Abstract

PURPOSE: To provide a roll cutter in which a rolled product is subjected to narrow drawing, and cut off by a pair of cutting edges, being subjected to press cutting thereby to cut the end part of the product rectangularly and finely.
CONSTITUTION: The central part of a double-piece rolled article is bitten up to a preselected diameter d1 at the biting part of a roll cutter 30, and expanded up to a width w1 by the expanding part thereof. Then, a groove 30a is formed at the central part the rolled article and a pair of cutting edges are brought into abutment therewith to carry out a primary cutting operation, and the excess metal of the raw material is forced into the groove 30a. Then, the article is cut off up to the bottom part of the groove 30a by one of ithe cutting edges, and another cutting edge is projected and the central part of the article is cut off as if the cutting edge press cuts the same. As a result, the excess metal of the central part does not remain as it is bitten in the cutter, and hence damage of the cutting edges is prevented and the excess metal is accurately cut off.
