Abstract:
1. A cutting- and creasing-wheel assembly comprising: a pair of creasing-wheels of equal radial dimensions, arranged axially separated and rotating with their centers located on a common axis of rotation, and narrowly spaced to create a singular creasing line in a compressible web material; a circular cutting-wheel journalled for rotation between the creasing-wheels at an axis of rotation which is separate and arranged displaceable from said axis of rotation through the centers of the creasing-wheels; the cutting-wheel having a cutting edge on its periphery at a radius which is less than the radius of the creasing-wheels, wherein the cutting-wheel is controllable, through displacement of its axis of rotation, to move between the creasing-wheels from a non-operative position radially inside the outer peripheries of the creasing-wheels to an operative position wherein the cutting edge projects radially outside said outer peripheries, whereby the cutting- and creasing-wheel assembly is controllable simultaneously to perform cutting and creasing at substantially the same point of contact with the web material.
