Abstract of the Disclosure, The pile is trimmed from selected regions of pile fabrics by applying stiffening agent to the region from which the pile is to be trimmed this, stiffening agent is then hardened and the fibers are then severed from the region to which stiffening agent was applied by drawing the fabric past a cutter having a blade which allows the fibers in the untreated regions to deflect out of its path but severs the fibers to which stiffening agent has been applied. Residual stiffening agent is then removed by scouring.
