Abstract
Abstract Method and apparatus for dispensing of attachments comprising a pair of side members linked by a connector. A roll of fastener stock is fed to a reciprocatively driven slide head assembly at which the roll is advanced over an elastomeric feed belt to a pair of needles secured to a shuttle. Once inserted in the needles, an individual attachment is severed from the stock, and displaced over a preset distance by the shuttle into the path of a pair of ejector rods. The ejector rods force the side members of the attachment out of the needles for insertion in a fabric or other workpiece at the bottom of the head stroke. On return stroke of the head, the needles are withdrawn, ejector rods retreat, and the shuttle returns to its severing position in a manner to avoid mechanical interference. This design uses an electric motor driven fastener dispensing head, actuator slide and associated linkages for actuating the various mechanisms either on an on-demand or continuous basis. Reliability is improved by severing the attachment stock in the needle, and transferring the severed attachment to its insertion location.
