Abstract
Abstract This apparatus includes a magazine for supporting a stack of hang tabs in flat condition and a reciprocating slide plate moves beneath the stack of hang tabs to successively remove the bottom hang tab from the stack and move the same to an adjacent folding station. A folding blade is supported for reciprocation in a vertical plane and moves down into engagement with the hang tab to fold the same medially and provide a pair of legs of substantially equal length into which the end of the zipper may be positioned by the operator. A staple head is supported beneath and in alignment with the folding station and a manual switch is provided for actuating the staple applying head to connect together the legs of the hang tab and to secure the end of the zipper therebetween.
