ABSTRACT:
A device for fastening a die, such as a semi-cylindrical element on a tool carrying cylinder, which includes each of the dies having parallel extending ribs provided either with oblique surface portions or an oblique surface, the carrier is provided with circular grooves corresponding to the ribs and longitudinally extending grooves crossing the circular grooves which support locking rods. The device also includes an arrangement for shifting the locking rods from a released position to a locking position. In one embodiment, each of the locking rods has a notch for receiving the ribs and is provided with an oblique surface for engaging the oblique surface portion of the rib to lock the rib in the circular groove as the rods assume a locking position. In a second embodiment, each of the circular grooves has an oblique side wall and each of the rods urges the rib against the oblique side wall to cause a locking of the rib in the groove.
