1420178 Straightening KUNTSEVSKY ORDENA TRUDOVOGO KRASNOGO ZNAMENI IGOLNO - PLATINNY ZAVOD IMENI KIM 18 April 1973 [19 April 1972] 18668/73 Heading B3E Apparatus for shaping articles of varying section, e.g. needles 2, comprises a table 1 on which the articles are laid side-by-side and a clamp 3 above the table, the clamp and table having cut-out portions so that portions of the articles extend into the cut-out areas, a row of rollers above the portions of the articles, a row of rollers below the portions of the articles, and cam and lever mechanism to operate the clamp and reciprocate the rollers. Fig. 3 shows where the table 1 is cut away at 6 and 11, the clamp 3 being shaped correspondingly, so that as an array of needles 2 moves from left to right in Figs. 1 and 3, their heels 10 pass along a groove 9, Fig. 6, in the underside of the clamp, and successively diminishing portions of the sharp ends of the needles are exposed in cutout 6, followed by the butt ends being exposed in cut-out 11. The clamp is raised and lowered by lever 14 operated by cam 16 on shaft 17, rollers 4 above the needles are reciprocated by levers 25-29 operated by cam 38, and rollers 4 below the needles are reciprocated by levers 30- 34 operated by cam 42. In operation, the needles are advanced across the table whenever the clamp is raised by device 43 operated by ratchet mechanism 5 driven by shaft 17, so that each needle first has its exposed sharp end bent bown, Fig. 6, then up, then a lesser length is exposed and bent down, then up, and so on, and finally its butt is bent down, then up.
