A process and apparatus for producing metal balls from a 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 a direction of displacement, wherein the jaws are located displaceably relative to one another such that U-grooves, which are located opposite one another on the 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. The blank is fed by a feed device, via a feed channel, to an opening of the shaping channel and is cut off from the strand, by a cutting tool, beforehand, wherein the wire (1) is inserted through a shearing opening (2), which opens transversely into the feed channel (7), until it reaches a stop (3), which is located opposite the shearing opening (2), and is cut off by a shearing cutter (5), which is associated with the shearing opening (2), in the direction in which the feed channel (7) progresses. The stroke of the shearing cutter (5) advances a plurality of wire sections (6), which are located parallel to one another in the direction of a mouth opening of the shaping channel, wherein once the shearing stroke has ended, the foremost wire section (6) is fed to a shaping operation.
