1,206,355. Grinding. ANCHOR POST PRODUCTS Inc. 9 July, 1968 [21 May, 1968], No. 32776/68. Heading B3D. An abrading machine for abrading the surface of an elongate member such as a strand, wire, pipe or rod, comprises grooved means having a groove for supporting an elongate member therein, an endless abrasive belt aligned transversely of the groove so as to be urgable into surface contact with the elongate member when it is supported in the groove, yielding means for forcing the abrasive belt into contact with an exposed surface of the elongate member, means for moving the belt past the surface of the member so as to abrade the surface and means for rotating the grooved means, endless belt and the means for moving the belt about the elongate member when it is supported in the groove. In one machine described a wire W to be abraded is fed axially of a rotating hollow shaft 13, Fig. 1, and is supported in a groove in a cutaway extension 29 of the shaft 13, Fig. 8, whilst its exposed surface is abraded by a belt B. The belt B is carried by driven and idler carriers 28, 31, respectively, Fig. 1, mounted on a disc 42 secured to the shaft 13 for rotation therewith. The shaft 26 of the carrier 28 is mounted in a bearing arrangement 27 which provides angular adjustment for the carrier 28 to prevent lateral shifting of the belt B. The shaft 32 of carrier 31 is mounted for axial adjustment in a bearing arrangement 34 which itself is pivotally mounted to allow for variation in the tension in the belt B under the action of a spring 108 and turnbuckle 109. In a second embodiment the carrier 31 is driven and means are provided whereby the angular position of the carrier 28 may be adjusted whilst the machine is in operation.
