Total least squares based subband modelling for scalable speech representations with damped sinusoids

A carpet cutter is disclosed which is used to cut any excess edges of a carpet to the size of a room after it has been laid in the room. The carpet is cut at its bend toward the wall. It includes a bed plate slid on the carpet, a guide plate at front of the bed plate to be pressed against the wall, a slanting blade mounting plate in the rear of the guide plate, a pair of blades mounted on the blade mounting plate, and a pair of presser rollers disposed outside of the blades for pressing down the carpet against the floor just before cutting. The carpet is cut by one blade slantly mounted so as for its edge to butt on the wall surface. The clamping nuts for the blades are tightened in reverse direction to each other. Therefore, there is no fear of the blade coming loose by contact with the carpet during cutting. The position of the presser rollers can be adjusted by means of one adjusting mechanism provided in the center according to the thickness of the carpet. This enables the cutter to cut a carpet of any thickness with simple adjustment.
