Abstract
A cutter for a double-pile loom which cutter is fixed to a slider to slide on a rail in parallel with the cloth fell. The cutter is adapted to reciprocate crosswise in the space between the top and bottom sheets of fabric synchronously with picking to cut the pile yarns which stitch together two sheets of fabric to form piles. The cutter edge is made of a single crystal sapphire and is highly resistant to wear having its cutting characteristics maintained for a long term. Grindstones are not needed to maintain a sharpness of the cutter.
