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.

Abstract: Slitter-sealer, for slitting two layers of thermoplastic polymer film and sealing the slit edges of adjacent layers together, has a preheater for preheating the polymer film before slitting to reduce the required temperature at the slitter and improve sealing.

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.

Abstract: This relates to a device for pinching off a length of a continuous tube and heat sealing the same, together with a cutting off of the closed end tube portion. A pivot is provided on which there is mounted a pair of blade like members each carrying a heat sealing member with the heat sealing members being cooperable both to flatten or pinch the tube and to heat seal together the pinched together portion of the tube. A blade element is also carried by the pivot and is cooperable with the heat sealing members to cut off the pinched and heat sealed tube portion. Plungers are provided for effecting the pivoting of the blade like members and the blade elements and the plungers are carried by guide sleeves which extend through a machine wall with there being on the opposite side of the machine wall suitable drive means for effecting the controlled reciprocation of the plungers.

Abstract: A vent for thin, flat laminar batteries comprising a paper strip enclosed along its length by a gas-permeable, liquid impermeable thermoplastic composition. One or more of the vents can be incorporated into a frame structure which also serves to provide internal and external sealing. For this purpose, the vents are sealed to frames comprising closed loops of thermoplastic material, dimensioned to correspond to the external and internal dimensions of the battery. Methods of making vents comprising the steps of laminating paper with a thermoplastic material and forming the laminate into thermoplastic tubes filled with a paper core.

Abstract: Structures are provided in attachment means for textile fasteners such as buttons and the like. In one form, a flexible thread or filament is secured between a fastener such as a button and textile material and is reinforced by means of a plastic material. A plurality of loops of the thread are secured together with a plastic which not only reinforces the thread but also serves to prevent its unwinding from the textile material and fastener. The reinforcing plastic may also be bonded or welded to the fastener and the textile material. In another form, the thread or filament is coated with or comprises a heat sealable plastic wherein a specially heated tool is employed to seal same to itself and in certain instances the fastener and the textile material.

Abstract: Apparatus for repairing sprocket holes on strip material, such as motion picture film, with pressure adhesive tape having holes, is provided with guide means for feeding material through a sprocket wheel at a repair station, and an improved means for pressure bonding repair tape on material at the sprocket wheel comprised of a sponge rubber pressure roller. Dual tracks and sprocket wheels are provided for use of the apparatus with material of different gauges.

Abstract: An apparatus and method for applying metal foil-plastics material film laminate pull tabs to coated container units. A high frequency electrical energy force field is set up and induced into the metal of the pull tab with the resultant heating of the metal and the subsequent heating of the plastics material film to a bonding temperature together with the application of a magnetic repulsion force to the pull tab urging it away from its supporting head and into forced contact with the container unit.
