Device for manufacturing tubes, particularly packaging tubes, has unit for supplying tube pipe having tube depression, where tube pipe comprises identical single patterns provided at regular intervals along supply direction

摘要

The device has a unit for supplying a tube pipe (16), where the tube pipe comprises identical single patterns (18) provided at regular intervals along a supply direction (14). A cutting unit (12) is provided for cutting the tube pipe in a cutting direction. A control unit (24) is assigned to the cutting unit and generates an activation signal (A) for the cutting unit. The control unit has an optical detection unit (20) and a comparison- and correlation unit, which links current detector data of the detection unit with a detector data of a strip-shaped section of an upstream single pattern. An independent claim is included for a method for manufacturing tubes.
