Abstract
A method and apparatus is disclosed for affixing heads to headless fasteners to form webs thereof, wherein the headless fasteners are equally spaced apart a given spacing. The web of headless fasteners is conveyed to and disposed so that each of a first set of headless fasteners is disposed in an aligned relationship to corresponding ones of a plurality of 'n' head affixing devices. The head affixing devices are spaced from each other a distance equal to the product of the given spacing and ('n'.+-.1). The plurality of head affixing devices are actuated to fasten 'n' heads to their aligned fasteners of the web. Thereafter, the web is moved with respect to the plurality of 'n' head affixing devices a distance equal to the product of 'n' and the given spacing to align each of a second, different set of fasteners of the web to corresponding ones of the plurality of 'n' head affixing devices. The plurality of the head affixing devices are actuated for a time period during which each of the present set of headless fasteners is maintained in the aligned relationship with its corresponding one head affixing device. The web is repeatedly moved and the 'n' welding devices are repeatedly actuated until a head is affixed to each headless fastener of the web.
