, would require a closed-loop system with a dancer arm or load cell feeding tension data to a VFD that continuously adjusts motor torque — adding complexity, cost, maintenance points, and potential failure modes. The moment motor approach is mechanically simpler, more robust in dusty plastic processing environments, and typically more cost-effective for the torque ranges required in pipe winding.
Yes, the SPS Series handles corrugated and ribbed hose profiles effectively. The expandable mandrel chuck grips the core, not the pipe surface, so external pipe texture does not affect clamping. The guide roller assembly can be adjusted to accommodate the slightly different entry behavior of corrugated hose versus smooth pipe — corrugated profiles tend to have slightly higher bending stiffness in one axis, which the roller arrangement compensates for. For heavily corrugated or spiral-reinforced hoses with significant surface irregularity, Chenxing Machinery can specify wider roller spacing and optional roller surface treatments to prevent the corrugation peaks from catching or snagging during high-speed winding. We recommend providing a hose sample during the quotation process so our engineering team can validate winding behavior and recommend any application-specific adjustments.
Synchronization is achieved through speed reference signal sharing between the caterpillar haul-off machine and the SPS coiler. The haul-off machine outputs an analog 0–10V or 4–20mA signal proportional to its line speed; this signal is fed into the SPS coiler's VFD as the speed setpoint. The coiler's frequency inverter then adjusts the moment motor speed to match, maintaining a constant buffer loop of pipe between the haul-off and the coiler. In more advanced configurations, digital communication protocols (RS-485 Modbus, Profibus, or EtherNet/IP) enable bidirectional data exchange — the coiler can signal "coil nearly full, prepare for changeover" to the upstream PLC, which can then temporarily reduce extrusion speed if needed. For cut-to-length operations, the dust-free pipe cutter provides the cut trigger, and the coiler completes the current coil before the next pipe section arrives.
Routine maintenance is minimal and consists primarily of: (a) monthly inspection and greasing of the chuck expansion mechanism and guide roller bearings using standard NLGI #2 lithium grease; (b) quarterly belt tension check and adjustment on the motor-to-shaft drive transmission; (c) semi-annual electrical cabinet inspection — tightening of terminal connections, verification of VFD cooling fan operation, and cleaning of cabinet ventilation filters (particularly important in environments with airborne PVC powder or plastic grinding machine dust); and (d) annual replacement of VFD cooling fans and inspection of the moment motor's carbon brushes (if applicable — some configurations use brushless moment motors). With proper maintenance, the SPS Series has a design service life exceeding 15 years in continuous three-shift operation. The modular frame design means major components — motor, VFD, PLC, chuck assembly — can be individually replaced without scrapping the entire machine.
The hose winding machine is fully suitable for coiling flexible electrical cables, communication cables, and wire products within its diameter and tension specifications. The key consideration for cable applications is tension control — cables, particularly multi-conductor or shielded types, can be damaged by excessive winding tension that crushes the internal conductor arrangement or stretches the outer jacket. The moment motor's constant-torque characteristic is actually advantageous here: once the desired tension is set, it remains stable regardless of coil diameter, unlike speed-regulated winding where tension can spike as the coil builds up. For cable applications requiring ultra-low tension (such as thin coaxial or fiber optic cables), Chenxing Machinery can configure a reduced-torque moment motor variant. We recommend providing cable samples for tension validation during the pre-sales engineering review.
All SPS Series models operate on standard three-phase industrial power: 380V 50Hz (standard), with 220V 60Hz and 415V / 50Hz configurations available upon request. Power consumption varies by model — the SPS-32 draws approximately 3–4 kW during peak winding, the SPS-63 approximately 5–7 kW, and the SPS-110 approximately 8–10 kW. Factory floor space requirements are compact: SPS-32 occupies roughly 2.5 m × 2.0 m, SPS-63 approximately 3.0 m × 2.5 m, and SPS-110 approximately 3.5 m × 3.0 m — plus operator access clearance of at least 1.0 m on all sides. The machine is shipped as a pre-assembled, pre-wired unit requiring only leveling, power connection, and compressed air supply (6 bar, for pneumatic chuck actuation if equipped). Detailed foundation drawings and utility connection specifications are provided with every quotation package.
Yes, flat and oval-profile hoses — commonly used in agricultural drip irrigation (lay-flat hose) and firefighting (collapsible discharge hose) — can be coiled on the SPS Series with appropriate setup. The key adjustment is the guide roller configuration: flat hoses must approach the winding spool at a controlled angle to prevent folding or creasing, and the roller assembly's spacing and alignment are adjusted accordingly. The coil width parameter becomes particularly important for flat hose — wider coils (up to the model's maximum) prevent the edges of the flat hose from protruding beyond the coil face. For lay-flat hose that is wound in the collapsed state, the winding tension must be carefully dialed to avoid stretching the hose material during winding; the SPS Series' moment motor and VFD combination provides the fine control granularity needed for these sensitive applications. As with all non-standard applications, we strongly recommend providing a hose sample for winding trials during the engineering review phase.
