Abstract: A reel for winding and unwinding rolled strip into a reel shaft with a reel drum axially movable in a stationary reel housing. A positioning drive formed by a non-rotatable but axially movable piston-cylinder unit is utilized for spreading apart the segments of the reel drum. The segments are maintained in the spread-apart position by the force of a spring. A displacement drive formed by a piston-cylinder unit is used for axially moving the reel shaft. This reel makes it unnecessary to axially move the reel housing including positioning drives, drive motor, coupling and gear assembly by means of a displacement drive. Also, the provision of a rotary pressure supply for spreading the segments is unnecessary.

Abstract: A reversible reel assembly including two rotatable reels for successively, continuously winding rolled strip. The two reels are mounted on a rotatable head plate and are rotatably driven independently from each other. In order to supply the positioning drives of the reels with drive media, rotatable media supplies which are trouble-prone and expensive are required. In order to provide a reversible reel assembly without trouble-prone media supplies, a reel is suggested in which the reel drums are continuously spread-apart by means of the force of a spring and the positioning drives are arranged stationary independently from the reels, so that the reels can be moved into the positioning drives in certain positions and the movement of the segments between a position of rest and a spread-apart position can be effected in these positions.
