Abstract

1463273 Heading NATIONAL PLANT HIRE (PTY) Ltd 7 Jan 1975 [25 Jan 1974 25 Feb 1974] 629/75 Heading B3H [Also in Division F2] To form the head of a roofing nail with an annular recess 3 on its underside and a central protrusion 4 on its upper side, a bar 20 is gripped between two parts 21, 22 of a split die so that an end 23 projects above the die, and a punch 24 having a shaped recess 25 in its underside is brought down to deform the end 23 to form the head, the annular recess 3 being formed by an annular protrusion 27 on the die. The punch stops short of the die to leave a gap (26) (Fig. 6, not shown).
