DEVICE AND METHOD FOR CUTTING, PERFORATING OR FOLDING A THIN BENDABLE MATERIAL

摘要

The invention relates to a cutting device (1) and a method for repeatedly lateral cutting off an advancing material track (10) comprising a first rotating drum (2) comprising at least one knife (4) and a second rotating drum (3) comprising at least one knife (5), which at least one knife (4) of said first rotating drum (2) cooperates with at least one anvil or with at least one opposite knife arranged on said second rotating drum (3) in such a way that said at least one knife (4) on said first rotating drum (2) cuts off the material track (10) against said at least one anvil or at least one opposite knife of said second rotating drum (3) and that said at least one knife (5) on said second rotating drum (3) cooperates with at least one anvil or with at least one opposite knife arranged on said first rotating drum (2) in such a way that said at least one knife (5) on said second rotating drum (3) cuts off the material track (10) against said at least one anvil or at least one opposite knife of said first rotating drum (2), whereby said advancing material track (10) may be cut off at least twice on every turn.
