<p>The invention provides a nail machine and a tool ring for securing preferably elongate bodies in a nail machine, e.g. for the manufacture of heads on said elongate bodies, said tool ring having an axis of rotation, an outer circumference and a surface that extends substantially perpendicular to the axis of rotation, and wherein the tool ring further comprises a number of engagement devices intended for receiving and releasably securing bodies, and which are spaced substantially equally apart at the circumference of the tool ring, said engagement devices each comprising two mutually opposed holding jaws; and wherein at least the one of the two holding jaws is/are movable, it being arranged on a movement mechanism so configured that the holding jaw can be displaced towards and away from, respectively, the opposed holding jaw; and wherein the movement mechanism is so arranged that it displaces the holding jaw completely or partially in a radial or axial direction relative to the axis of rotation of the tool ring. Hereby the productivity obtained with a given machine comprising a tool ring with a given number of tools is increased.</p> |
