Abstract (en)
[origin: US4767075A] In apparatus for winding web material successively onto separate winding cores, the material is fed from a supply via a central guide roller to alternate winding assemblies carried by rotary frames. The apparatus has left- and right-hand rotary frames on opposite sides of the guide roller respectively and there are two winding assemblies on each frame. The winding assemblies can be moved along the frames in horizontal tracks, and the frames can be rotated so as to alternate the positions of the respective winding assemblies relative to the guide roller. The apparatus includes associated web cutters and slitters both for transverse cutting and lengthwise slitting of the web material so that full-width web rolls can be wound, or separate rolls can be wound from adjacent strips which have been slit longitudinally from the web.
