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.
