<p>A cutting- and creasing -wheel assembly includes a cutting tool, such as a circular disc having a continuous or a serrated cutting edge. The disc is rotatable and supported between a pair of rotatable creasing- wheel halves, the creasing-wheel halves being of equal radial dimension. The disc is controllable for movement between a non-operative position wherein the cutting edge is withdrawn radially inside the outer peripheries of the creasing-wheel halves, and an operative position wherein the cutting edge is projecting radially outside the peripheries. The method of slitting a corrugated or otherwise compressible material involves the provision and control of a cutting tool, preferably a circular disc having a continuous or serrated cutting edge. The disc is arranged to be rotatable and movably supported between a pair of rotatable creasing-wheel halves of equal radial dimension in a cutting- and creasing wheel assembly.</p> |
