Abstract: A machine for producing e.g. nails by providing oblong shanks (3) with an enlarged heads in one end (4) thereof comprising a rotatably tool ring (2) having a plurality, of holding tools for in one angle position during rotation of the tool ring receiving the shanks, and in another angle position securing the shanks so that they extend radially of the tool ring with each shank having its said end protruding inside the tool ring. Said machine also comprising a rotatably roll (1) mounted inside the tool ring at the securing position of this and adapted for deforming said protruding end of the shanks successively to provide enlarged heads thereon. Said machine further comprising a bending device (25) mounted between the receiving position and the rotatably roll for bending the protruding end of the shanks. Thus the machine according to the invention is able to provide on shanks enlarged heads having larger diameter in proportion to the diameter of the shank than known before.
