<p>Coacting die cylinders (10, 12) with one cylinder (10) having a cutting blade (14) and the other cylinder (12) having an anvil surface (16) which when rotating cooperate to cut a blank from a web of low density material. The blade and the anvil surface (16, 22) are tapered in opposite axial directions so that the clearance between them can be readily varied and adjusted by moving the cylinders (10, 12) axially relative to each other. Preferably, the cylinders (10, 12) each have a pair of cylindrical bearers (26, 28) which are in contact and rolling engagement with each other. The die cylinders (10, 12) are journal led in bearing means (40, 52, 54, 56) which are removably received in the stand (30) to facilitate easy removal and installation of the die cylinders (10, 12) when desired.</p> |
