CA 2141891

A tearing-off roller pair, for tearing off sections or strips divided off by perforation cuts from a material web, consists of a first roller with a substantially smooth steel shell and, applied against it, a second roller with a body set into it for increasing the contact pressure, which body projects over its peripheral surface in its unstressed state. To allow a greater retaining force to be exerted on the sections to be torn off, several interspaced resilient bodies are set in recesses along a generator of the second roller.
