Abstract: In an apparatus for and method of depositing adhesive strips, a ribbon including a layer of adhesive is directed along a predetermined input path. In the first two embodiments, the ribbon is engaged between a measuring roller and a driven roller responsive thereto, and fed into positioning structure. The material on which the adhesive is to be deposited is located between the positioning structure and a head, which can be heated. Separation means is provided adjacent the input path for selectively separating at least a portion of the ribbon to form adhesive strips, after which the strip of adhesive, the material and the head are engaged to effect deposition of the activated adhesive strip onto the material. In a third embodiment, the ribbon is engaged by a feed pulley and directed toward a revolving wheel rotatably interconnected with the feed pulley.

Abstract: 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.
