Abstract: A diecutting apparatus is disclosed which accepts interchangeable die cylinders of a variety of lengths and diameters. Rapid replacement, adjustment and reversal of the die is possible. The station has a support bar for mounting the die cylinder and a slidable support for the die cylinder bearing blocks. The bearing blocks slide horizontally along the support bar to accept die cylinders of a variety of lengths. The support bar is mounted at each end on transverse slides which slide vertically to accept die cylinders of a variety of diameters. Mounted above the die cylinder support bar is a support slide on which are mounted contact rollers and pressure cylinders for applying a biasing force to the die cylinder. The slides may be fixed in place for each particular die cylinder used. The pressure cylinders and contact rollers act on bearing surfaces on the die cylinder.
