Abstract: A method of and device for cutting blocks of foamed material, e.g. polyethylene an endless cable of elastic wear resistant material e.g. steel, having a rough surface and a diameter of from 0.5 to 2 mm is preloaded at a force of from 5 to 30 kg. The cable is operated at a speed of rotation of from 30 to 60 m/sec while the foamed material is being moved relative thereto toward the foamed material to be cut along a plane extending in a direction transverse to the direction of movement of the cable. The cable of elastic material having helically wound therearound a wear resistant wire with a diameter of from 0.1 to 0.3 mm.

Abstract: An upholstering body for use as the seat, or back, or as a combination seat and back in an article of furniture in which the body has an outer layer of resilient material such as a foamed elastomeric material and a supporting core member in the form of a sheet, or plate, of synthetic material, polyester resin, for example. The sheet is preferably reinforced with glass fibers, which may be in the form of glass cloth. The sheet is adapted for anchoring to a furniture frame in such a manner that the sheet is yieldable in the direction in which a load is normally applied thereto while being generally unyieldable in other directions.
