Abstract:
A process for continuously winding a plurality of longitudinally cut paper webs at machine speed by using support rollers and at least one pair of disks associated with each of the support rollers, such that the at least one pair of disks is arranged concentrically with and rotates independently of, its associated support roller, the at least one pair of disks including a first winding device having a first cardboard tube disposed thereon and a second winding device having a second cardboard tube disposed thereon, such that each of the support rollers include at least one of the pair of disks, which are concentrically arranged with and which rotate independently of the support rollers, the process comprising:axially adjusting the disks of the at least one pair of disks to correspond to a width of web to be wound; positioning the pair of disks in a first position; attaching a first end of the web onto the first cardboard tube; running the supporting rollers and the first cardboard tube up to a machine speed thereby winding the web onto the first cardboard tube, wherein the first cardboard tube is driven by a first core winding device; turning the pair of disks around an axis of the associated support roller to a second position; accelerating the second cardboard tube up to machine speed with a second core winding device; cutting the paper web transversely to a web run direction when a desired winding diameter is achieved on the first cardboard tube thereby producing a second end; winding the second end of the web onto the second cardboard tube; turning the pair of disks around an axis of the associated support roller to a third position; stopping the rotation of the first cardboard tube; removing the paper web wound onto the first cardboard tube from the first winding device; and disposing a third cardboard tube onto the first winding device.
