Definitions
- the invention relates to a device for winding at least two material webs, in particular of film webs, with at least two receiving devices, for rotatably supporting at least one winding core, wherein the receiving devices between a winding position for winding at least one web on the winding core and a discharge or loading position at least two winding cores are arranged coaxially in the receiving device for simultaneously winding the material webs on separate winding cores, the winding cores being rotatable in each case in two bearing points provided adjacent to the respective winding core are stored.
- stretch films, office films, decorative films, aluminum foils, diaper films or the like may be provided as film webs.
- other types of webs such as paper webs, composite laminates, textile webs and the like, can be wound up.
- turret winder are already known from the prior art, which have at least one second position for removing a finished winder in addition to the winding position for continuous winding of the material webs. Such winders can also work inline with a production line with which a total material web is made.
- a film winding device in which two laterally arranged drive shafts for receiving in each case a winding tube are provided for winding two film webs on two coaxially arranged winding tubes.
- a bearing element is provided, on both sides of which non-driven bearings are provided for receiving the winding tubes.
- the central bearing element is slidably mounted hiebei, so that the width of the cores can be variably adjusted. Due to the rotary mounting of the two winding tubes in laterally arranged drive shafts, the device according to the JP disclosure font adversely, however, limited to a maximum of two wound material webs.
- the total width is fixed by the laterally arranged drive shafts and it can be reduced by adjusting the central bearing element, only the width of a web to the same extent as the width of the other material web is increased.
- a total web of material having a width of e.g. up to 8 m can be subdivided into webs of a few centimeters to about 75 cm width
- the total material web guided over several guide rollers to a longitudinal cutting station, with which the total material web is cut into several webs.
- IT MI98U000377 For winding such a material web cut into a plurality of material webs, it is known from IT MI98U000377 to set up a corresponding number of winding devices for winding one web of material in succession.
- the disadvantage here is in particular that due to the number of material webs corresponding number of take-up a large space is required, such an overall arrangement is very sensitive to the straight guide of the webs due to the necessary long guidance of the webs of the film longitudinal cutting device to the respective take-up.
- the number of webs of material to be wound up with such a winding system is thus restricted to a maximum of four material webs.
- a change in the width of the webs of material in such a device only at standstill of the system is possible.
- JP 2193851 A yet another device for winding an ink ribbon is described, which is cut with a cutter into a plurality of narrower ribbons. Here, however, a continuous winding shaft is shown, as it should be avoided by the subject invention just.
