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. The movement mechanism is arranged so that it displaces the movable holding jaw in a radial or axial direction relative to the axis of rotation of the tool ring to engage and position the elongate body and then clamp the elongate body by the holding trays with greater force to hold the elongate body securely while the head is formed thereon.
