Abstract
A web slitting device located in the intermediate space between a product web and two support rolls comprising a blade carrier with blade, which, for the purpose of slitting the web, is connected to a transverse beam so that it can be pivoted toward the web. The blade carrier is designed as an articulated lever, one end of which carries the blade, and the other end (support end), while the blade is slitting, forms a support against the roller not supporting the web, with the result that the blade carrier is automatically locked in position.
