Abstract: A device for dispensing an individual plastic fastener from a supply of fastener stock includes a motor-driven head assembly adapted to receive the supply of fastener stock, sever an individual fastener from the supply and in turn eject the severed fastener. The head assembly includes a pair of needle block assemblies that retain corresponding hollow needles, each needle block assembly being shaped to define a feed channel that transitions a side rail for the fastener stock into axial alignment behind its corresponding needle. In addition, at least one needle block assembly includes a rearward shelf and a forward bowing plate. In use, the lowermost cross-links of the fastener stock fittingly align between the shelf and the bowing plate. In this manner, the lowermost cross-links are limited to distort uniformly upward within the single plane defined by the pair of feed channels, thereby optimizing feed reliability of the device.

Abstract: Standard tag attaching fasteners in continuous strip form are intermittently moved toward an attacher along a guide track which gradually changes shape from planar to semicircular. The T-bars are feed to the attacher, which is mounted upright on a base. At the same time, each paddle, in turn, having traveled along the guide, is oriented in a plane perpendicular to the axis of the needle, at a location in alignment with but spaced from the needle. A tag or hook, previously removed from a stack by a moveable arm with a vacuum head, is in place over the needle. A portion of the article is situated between the needle and the fastener filament, with the needle in an opening or recess of the article. Upon actuation of the apparatus, the paddle is clamped in position and driven toward the needle such that the paddle is penetrated by the needle. The attacher then ejects the T-bar which lodges on the far side of the paddle, securing the ends of the fastener together to form a closed loop around the article.
