Abstract
The invention relates to a device for use in apparatus for winding continuously-fed material on a winding mandrel for exchanging winding mandrels without interrupting the supply of tape or sheet material to be wound. Two endless cooperating conveyors are provided to which the ends of the winding mandrels are coupled to permit the horizontal transport of an empty winding mandrel received from a store to a winding station and to a removal station after receiving a full roll. The conveyors have sets of parallel, closely spaced bars, the axes of which are arranged perpendicularly with respect to the direction of movement of the conveyors and the ends of the winding mandrels are allowed to move vertically along the gaps between the bars as the diameter of the roll of material changes on the winding mandrel.
