ABSTRACT:
A container for drawing or ironing dies is particularly useful but is not limited to can making. It includes an outer ring having an inwardly extending flange at one end and a disc secured to its other end so as to provide a peripheral space for receiving at least three segments which are resiliently urged against a die ring. The radial length of the slot is greater than the radial length of the segments so that the die ring can be displaced from the normal axis of the die pack. Means co-axial with the normal axis of the die limit inward movement of the segments.
