A device for winding and changing reels of web material includes two independently operable central drives for shifting winding shafts, a drivable winding shaft guide, a contact roller unit and slitting units. Both right-hand winding and left-hand winding are realized, whereby the device is without a prewinding station. For a winding shaft change, the drivable winding shaft guide is driven from the winding position into the parking position and is disconnected. Subsequently, the second central drive is connected to the winding shaft guide and is driven from its parking position into the winding position where the second central drive is connected with a new winding shaft. The contact roller unit is driven against the winding shaft and the web material is cut through by a slitting device and then wound to a new reel.

The invention relates to a process to regulate the film thickness of tubular film manufactured using a film blowing process, wherein the film is laid flat and repositioned using an oscillating take-off unit and subsequently monoaxially oriented in machine direction using an orientation unit. This process produces a film whose thickness profile has as few deviations as possible from the average film thickness across the film width. This result is achieved by setting the film thickness profile of tubular film produced with a film blowing line such that after orientation and as a result of deviations during orientation, a film thickness profile develops that is uniform across the entire film width.
