Device for winding and changing the reels of web material as well as a dedicated process

A device for winding and changing reels of a web material, the device comprising

• a machine housing with rails,
• first and second central drives, the first and second central drives independently operable to drive a winding shaft,
• a drivable winding shaft guide which travels on the rails and interacts in each case with one of the first and second central drives and which drives these on the rails between a parking position and a winding position,
• a contact roller unit which interacts with the winding shaft in the winding position driven by the respective central drive,
• slitting units to cut through the web material,
• winding shaft transport units to feed a new winding shaft for a winding shaft change, and
• a reel removal device,
• wherein for a winding shaft change, the drivable winding shaft guide together with the first central drive, which drives a finished reel onto the winding shaft, is drivable from the winding position into the parking position,
• wherein the first central drive is disconnectable from the drivable winding shaft guide and connected to the parking position,
• wherein the second central drive is connectable to the drivable winding shaft guide and is drivable driven from the parking position into the winding position where the second central drive is connectable to the new winding shaft and is drivable,
• wherein the contact roller unit is drivable towards the new winding shaft and interacts with the new winding shaft, and
• wherein the web material is cut off by the slitting device and can be wound up to a new reel.
