Abstract:
An apparatus for producing, in particular, small metal balls from cylindrical strand material, with two rolling jaws which are displaceable relative to one another and of which each forms a shaping groove which extends in the direction of displacement, wherein the jaws are located displaceably with respect to one another such that U-grooves, which are located opposite one another on an opening side, form a shaping channel, a blank being rolled, as a result of displacement of the channel walls relative to one another, on its passage through said shaping channel, and with a feed device for feeding the blanks, which are cut off from the strand by a cutting tool, via a feed channel, to an opening of the shaping channel, the apparatus comprising:a shearing opening (2), which opens out transversely into a location of the feed channel (7) at a distance from the opening of the shaping channel, wherein and through which a strand end is insertable across the feed channel until the strand end projects against a stop (3), said stop being located opposite the shearing opening (2), anda shearing cutter (5) which is associated with the shearing opening (2), said shearing cutter being displaceable in direction of the feed channel (7) and, upon shearing off the blanks (6), advances the blanks (6) into a length of the feed channel between said location and said opening of the shaping channel, which blanks are located parallel to one another and arranged in a row in the length of the feed channel, in direction of the opening of the shaping channel, the length of the feed channel being greater than the diameters of a plurality of the blanks for holding the row of blanks.
