Abstract
A cutting device having a circular cutting blade which is mounted so that it can rotate and is supported so that it can be displaced across a web of material to be cut. This circular cutting blade is partially accommodated in a tubular member which is equipped with a slit and extends across the web of material. The member is of metal and spring-loaded so as to rotate towards the circular blade, causing it to rest against and co-act with the latter so that as the circular blade is displaced along the accommodating member with close contact it is made to rotate, while simultaneously being sharpened by the metal member.
Claims12
An apparatus for cutting a web of material, comprising:
- a circular cutting blade having a circumferential cutting edge and being rotatable about an axis perpendicular to said blade;
- means for moving said cutting blade across the web so that said axis moves parallel to itself in a plane;
- a tubular accomodating member having a longitudinal axis extending essentially parallel to said plane and having a longitudinal slot therein defined by a metal edge receiving therein the circumferential cutting edge;
- and means biasing said tubular member to rotate so that said edge rests against said circumferential cutting edge;
- whereby said blade is rotated when said moving means moves said blade across the web and said cutting edge is sharpened.
