<p>A cutting- and creasing -wheel assembly according to the invention comprises a cutting tool, such as a circular disc (1) having a continuous or a serrated cutting edge (2). The disc is rotatable and supported between a pair of rotatable creasing- wheel halves (3 and 4), the creasing-wheel halves being of equal radial dimension. The disc is controllable for movement between a non-operative position wherein said cutting edge is withdrawn radially inside the outer peripheries (5) of the creasing-wheel halves, and an operative position wherein the cutting edge (2) is projecting radially outside said peripheries (5). 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. Upon slitting, the disc is controlled for projecting said edge radially outside the peripheries of said creasing-wheel halves to cut a slit through the material while the material is moved relative to the cutting- and creasing wheel assembly, or vice versa.</p> |
