Abstract

Apparatus for joining a first, non-perforated sheet metal piece to a second, perforated one comprising a male die and a female die, the latter having an anvil which prior to actual joining locates the perforation beneath the male die and is, upon actuation of the apparatus, displaced into a lowered position in which material of the first sheet forced through the perforation by the male die is laterally swaged but is not cut.
