ABSTRACT:
In the perforation of sheet material including leather, artificial leather, foam, paper, filter paper, cardboard and foils by at least one group of spikes with perforating spikes, the individual pieces (9) of the sheet material are held on an endless conveyor device (2) and are pulled off the perforating spikes by a hold-down band (10a) which moves synchronously with the conveyor. It is especially advantageous that the at least one group of spikes is in each instance formed by a spike roller (7) and the hold-down band (10a) passes synchronously with the pieces (9) through the roller gap (8) of the at least one spike roller (7).
