A TOOL RING AND A NAIL MACHINE COMPRISING SUCH TOOL RING

摘要

The invention provides a nail machine and a tool ring forsecuring preferably elongate bodies in a nail machine, e.g. forthe manufacture of heads on said elongate bodies, said tool ringhaving an axis of rotation, an outer circumference and a surfacethat extends substantially perpendicular to the axis of rotation, andwherein the tool ring further comprises a number of engagementdevices intended for receiving and releasably securing bodies, andwhich are spaced substantially equally apart at the circumferenceof the tool ring, said engagement devices each comprising twomutually opposed holding jaws; and wherein at least the oneof the two holding jaws is/are movable, it being arranged on amovement mechanism so configured that the holding jaw can bedisplaced towards and away from, respectively, the opposed holdingjaw; and wherein the movement mechanism is so arranged that itdisplaces the holding jaw completely or partially in a radial or axialdirection relative to the axis of rotation of the tool ring. Hereby theproductivity obtained with a given machine comprising a tool ringwith a given number of tools is increased.
