ABSTRACT:
Apparatus and method to raise the edge fibers of a cut pile carpet tile to ensure that they are cut by the rotating shear which is cutting the rest of the fibers in the tile. The tiles are overfed into the shear so that they abut one another causing the edge fiber, on the edge transverse to the direction of travel of the tiles, to be pushed upwardly. At a position adjacent the shearing member air under pressure is supplied against the traveling edge of the carpet tile to project the edge fibers into the upstanding position.
