  • Patent number: 10005635
    Abstract: The present invention relates to a method and a device for producing a roll (18) made of a material web (5) of flexible material which is guided via a contact roller (19) of a winder and is wound in the said winder to form a roll (18), wherein the contact roller (19) maintains contact with the roll (18) during winding and the wrap angle (?) of the material web (5) passing over the contact roller (19), as the former is progressively wound, is maintained throughout at a variable reference value predetermined for each winding. In this way the wrap angle (?) for the winding can be adapted to the respective composition of the material web (5), which improves the quality of the winding.

  • Patent number: 5437417
    Abstract: A device for winding a web, preferably a plastic film web produced in a blowing or casting process, includes a driven winding tube for a web, a web tension measuring roller, a driven contact roller positioned between the winding tube and the web tension measuring roller which, in the case of contact winding, can be positioned against the film roll being formed and which, in the case of gap winding, is positioned at a distance from the film roll. A control device controls the motors as a function of the feeding speed of the web and in accordance with the measured tractive force of the web, such that the coil hardness of the wound roll can be predetermined. In the case of contact winding, the torque of the winding motor is controlled according to the increasing diameter of the wound roll and the contact roller is driven at a speed that is controlled according to the tractive force of the web.

  • Patent number: 5251837
    Abstract: A device for winding webs of material onto winding shafts comprises a movable bearing supporting a winding shaft during winding, through which the supply roll being formed can be moved towards a contact roller and which can be moved in a position away therefrom for the removal of the completely wound supply roll. A new winding shaft accelerated approximately up to the speed of the web and onto which the cut leading end of the web can be wound, is inserted in the movable bearings. To prevent damage to the web, the weight of the supply roll is supported on the contact roller. The movable bearing is formed by two pairs of holding means, each pair of which can be moved synchronously with the other pair but also independently thereof. The pairs are adapted to hold a supply roll jointly as well as individually to hold a completely wound supply roll or a winding shaft with the leading end of the web wound thereon.

  • Patent number: 5137224
    Abstract: A winding spindle includes a plurality of support and drive rings mounted for free rotation thereon. The drive rings carry and drive winding cores, which have been slipped over the drive rings. The drive rings are able to be non-positively coupled, by their lateral annular flanks, with thrust washers. The thrust washers are connected, in a torque transmitting manner, and slidingly, with the winding spindle, and are acted upon by a thrust. In order to couple the support and drive rings to the winding spindle with an essentially constant torque along the length of the winding spindle, endless hose sections are associated with each thrust washer. The endless hose sections act to press the thrust washers directly against respective flanks of the support and drive rings with uniform force.

  • Patent number: 4767075
    Abstract: 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.
