ABSTRACT:
A modular system for producing triple-necked open ended containers includes three substantially identical necking modules each having the same frame and identical rotatable turrets which have a plurality of identical necking stations around the periphery. Each necking station includes an annular necking die and a platform and punch which are cam-operated to move towards and away from each other and are maintained in engagement with the cams by pressurized fluid. Each necking station also has a container pressurizing means in the form of an annular chamber which acts as a holding chamber prior to transmitting the pressurized fluid into the container.
