Title: Thread trimming method and apparatus
IPC: D06C13/00
Filed: 1964-11-13
Abstract: 1, 043, 929. Trimming fabric; unwinding fabric. HADLEY CO. Inc. Nov. 13, 1964 [Nov. 21, 1963], No. 46309/64. Heading D1S. Relatively long threads 14 attached at one end to a woven web 10 are trimmed by moving the web 10 in a direction lying in the plane of the web, brushing the threads 14 lengthwise or diagonally of the direction of web travel with the attached end leading the free end thereof, brushing the threads 14 forwardly and outwardly of the web 10 and severing the threads whilst they are directed in a direction generally outwardly to the plane of the web. In one embodiment, Fig. 1, the web 10 is advanced over a surface 12 and is contacted tangentially by a laying brush 16 having straight wire bristles which may extend radially outwardly from the surface of a steel core. The brush 16 is rotated by a motor 22 against the advance of the web 10 to lay the threads 14 with their attached ends leading their free ends as shown at 28. Alternatively, the brush 16 may be mounted diagonally, e.g. at an angle of 45 degrees, across the web, Fig. 4 (not shown). A snagging brush 30 comprising a steel core 36 carrying four brush sectors 38 is rotated in the direction of movement of the web 10 by a motor 40 at a peripheral speed in excess, e.g. 25% excess, of the speed of the web 10. The sections 38 may comprise straight wire bristles, Fig. 1, or wires bent forwardly in the direction of rotation, Fig. 3 (not shown). Each thread 14 is pulled forwardly and outwardly from the web 10 by the brush 30 and the web 10 carries the attached end forwardly against a cutting bar 46 which severs the thread. In a modification, Fig. 5 (not shown), brushes 16, 30 and a cutting bar 46 are provided on each side of the web 10. In a further modification, Fig. 6 (not shown), a cutting bar 52 is reciprocated longitudinally of itself by a mechanism 56. In a still further modification, Fig. 7 (not shown), a fixed cutting member 60 is formed with a serrated leading edge 64 and a member-66 having a serrated leading edge 68 is mounted flush to the underside of the member 60 and is reciprocated by a mechanism 70. In another modification, Fig. 8 (not shown), the trimming apparatus is mounted on a frame 72 between a scray and a shearing machine. Severed threads 82 on the snagging brush 84 are removed by a cleaning brush 92 having straight wire bristles and which is rotated in the opposite direction to the brush 84. The threads are removed from the brush 92 through an exhaust hood 94. The web 10 is fed to the trimming apparatus from a roll 98, Fig. 9 (not shown), in a cradle 100 and passes against an idler roll 104 mounted to a frame 106 by arms 108. Springs 110 urge the roll 104 away from a normally open switch 112 which controls a motor 114, Fig. 10 (not shown), to drive the fabric. The machine is operated only when the fabric is unwound from the left hand side of the roll 98, Fig. 9, due to contact of the web 10 with the roller 104 which closes the switch 112. A sewing machine 102 is provided to join together the ends of two sections of the web 10.

Abstract: 1,083,259. Mining conveyers; hydraulic rams. A. G. WILD & CO. Ltd. Feb. 14, 1966 [Nov. 19, 1964], No. 47128/64. Headings B8A and B8J. A face conveyer 22 and a roof support 10, 12, 14, 16 are advanced by a main ram 20 but the spacing between the conveyer and the support is controlled by a buffer ram 32. Base members 14, 16 for hydraulic chocks 10, 12 of the support are connected by a floor beam 18, the front member 14 also supporting a bracket 30 to which the buffer ram 32 is secured. Hydraulic circuitry to the rams includes a manual valve control 40, Fig. 4, the valve as shown being in position to cause advance of the support and base. The same pressure is applied to the piston-rod side of the main ram piston as to that side of the buffer ram piston remote from the piston rod. Since the piston area exposed to fluid in the buffer ram 32 exceeds that in main ram 20, the force exerted by ram 20 cannot overcome the resistance of ram 32 and the advance of the support is halted. The conveyer-support spacing may be varied by adjusting the position of the ram 32, or by providing a plurality of piston rods of unequal lengths or by the provision of extensions for the piston rod. In Fig. 2 (not shown) the control valve is set so as to pressurize the " push " side of the ram 20 and to advance the conveyer.
