  • Patent number: 4733552
    Abstract: A press assembly is disclosed with a series of punch/die sets for successive operations on parts connected together in a strip. The punch/die sets are conveniently relocatable anywhere on regularly-spaced fixed stations and the stations can receive more than one punch/die set. The punches and dies in the sets can be mounted on removable base plates or otherwise made movable to any spacing, such that the sets are easily spaced to reflect a length of the parts being manufactured. The increment of strip feed between operations of the press is also adjustable. The press assembly can therefore be inexpensively set up to make parts of any characteristic length.
