ABSTRACT:
An arrangement for diagonally cutting up the end of a rectangular tube is provided. In order to be able to utilize the shearing principle with such diagonal cuts, the clamping jaws are arranged as stationary shearing blades having shearing edges that define a cutting plane. The rectangular tube being cut to size is diagonally inserted between the clamping jaws so that a pocket which is to be cut off stands out beyond the cutting plane. A shearing knife moves along the pocket and has an arrow-like shearing edge which inserts into this pocket-shaped projecting end and cuts off the end from the inside against the stationary cutting blade. Each of the three stationary cutting edges is brushed off by the movable cutting edge by at least one movable component.
