Description:

Claim:

My invention relates to a machine for trimming, beading, flanging and forming, not only large, but small stampings without the use of presses and/or dies. Heretofore this work has been done primarily by expensive presses and dies. There has long been a demand for a machine which would do this work without the use of presses and dies. Therefore, I have with my invention, solved this problem by providing a rotary machine which eliminates entirely the use of presses and dies and at the same time produces the results of a press combined with a smooth, clean-cutting action of a rotary shear.
