Abstract: The present invention relates to aspects of securing holding jaws in nail machines, including a method, a machine, a tool ring and a holding jaw for such purposes. The novel aspects of the invention include that holding jaws are secured to a tool ring in a manner where a number of immovably secured passive fittings are used as well as a number of active fittings. It is hereby ensured that holding jaws may be e.g. replaced without loosening many other holding jaws, and that the holding jaws may be placed very precisely and in a manner, which is repeatable. It is also ensured that the holding jaws may be effectively and easily secured.

Abstract: A nail machine and a tool ring for securing elongate bodies in the manufacture of heads on the elongate bodies. The tool ring has an axis of rotation, an outer circumference and a surface that extends substantially perpendicular to the axis fo rotation, and wherein the tool ring comprises a number of engagement devices spaced substantially equally at the circumference of the tool ring for receiving and releasably securing the elongate bodies. Each of the engagement devices has two mutually opposed holding jaws, at least one of which is movable and arranged on a movement mechanism so that it can be displaced towards and away from the opposed holding jaw. The engagement devices also have two opposed holding trays which are movable towards one another.
