Extrusion line haul-off pullStream

for pipe extrusion lines

Short description
pullStream haul-off systems for PO and PVC pipe extrusion: belt haul-offs and multiple caterpillar haul-offs with integrated touch-screen control. Configurable to fit into extrusion lines; customized versions and special adaptations (e.g., FDC – fast dimension change) available.

Your Advantages

• Belts and caterpillars driven individually by 3-phase motors, optional as servo drives
• High haul-off forces due to high motor torque and pressure cylinders
• High synchronization accuracy with coordinated drive motors
• Back pressure control for thin-walled pipes
• Electric adjustment of all caterpillars to pipe diameter
• Upper caterpillars with pendulum support and pneumatic contact pressure
• Integrated control via touch screen

For pipes from 16 to 800 mm

• Multiple caterpillar haul-offs with 3, 4 or 6 caterpillars fitted with V-shaped rubber studs
• Bottom caterpillars manually or electrically adjustable
• Start-up aid mounted on haul-off to save space and synchronize via pilot frequency

For pipes from 800 mm upwards

• Multiple caterpillar haul-offs (6–14 caterpillars) with V-shaped rubber studs
• Electrically adjustable caterpillars at top and bottom
• Start-up aids up to 180 kN tractive force, synchronized with haul-off via pilot frequency
• Deflection rollers and rope guides of start-up aids mounted on a tilting frame at the outlet end

For small diameters up to 125 mm (especially composite, microduct and drip irrigation)

• Belt haul-offs with Poly-V belts for smooth running
• Extrusion speeds up to 300 m/min
• Extrusion height adjustable via hand wheel; fixed stop electrically adjustable
• Easy access for belt change due to quick belt change system
• Lateral pipe guides for high-speed extrusion
• Pivotable top support to compensate for twisting of the pipe during extrusion
