Abstract

In a notching machine with an upper blade (6, 7) and a lower blade (21, 22), the ram (5) is designed as a tubular hollow body. The cutting gap (23) between the two blades lies within the inside diameter of the hollow body. As a result, the cutting forces act for all practical purposes along the principal axis of the ram and this simplifies the mounting. <IMAGE>
