Abstract
A machine has a frame, a rotatable configuration of two partners in the form of a bobbin cylinder and a bobbin resting on the bobbin cylinder for winding and unwinding yarn or tape-like material, one of the partners being firmly attached to the frame, and a carrier being movable relative to the one partner for supporting the other of the partners. An apparatus for controlling at least one of contact pressure and relative motion of the partners of the rotatable configuration includes an electromechanical power proportional or current proportional torque adjuster connected to the carrier, and a control device connected to the adjuster for controlling the contact pressure with the adjuster to provide slip between the partners in ribbon zones.
