Take-off system

View all 9 images

Take-off system for the production of sheet thickness ranging from 0.18 – 3.0 mm. The following types of calanders are available:

  • Vertical calanders
  • Inclinded (45º) calanders
  • Horizontal calanders

The calander diameter ranges from Ø 300 – 600 mm according to the required capacity of the extrusion line.
The calander width ranges from 500 – 2500 mm.

The total line speed is adjustable with one hand wheel. With an offset value it is possible to adjust the speed of the top and bottom roller within +/- 5% of the line speed. The maximum tension in the sheet can be set on the operator panel.

The rollers are double shell polishing rollers, outer shell hardened, with cooling spiral for efficient and uniform heat transfer and cooling over the full cylinder length and are hard chrome plated. The rollers are supported with heavy-duty, self-aligning bearings for accurate, smooth and trouble-free running and all 3 rollers are separately driven by servo-drives and AC-motors.

Rubber-roll unit
The rubber-rol unit is placed after the calander and is fitted with a knives system for cutting the sidetrims and lane cutting. The sidetrims go to an attached side-trim granulator or side-trim winder.

The knives is a Stanley knives system with double knife holders for fast and easy replacing of the knives during running of the line.

As option a roller knives system can be provided for cutting thick PET sheet.


The temperature regulation of the rollers is done my means of a microprocessor controlled temperature regulation for each chromium roller by means of water pumps.

Nip adjustment system
For nip adjustment between the rollers a “continuously adjustable gap adjustment calibration system” is available. The gap/nip between the rollers is accurately and finely adjustable with wedges and has a digital read-out function. Therefore this system is highly advisable in cases where the gap/nip needs to be adjusted regularly.
