Abstract: The cutting mechanism includes a cutter block mounting a knife blade arranged for movement along a slot in a cutting table. The cutter block is driven by a cable and a first drive pulley. The cable extends under and around the first drive pulley and a second pulley, with the first end of the cable fixed to a second end of the cutter block, and the second end of the cable fixed to a first end of the cutter block. The cable and the first and second pulleys are arranged such that when the cutter block lies between the first end of the slot in the table and a center of first drive pulley the first and second ends of the cable are drawn taut thereby stopping movement of the cutter block along the slot towards the first end, and such that when the cutter block lies between the second end of the slot in the table and a center of the second pulley the first and second ends of the cable are likewise drawn taut stopping movement of the cutter block along the slot towards the second end.

Abstract: A sheet material primarily fabric is cut by providing an anvil having an substantially cylindrical wire thereon defining a cutting line lying along the anvil and supported thereby, by draping the fabric over the anvil and by running along the wire of the anvil the peripheral surface of a roller so as to apply pressure between the roller surface and the wire. The fabric is thus compressed between the roller surface and the wire in a pinching action which causes the wire to engage into and effect cutting of the fabric along the cutting line. The roller is mounted on a carriage running along the anvil and is spring biased onto the wire.

Abstract: An apparatus for forming a spread of generally thin, pliable material from a roll thereof onto a table includes a cradle for holding the roll of the material which is selectively operable to rotate the roll of material for feeding a web of material generally forwardly from the roll. An endless conveyor including a series of flights spaced at intervals therealong with openings between the flights is driven for forward travel, and the web from the roll of the material is received on and carried forward by a flight in the upper reach of the conveyor. A knife is operable to cut the web to separate a first sheet of material from the roll of material. The first sheet of material is thereafter held from forward movement with the supporting flight by grippers selectively operable for gripping the first sheet of material on the supporting flight in the upper reach of the conveyor. Thus, the supporting flight slides out from under the first sheet of material with the first sheet falling onto the table.
