pullStream
Belt and caterpillar haul-offs for PO and PVC pipe extrusion
Integrated control via touch screen
Depending on the application and pipe size, pullStream belt or caterpillar haul-offs are available, which are controlled via an integrated touch screen and fit perfectly into the line. Production of customized versions is also possible. Specially adapted versions can be supplied for special applications such as FDC (fast dimension change).
Your Advantages:
- Robust design
- Belts and caterpillars driven individually by 3-phase motors, optionally 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 with V-shaped rubber studs
Bottom caterpillars manually/electrically adjustable
Start-up aid mounted on haul-off for saving space and synchronizing via pilot frequency
For pipes from 800 mm upwards
- Multiple caterpillar haul-offs (6-14) 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 on tilting frame at the outlet end
For small diameters up to 125 mm, especially composite, micro duct 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 and 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
