DEVICE FOR RUPTURING ATTACHMENT ZONES ON FOLDING BOXES AND PRODUCTION UNIT COMPRISING SUCH A RUPTURE DEVICE

摘要

The invention relates to a rupture device (1) comprising: an upper pressure member (2); a support part (4) for supporting the stack, said support part including multiple conveyor members (10) for conveying the stack in a conveying direction (X); and a lower pressure member (6) arranged below the conveyor members (10). The conveyor members (10) are adjacent to one another in a transverse direction (Y). Two adjacent conveyor members (10) can be moved apart from one another. The lower pressure member (6) comprises: i) two lower adjacent plates (6.1, 6.2) which can be moved apart from one another, and ii) a lower linear-movement actuator (6.3) for moving the lower plates (6.1, 6.2) so as to align the rupture slit (2.0) with a rupture line.
