Abstract (en)
[origin: EP0864404A2] The cut-out sheets (9) of flat material are conveyed by a continuous conveyor (2) into the operating range of at least one group of needles and removed from the perforating needles by at least one holder. The cut-out sheets are held on the conveyor by a holding-down belt (10) moved together with the conveyor and permeable by the perforating needles. The holding-down belt moves in synchronisation with the cut-out pieces through the operating range of at least one needle-roller (7). A guide roller (15,16) is positioned in front of the first and at least behind the last, needle roller.
