| 1. A beveller for a carpet, the beveller comprising:
a rotatable blade for cutting material, the blade being mounted about an axis of rotation and having an edge which is non-linear
radially;
a stationary counter-knife having an edge mounted adjacent to the blade;
a material support surface adjacent the counter-knife for supporting the carpet, wherein the surface and counter-knife edge
are not co-planar; and
wherein the counter-knife edge generally conforms to a profile of the blade edge to permit the blade edge to pass adjacent
the counter-knife edge, as the blade rotates, to shear material placed between the blade edge and the counter-knife edge;
and
the blade edge is located along an imaginary cylindrical surface formed by the rotation of the cutting edge, so that the cutting
edge of the rotating blade passes the cutting edge of the counter-knife in succession when the rotating blade is turned; and
wherein the material support surface is movable relative to the blade or counter-knife generally along a tangent of the cylindrical
surface.
