Abstract: In a first aspect there is provided a cutting apparatus for cutting material by a shearing action. The cutting apparatus comprises a first arm comprising a first cutting blade and a second arm comprising a second cutting blade. The second arm is operatively associated with the first arm and mounted relative to the first arm so as to define a cutting region between the first cutting blade and the second cutting blade in which cutting region a cutting operation of material is in use effected as a result of cooperation between the first cutting blade and the second cutting blade. At least one of the first and the second arm is operatively mounted so as to pivot about a pivot axis relative to the other arm.

Abstract: Cutting apparatus for cutting material, the apparatus comprising two blades arranged so that in use together they can effect a cutting operation in a cutting region therebetween, the blades being mounted relative to one another so that they are urged together in the cutting region as a result of a cutting force initiated by the cutting operation. In one embodiment at least one of the blades is mounted for pivotal movement about a pivot axis so that during the cutting operation the cutting or shearing force generated causes the blade to be pivotally urged towards the other blade. In another embodiment one blade is a rotatable cutter blade and the other blade is a further cutter blade which is adapted to cooperate together to perform the cutting operation in a cutting region, the further cutting blade being mounted so as to be urged towards the rotatable blade as a result of the cutting or shearing forces generated during the cutting operation.

Abstract: A manually operable cutter device for cutting flexible sheet material, the cutter device comprising a cutter body and a cutting blade assembly operatively mounted to the cutter body and including a rotatable cutter blade having a peripheral edge portion and a fixed cutter blade adapted to cooperate together to provide a cutting zone in which sheet material can be cut. The rotatable cutting blade is mounted for rotation about an axis which extends generally laterally with respect to a normal feed direction of the sheet material to the cutting zone and the direction of rotation of the peripheral edge portion through the cutting zone is in the normal feed direction. The tangential peripheral speed of the rotating cutter blade in the cutting zone is not less than the speed of the feed of sheet material to the cutting zone.
