Abstract
A system for winding a cross-wound bobbin has a rotatably supported tube holder that is intended to receive a tube. The yarn guide element that serves the purpose of shogging the yarn moves in the direction parallel to the axis of rotation of the tube and is made to execute the oscillating reciprocating motion with the aid of a work cylinder. The work cylinder has the advantage that for braking the kinetic energy at the turning point of the yarn guide element, no additional external energy must be applied. It suffices for the applicable cylindrical chamber to be blocked off. Moreover, the gas compressed in the process can be used to accelerate the piston in the opposite direction. The stored braking energy also can be used simultaneously as acceleration energy. Since in the creation of a cross-wound bobbin many thousand such changes of direction occur, the energy savings are substantial.
