ABSTRACT:
A shear die is axially divided into a pair of die portions 18,19 between which a holding cavity 22 is formed, wherein the holding cavity has a diameter that is less than that of material "a" so that when one of the die portions is forced against the other die portion under a biasing effect of a spring 25, the material will be firmly held in the die cavity ensuring that the material can be cut to a predetermined volume and present a smooth cut surface, and the cutter arbor 4 is provided with a releasing member 34 adapted to release the one die portion 19 from the effect of the spring 25 as the cutter arbor 4 is retracted to facilitate additional material being moved into the die cavity for a subsequent cutting operation.
