Abstract
A heavy, roller-mounted base plate has thereon a conventional pile carpet trimmer having a shearing head disposed to be swung into and out of a pile access opening in the base plate either to trim the pile of a carpet by sliding the plate on top of the pile, or to bevel the carpet edge by sliding the plate beneath and along one edge of the carpet. Attached to the plate adjacent opposite ends of its pile access opening are two, linearly aligned guide members, which slidably engage a carpet edge during a beveling operation. A retention bracket projects from one of the guide members to overlie the pile surface to prevent any bunching or folding of the carpet edge during the edge-beveling operation.
