Title: Improvements in or relating to machines suitable for treating sheet materials
IPC: C14B1/10
Filed: 1953-04-01
Abstract: 723,565. Rotating tool apparatus. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). April 1, 1953 [April 2, 1952], No. 8340/52. Class 76. A machine suitable for treating sheet materials such as hides and skins so constructed and arranged that each workpiece treated by the machine is folded and discharged with the folded portion of the workpiece leading, has a surface over which spread-out workpieces may be consecutively presented from the front of the machine, said surface extending above and terminating rearwardly of a work treating zone in the machine, there being also means for receiving and feeding each of said workpieces through said zone subsequently to a stage in which the leading edge thereof depends from the rearward end portion of said surface. In Fig. 5, which is a side elevation of a machine suitable for fleshing hides, the workpiece is fed over the easing 294 so that the leading edge depends from the rearward end 300, the bed roll 130 being then to the right of the depending workpiece. When a suitable length is depending into the machine a lever (not shown in Fig. 5) is moved, which sets a cycle of operations controlled by a fluidpressure system (which is described in detail) into operation, whereby the bed rolls are moved horizontally at the appropriate times. First the roll 130 moves into the position shown, thereby bringing the workpiece into contact with the helical blades of the upper treating rolls 60 rotating in the same direction, and cooperating with an upper feed roll 240. When that portion of the workpiece which has already been operated on is opposite the lower fleshing roll 44, the lower bed roll 80 moves forward and presses the workpiece against the fleshing roll and the lower feed roll 212 which are situated similarly to the upper set. As the rolls continue to revolve both ends of the workpiece are thus operated on and discharged by the feed rolls 212 and 240 rearwardly with a folded portion leading. The bed rolls then return to their original position. Other features of the apparatus or its arrangement include the work guiding member 302 ; yieldable mounting of the feed rolls on levers 216 &c. pivoted about the shafts 220 &c. and attached to spring-loaded assemblies 238 etc.; the use of fluid motors driven by power pump units by a flexible conduit to rotate the bed rolls and feed rolls, thereby permitting non-rotational movement without disturbing their continuous rotation.
