BATT-DRAFTER Mod. ST4-200

This machine is particularly suitable for stretching layers of tape coming from folding machines, up to a maximum weight of 500 g/m2. Stretching is carried out in a controlled and adjustable manner while the machine is in operation.

The rollers are partially equipped with special seals designed to comb the fibres, making them parallel. The machine consists of two side frames housing the cylinder guides and sliding supports. The machine works with 3 pairs of thick rollers, 100 mm in diameter.

The lower cylinders are fixed, while the upper ones are housed on bronze guides. The vertical adjustment of the upper cylinders is carried out by means of pneumatic jacks; the final distance is adjusted by means of a mobile limit switch using a manual wheel with micrometric screws.

The first two pairs of cylinders are covered with a rigid sheath, while the third pair is smooth. Each pair of cylinders is driven by a gear motor, and all pairs of cylinders are connected to each other by means of toothed wheels.

The distance between each pair of cylinders is 120 mm. If material becomes stuck between the cylinders, the limit switches are activated, immediately stopping the machine.
