Abstract (en)
[origin: EP0802026A1] A device for perforating webs of foil, in particular plastic foil, has at least one pair of rollers through which the foil is moved. The pair of rollers includes a spiked roller with spikes which extend radially from its outer surface, and a mating roller held against the spiked roller and whose outer surface has a lining which can be penetrated by the point of each spike, for example an elastic outer ply. The outer surface of the spiked roller has at least one recess in which a spike is arranged in such a way that only a section of its point protrudes by a predetermined extent beyond the outer surface.
