HAUL-OFFS FOR SMOOTH-WALL PIPE – M SERIES

EXTRUTEX M Series Pipe Haul-Offs

EXTRUTEX M Series haul-offs are designed for the controlled and continuous pulling of smooth-wall pipes manufactured from ABS, PVC, PE, PP and other thermoplastic materials. The series is suitable for modern pipe extrusion lines where stable traction, accurate line speed and reliable pipe handling are essential for maintaining consistent production quality.

The M Series can be configured for a wide range of pipe diameters, from compact small-diameter applications to large-diameter pipes up to 3,500 mm. Different caterpillar configurations, drive arrangements and contact lengths can be selected according to pipe diameter, material, wall thickness, extrusion speed and production requirements.

For complex multi-extruder or multi-layer applications, EXTRUTEX can also provide the Combopull configuration, combining up to four independently controlled haul-off units. Each traction unit can operate at its own precisely controlled speed, allowing different pulling requirements to be managed within the same extrusion system.

Available M Series Sizes

EXTRUTEX M Series haul-offs are available in configurations covering:

63 mm | 160 mm | 250 mm | 450 mm | 630 mm | 800 mm | 1,200 mm | 3,500 mm

The actual working range of each machine depends on the selected caterpillar width, pipe diameter, pipe material, wall thickness and extrusion-line configuration.

KEY FEATURES AND ADVANTAGES

1. Independent Traction Drive System

Each caterpillar is powered through an independent drive system, providing accurate control of the pulling force and line speed.

The drive system is designed to maintain stable traction throughout continuous production, helping to prevent sudden changes in pulling speed that could influence pipe dimensions, wall thickness and surface quality.

Independent drive control also allows the machine to respond effectively to different pipe materials and production conditions while reducing unnecessary mechanical transmission components.

2. High-Grip Caterpillar Traction

The M Series uses long-contact caterpillar tracks to provide a large gripping area around the pipe.

The extended contact surface distributes the pulling force over a larger section of the pipe instead of concentrating the traction in a small area. This is particularly important for:

• Large-diameter pipes

• Thin-wall pipes

• Flexible PE and PP pipes

• High-speed PVC production

• Heavy-wall industrial pipes

• Large-diameter extrusion applications

The result is stable and continuous pipe movement from the extrusion die toward the downstream equipment.

3. Optimized Caterpillar Geometry

The caterpillar assembly is designed with a controlled contact profile that follows the pipe surface while maintaining reliable traction.

The optimized geometry helps reduce unnecessary deformation of the caterpillar belts and minimizes excessive mechanical stress during continuous operation.

This design contributes to:

• Longer belt service life

• Stable pipe contact

• Reduced belt deformation

• Consistent pulling performance

• Lower maintenance requirements

4. Adjustable Upper Traction Unit

The upper caterpillar assembly is designed for controlled adjustment according to the pipe diameter.

The adjustable structure allows the operator to establish the required contact pressure without applying excessive force to the pipe.

Correct pressure control is particularly important for soft or flexible thermoplastic materials where excessive compression could deform the pipe.

The system therefore provides a controlled balance between:

traction force + pipe protection + dimensional stability

5. Motorized Caterpillar Positioning

The lower traction assembly can be positioned according to the required pipe diameter.

Motorized adjustment allows faster and more convenient machine setup when changing between different pipe sizes.

This is especially useful on production lines manufacturing multiple pipe diameters, reducing setup time and making diameter changes more efficient.

The positioning system can be integrated with the machine control system according to the required automation level.

6. Non-Marking Traction Pads

The caterpillar tracks are equipped with specially selected rubber or elastomer traction pads designed for reliable grip while minimizing surface marking.

The contact material can be selected according to the pipe application and thermoplastic material.

This is particularly important for pipes where surface appearance, printing quality, coating adhesion or dimensional accuracy must be maintained.

The traction surface provides a controlled combination of:

• Grip

• Pressure distribution

• Surface protection

• Wear resistance

• Long operating life

PRECISE LINE-SPEED CONTROL

Accurate haul-off speed is essential in pipe extrusion because the pulling speed directly influences the final dimensions and wall thickness of the pipe.

EXTRUTEX M Series systems are designed to provide stable and precisely controlled linear movement.

The haul-off can be synchronized with the extrusion line so that the pulling speed remains consistent during continuous production.

Depending on the complete line configuration, the control system can coordinate:

Extruder → Die Head → Cooling → Haul-Off → Cutting → Stacking

This creates a synchronized downstream process and helps maintain consistent production conditions.

COMBOPULL – MULTI-HAUL-OFF CONFIGURATION

For specialized extrusion systems, EXTRUTEX offers the Combopull concept.

The Combopull configuration allows up to four haul-off units to operate within one extrusion line.

Each haul-off can be independently controlled, including its own traction speed. This makes the system suitable for applications where different extrusion sections require different pulling conditions.

The four traction units can be configured according to the line architecture and product requirements.

Combopull advantages

• Up to four independently controlled haul-off units

• Individual speed adjustment

• Flexible multi-extruder line configuration

• Suitable for complex pipe extrusion systems

• Synchronization with extrusion-line control

• Accurate traction management

• Suitable for multi-layer and co-extrusion applications

The individual speed control allows EXTRUTEX engineers to configure the pulling system according to the actual process requirements rather than using a single fixed traction speed for the complete line.

APPLICATIONS

LARGE-DIAMETER PIPE PRODUCTION

EXTRUTEX M Series technology extends from small-diameter pipe applications to large-diameter extrusion systems up to 3,500 mm.

Large pipes require substantially higher traction capability and careful pressure distribution because of their greater weight, diameter and wall thickness.

For these applications, EXTRUTEX can engineer the haul-off according to:

• Pipe diameter

• Pipe wall thickness

• Pipe weight

• Material

• Extrusion output

• Line speed

• Required traction force

• Cooling-line configuration

• Downstream equipment

• Production environment

The large-diameter versions can be integrated with heavy-duty downstream equipment for industrial and infrastructure pipe production.

EXTRUTEX ENGINEERING CONFIGURATION

Rather than offering one fixed haul-off design for every application, EXTRUTEX can configure the M Series according to the complete extrusion line.

The machine configuration can include different:

• Caterpillar dimensions

• Traction lengths

• Drive capacities

• Rubber pad specifications

• Pipe-contact arrangements

• Adjustment systems

• Speed ranges

• Control configurations

• Automation interfaces

This allows the haul-off to be matched to the extrusion process rather than simply selected according to nominal pipe diameter.

OPERATOR-FRIENDLY DESIGN

The M Series is designed for practical operation in industrial extrusion environments.

Motorized positioning reduces manual setup work, while controlled caterpillar pressure helps operators establish stable pipe traction.

The haul-off can be integrated into the central extrusion-line control system, allowing important operating parameters to be monitored and adjusted from the main HMI.

Depending on the complete project specification, EXTRUTEX can provide:

• Digital speed control

• Motorized positioning

• Pressure adjustment

• HMI operation

• Line-speed synchronization

• Emergency-stop integration

• Production-line communication

• Automatic recipe parameters

• Customized PLC control

RELIABLE TRACTION FOR CONTINUOUS PRODUCTION

A haul-off is one of the most important downstream components in a pipe extrusion line. Even when the extruder and die are operating correctly, unstable traction can influence the final pipe dimensions and production consistency.

The EXTRUTEX M Series is engineered to provide controlled and continuous pipe movement from the cooling section toward the cutting or winding equipment.

The combination of independent drive control, extended caterpillar contact, adjustable positioning and non-marking traction surfaces provides a stable solution for both standard and demanding pipe extrusion applications.

M SERIES SIZE RANGE

Final machine dimensions, caterpillar configuration, traction force and drive specifications are selected according to the customer’s pipe and production requirements.

ENGINEERED FOR COMPLETE DOWNSTREAM SYSTEMS

EXTRUTEX can integrate M Series haul-offs with complete downstream equipment for thermoplastic pipe extrusion, including:

Vacuum Calibration Tanks → Cooling Tanks → Haul-Offs → Cutting Machines → Chamfering Units → Pipe Stacking Systems

For larger pipe systems, the haul-off can be engineered together with the complete downstream arrangement to ensure suitable material handling and synchronized production.

EXTRUTEX supplies customized downstream solutions for PE, PP, PPR, PEX, PVC, UPVC, CPVC, ABS and other thermoplastic pipe applications.
