Abstract of the Disclosure The invention relates to a device for the burr-free cutting of strip-shaped material, especially made of metal, which has, for each cut, two pairs of circular knives on axis-parallel knife shafts. The strip-shaped material is cut into by the first pair of circular knives in the first parting step and is severed in the opposite direc- tion by the second pair of circular knives in the second parting step. The characteristic feature of the invention is that the counter-knives of the two pairs of circular knives are arranged on a common knife shaft so as to rest against one another, and that they consist of an outer rigid, especially metallic, cutting ring and of an inner annular elastomeric hub part.
