Patent ID: 7481390

Claim:
A device for winding a web, the device comprising: device frame parts; guide rollers arranged in the device frame parts for guiding the web; a counter roller mounted in the device frame parts for feeding the web; a rotatable winding shaft; a carrier unit provided as a support for the winding shaft, wherein the winding shaft is linearly movably mounted on the carrier unit; wherein the winding shaft cooperates circumferentially with the counter roller; wherein the winding shaft has a winding drive for continuously winding the web onto a winding sleeve arranged on the winding shaft; wherein the carrier unit is pivotable about a central transverse axis of the device; wherein the carrier unit has two pivot arms; wherein the two pivot arms have at least one holding device that supports the winding shaft so that the winding shaft is linearly movable; wherein the winding drive is connected to the two pivot arms and comprises at least one central drive drivingly connectable to the winding shaft for driving the winding shaft; wherein the two pivot arms have at least one linear guide supporting the at least one holding device; and wherein the at least one holding device moves linearly on the two pivot arms as a diameter of wound material grows on the winding sleeve arranged on the winding shaft as the winding shaft is driven by the at least one central drive drivingly connected to the winding shaft.
