Haul Off Belts - Extrusion Puller

Haul-Off-Belt

ZZR offers a diverse selection of haul-off belts manufactured on Timing, Poly-V, Flat or Banded-V bases.

Polyurethane haul-off belts demonstrate exceptional performance in terms of minimal wear and resistance to chemicals.
V-section bases are self-centering, removing the necessity for additional belt guides. Different non-marking cover textures provide a range of solutions to meet your process needs effectively.

Haul Off (Caterpillar) Belts are potential replacement belts for cable, wire feeding, cutting, stripping and assembly machines such as komax, schleuniger, artos, eubanks, megomat, metzner, ramatech, carpenter, eraser, spectrum and tekuwa. 

We can build haul off belts with special coatings and processing according to customers’ requirements.

Description of Haul Off Belts

“Haul-offs” are mechanisms consisting of parallel belts driven by pulleys. They are designed to engage both sides of products in progress. Typically, rollers apply appropriate pressure to enable the belts to securely grip and pull the products with controlled force.

They operate in pairs and are individually crafted with a cover layer tailored to match the shape and texture of the product being transported.

A segmented coating, referred to as a “caterpillar,” enhances the belt’s flexibility, enabling it to accommodate smaller pulleys more effectively.

A cord or fabric reinforcement layer is chosen to withstand the pulling force exerted by the belts, while the base layer is tailored to match the profiles of pressure rollers and drive pulleys.

Solutions can be achieved in the profile and plastic extrusion industry and in the cable, pipe and wire industry.

Cable drawing belts are employed in two types of equipment: 

  • Caterpillar machines
  • Capstan machines

FAQ

What is haul off extrusion ?

A Haul-off is engineered to consistently pull the profiles produced during the extrusion process. ZZR provides two varieties of haul-offs: belt and caterpillar.

The double belt haul-off, used in PVC profile extrusion lines, is important for pulling profiles. By employing various rubber pads on caterpillars, the haul-off can accommodate profiles of different shapes. The device also features an adjustable draw-off speed tailored to the extrusion process.

What are the different types of haul-off ?

Haul-offs are available in various types, such as Belt, Double Caterpillar and Multiple Caterpillar. Each tailored for specific product diameters and production speeds. Belt haul-offs are well-suited for cables, pipes and wires with smaller diameters, typically ranging from 10mm to 32mm, especially in scenarios requiring high-speed production.

Alternatively, bigger diameter pipes require the use of multiple caterpillar haul-offs or double caterpillar haul-offs. Selecting the right haul-off unit for your specific production line is vital to prevent potential issues and ensure seamless production.
