  • Patent number: 10532904
    Abstract: A winding station and a method for winding material webs, in particular foils or films, wherein during a continuous movement of the material web, a removal fork pivots the nearly full winding sleeve from a front position to a rear removal position while a new winding sleeve is moved to the winding position. The winding station is provided with a device to wind the material web automatically onto a new winding sleeve following the separation of the completed winding.

  • Patent number: 7597282
    Abstract: A drum support arm supports a cutting drum with a sector cross section and a receiving drum with a circular cross section, and moves between a web winding changeover position for causing the receiving drum to contact a core and a spacing position for keeping the receiving drum away from the core. The guide roller moves between an approaching position for lifting a web from the receiving drum and a retracted position for causing the web contact a peripheral surface of the receiving drum. When the drum support arm moves to the web winding changeover position, the guide roller moves to the retracted position, and when the drum support arm moves to the spacing position, the guide roller moves to the approaching position. When the drum support arm is set to the web winding changeover position, the cutting drum rotates once to cut the web. A front end of the web formed by cutting is pressed against the core by the receiving drum and wound around the periphery of the core.

  • Patent number: 6926224
    Abstract: A web is wound onto a core (21) while supported by winding drums (11, 12). The web is cut by a cutting device (19), and a finished web roll (10) is removed by a transfer device (16). A new core (21) is moved to a space between the winding drums (11, 12), and the winding is stopped to remove the finished roll (10) and to start a new roll. The core is moved onto support of one winding drum and a support member (22) and held in place by the support member (22) until the movable winding drum (11, 12) has been moved to the starting position of winding.
