ABSTRACT:
Apparatus for dispensing attachments from continuously connected ladder stock of the type comprising a pair of plastic side members coupled together by a plurality of plastic cross links includes a mount, a support movably mounted on the mount, and a pair of carrier blocks mounted on the support. A needle block is mounted on each carrier block and a hollow, slotted needle is mounted on each needle block. A feed mechanism including a pair of feed wheels, is mounted on said support for advancing the ladder stock into the hollow slotted needles and a pair of feed tracks, one for each hollow slotted needle, are provided through which the ladder stock passes from the feed wheels into the pair of hollow slotted needles. A pair of knifes are provided for severing an attachment from the ladder stock, and a pair of ejector rods are provided for ejecting the severed attachment through the hollow slotted needles. The carrier blocks are disposed parallel to each other and movable sideways relative to each other so that the spacing between the hollow slotted needles can be changed for different applications and the feed wheels are disposed parallel to each other and movable sideways relative to each other so that their spacing can be changed to accommodate different widths of ladder stock. In order to provide a path for the ladder stock from the feed wheels to the hollow slotted needles for different feed wheel spacings and/or needle spacings each feed track assembly includes a pivotally mounted section.
