Abstract
The fabric take-off device comprises a fabric take-off roller mounted to be movable transversely of its longitudinal axis and two associated rod-shaped fabric guide elements which are mounted on fixed axes for supplying the fabric to the take-off roller and for taking the fabric away from the roller. The fabric tension causes the take-off roller to be pressed against the two guide elements due to the movable mounting of the roller. This contact-pressure force increases automatically as the cloth tension increases. A very reliable fabric take-off is obtained without slipping of the fabric on the take-off roller. To avoid damage to the fabric, the take-off roller need not have a rough surface nor need any pins, but may have a relatively smooth surface made, for example, of plastics.
