Abstract

The apparatus has a support for the matrix and a support for the punch which is of corresponding shape to the matrix. The supports are placed on opposite sides of the articles to be cut. The punch and its support are carried on the end of a rod which can slide through a hole previously cut in the article and through the piston of a hydraulic jack which provides the power to move the punch. Other known methods of displacement of the punch may also be used.
