Abstract

A device is described for joining metal sheets with a male and female die, of the type in which the dies interact to cut or slice through the sheets to form portions of material which are spread via material flow by the die interaction to prevent separation of the sheets. The female die has plates which provide counter-edges which interact with the male punch to provide the desired cutting. The metal plates are leaf springs which yield after the cutting to permit spreading of the material.
