In an apparatus and method for prefabricating pockets continuously, pocket material is directed lengthwise along a predetermined path. The pocket material is nipped between a feed roller and an idler roller for advancement first to an adhesive application station. In one embodiment, predetermined adhesive strips formed from ribbons comprising a layer of fusible adhesive on a backing are attached along the edges of the pocket material. If desired, a transverse strip of adhesive can also be applied. In the alternative, adhesive can be extruded directly onto the pocket material along the edges and transversely if desired. The pocket material is then advanced past a cutter and sheared to provide an individual pocket blank. The pocket blank is next aligned, after which the aligned pocket blank is transferred into position for transverse folding. In the preferred embodiment, the edges of the pocket blank having adhesive there along are folded inwardly simultaneously upon transfer. A movable blade then folds the pocket blank transversely and advances the folded pocket blank into one of a plurality of pocket receivers in a rotatable pocket wheel. As the wheel is indexed, the edges of the folded pocket blank are engaged and activated to permanently secure the edges and thereby form a pocket. The prefabricated pockets are then removed for subsequent implantation into a garment. |
