Tool for the manufacture of an offset head nail and a use of said tool

Abstract

The present invention relates to a tool for the manufacture of an offset head nail, said nail comprising a shank and a head, said head being placed with its center being offset to the center of the shank, wherein said tool is one of a set of at least two tools acting mutually on a blank for a nail, said tool comprising a front side with a reception opening and a top side to be used when forming the head, said reception opening being shaped to form an impression in the blank and to fixate said blank during forming of a head on the blank. The invention further relates to a use of the aforementioned tool. Nails with offset heads are used in nail guns, where a strip of nails is used for shooting multiple times before reloading a new strip of nails. Novel and inventive aspects of the tool according to the invention comprise that the reception opening comprises a protruding section by the top side for forming an impression in the shank of said nail, said impression being placed adjacent to the head and mainly to a side, which is opposite the direction in which the head is to be offset, and that the protruding section comprises at least one substantially flat or convex surface for forming at least one substantially flat or concave section on said nail, said flat or convex section being placed substantially parallel to the longitudinal axis of the reception opening. In this way, a high strength is provided of the nail in the transition between the shank and the head.
