Abstract
The present invention relates to a method for processing a covering roll sheet (20) of a package, wherein the covering roll sheet (20) covers a package body (51) in the manner of a lid, comprising the steps of: drawing the covering roll sheet (20) off an endless roll (22), tensioning the covering roll sheet (20), determining an offset between a first marking on the covering roll sheet (20) and a second marking (34) on the package body (51), and stretching the covering roll sheet (20) in a manner dependent on the determined offset between the first marking (33) and the second marking (34).
Claims13
A method for processing a cover web (20) of a package, wherein the cover web (20) covers a packaging body (51) in the manner of a lid, comprising the steps:
- unreeling the cover web (20) from an endless reel (22),
- tensioning the cover web (20),
- determining a misalignment between a first mark on the cover web (20) and a second mark (34) on the packaging body (51),
- clamping a section of the cover web (20) between a plurality of clamping jaws (43),
- stretching the cover web (20) by an elongated expanding device (41) engaging the section of the cover web (20) between the plurality of clamping jaws (43) depending on the determined misalignment between the first mark (33) and the second mark (34).
A device for processing a cover web (20) of a package (5), wherein the cover web (20) is configured to cover a packaging body (51) in the manner of a lid, comprising:
- an unreeling device (2) for unreeling the cover web (20) from an endless reel (22),
- a first detection sensor (31) for detecting a first mark (33) on the cover web (20) and a second detection sensor (32) for detecting a second mark (34) on the packaging body (51) or a packaging body web,
- a plurality of clamping jaws (43) for clamping a section of the cover web (20),
- a stretching device (4), including an elongated expanding device (41) which is configured to engage the section of the cover web (20) between the plurality of clamping jaws (43) to perform a stretching process, and
- a control unit (7) which is configured to control the stretching process based on a detected misalignment between the first mark (33) and the second mark (34).
