Abstract (en)
[origin: US4835850A] An apparatus for joining two or more sheets by means of drawn and extruded material portions comprising a punch, a die and an anvil. The punch is driven to first cooperate with the die in a drawing step, then to transport the work piece to the anvil and to perform in cooperation with the latter an extrusion step. Preferably, a plurality of punches is driven to rotate and to cooperate with a die-and-anvil assembly common to all punches.
