  • Patent number: 4264391
    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.

  • Patent number: 4259144
    Abstract: The invention relates to a tape applicator head for dispensing tape onto a working surface for the construction of primarily structural parts, and to a method of laying tape onto a working surface.The tape applicator head includes a housing which is preferably displaced relative to the working surface. The housing includes a tape dispensing outlet where at least one tape dispensing structure has a tape engaging surface which imparts a tension to the tape as the tape applicator head is displaced relative to the working surface to drive the tape through the tape head. Preferably, two tape dispensing blocks are mounted to the housing at the tape dispensing outlet adjacent to each other. These blocks define spaced, symmetrically oriented surfaces which alternately engage the tape and impart the noted tension thereto as the tape applicator head is displaced in two opposing directions relative to the working surface. With this latter arrangement, the orientation of the tape applicator head is maintained unchanged.
