  • Arrangement for tape winding machines for the compensation of a unilateral tape tension
    Patent number: 4700905
    Abstract: An arrangement for tape winding machines for the compensation of a unilateral tape tension of tapes to be wound which can be easily attached to a winding machine or integrated into the same. This is achieved in that the arrangement consists of a compensating roller (6) provided between a transfer roller (4) and a fixedly arranged delivery edge or a brake guide roller (3), as viewed in the direction of movement of the tape. The compensating roller (6) is freely movably supported in a guidance (10, 10') in such a manner that the axis of rotation (7) of the compensating roller (6) can tilt from its position parallel to the plane formed between the transfer roller (4) and the delivery edge, respectively, guide roller (3) and is able to subject the tape (1) to a torsional force (twisting) corresponding to the unilateral tape tension.
