Abstract
This severing device (1) includes an upper pressing member (2), a pile support part (4) having a plurality of conveying members (10) for conveying the pile in a conveying direction (X), a lower pressing member (6) arranged under the conveying members (10). The conveying members (10) are juxtaposed in a transverse direction. Two juxtaposed conveying members can be parted. The lower pressing member (6) has: i) two adjacent lower plates (6.1, 6.2) that can be moved apart, and ii) a lower translation actuator (6.3) for moving the lower plates (6.1, 6.2) so as to cause the severance slot (2.0) between juxtaposed conveying members to coincide with a frangible line in the plate.
