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.

An apparatus to shear the fibers on the surface of a pile fabric comprising: a first endless conveyor, guide means on the sides of said first endless conveyor to align a plurality of pile fabrics on said conveyor, a second endless conveyor closely adjacent and in alignment with said first endless conveyor, means driving said first endless conveyor at a pre-determined speed, means driving said second endless conveyor at a speed less than the speed of said first endless conveyor whereby a pile fabric from said first conveyor abuts a pile fabric on said second endless conveyor to cause the pile fibers on the abutting fabric edges to be pushed upwardly and a cutter mechanism operably associated and located above said second endless conveyor to shear the surface of a pile fabric on said second endless conveyor. The method of shearing the pile surface of a pile carpet tile having predetermined dimensions comprising the steps of placing a plurality of carpet tiles on a first conveyor, aligning the carpet tiles on the first conveyor, supplying the carpet tiles from the first conveyor onto a second conveyor, driving the second conveyor at a speed slower than the first conveyor so that the carpet tiles abut one another on the second conveyor and push the fibers on the transverse edges of the abutting carpet tiles in an upward direction, forcing the fibers on the longitudinal edges of the abutting tiles in an upward direction and shearing the surface of the carpet tiles on the second conveyor after the fibers on the transverse and longitudinal edges have been forced in an upward direction.
