Abstract
An improved box blank die cutting machine (20) is provided which includes die changeover apparatus (32) permitting the machine die structure (28) to be rapidly changed without the necessity for completely removing the die frame (26) from the machine (20). The changeover apparatus (32) includes die-supporting elements (156, 158) designed to support the die frame (26) as it is shifted rearwardly towards the output end (46) of the machine (20). Moreover, the elements (158) include selectively extensible pins (184a, 184b) which are received within corresponding die frame apertures (108, 110), so that the die frame (26) may be pivoted to an upright die changeover position. Limit stops (188, 190) are also provided for limiting the pivoting movement of the die frame (26), and for stabilizing the die frame (26) in its upright position.
