The invention describes a roll-removal device by means of which a plurality of rolls which have been wound to completion are transported away from a winding shaft having a displacement device for displacing the rolls relative to the winding shaft, in order to withdraw the rolls from the winding shaft, having a receiving device for receiving the rolls, and having a transfer device for transferring the rolls from the displacement device to the receiving device, wherein the rolls can be rolled freely at least in certain regions, the rolls rolling about their rolling axes.

By means of this device for changing the position of the rolls axes, the roll axes of two adjacent rolls can be moved to an angle of less than 180 degrees in relation to one another.

A multifunctional apparatus of automatic punching, laminating, tape-preparing and cutting for a tailing end of a coiled material and a method associated therewith are provided. The apparatus is provided with a winding device and the coiled material. The coiled material is wound on a rotating shaft of the winding device. A robotic arm is disposed above the winding device. One end of the robotic arm is mounted with a punching, tape-preparing and cutting mechanism, and the other end thereof is rotatably connected to a centering and deviating-correcting mechanism fixed on a winding diameter tracking mechanism. The robotic arm is driven by a motor or a pneumatic cylinder or a hydraulic cylinder. The winding diameter tracking mechanism is slidably disposed on a rail of a rack. The apparatus and method can improve efficiencies of winding and jointing of coiled materials, and reduce production cost.
