ABSTRACT:
A tack for holding soft thin membrane-like materials such as roof shingles, roofing felt, or house wrap is produced in collated strips from a stock of band sheet metal. Each tack has a head and a shank lanced out of the head and bent out to leave behind a slot in the head. The shank of a given tack nests within the slot of an adjacent tack in a side by side relationship for collating in strips for use in a tacker tool. The production of the collated strips of tacks includes a progressive punch press operation wherein the stock of band sheet metal is indexed incrementally therethrough in a given indexing direction. At the extreme end of the progressive punch press operation, a completed tack is advanced to and through a collating operation in a given collating direction. In one example, the indexing direction and collating direction are arranged 135.degree. apart. The collating direction is generally co-axial with the alignment of the slot of the tacks as each is separated off the end of the stock band of sheet metal, such that, without rotating the tack, the shank of each tack can be nested in the slot of the preceding tack merely by advancing the tack in a straight line.
