Abstract: A method of bundling bags by heat-adhesion comprising the steps of: making holes in bags made of heat-adhesive material; inserting guide rods into the holes of the bags to stack the bags at the correct position; pressing a heated thermal cutter against one end surface of the stacked bags to bond them together by heat-adhesion. Said guide rods are moved in synchronism with the feeding of the bag so as to be inserted into the holes formed in the bag. Said guide rods are inserted vertically slidable through bag holding cylinders having vertical grooves, the guide rods are provided at their top ends with arrows, those rear ends of the arrows that project from the side of the guide rods are hooked on the peripheral edges of the holes of the bag, and as the guide rods are lowered, the rear ends of the arrows are slid downwardly through the grooves of the bag holding cylinders to force the bag down the cylinders.

Abstract: A machine is disclosed which is intended to apply a saw-toothed blade to containers (for example of cardboard) which hold a coil or roller of aluminum foil or plastics material film of the kind used, for example in the kitchen or household in general. The saw-toothed blade must slightly protrude from the bottom front edge of the container to enable the user to tear out the portion of foil or plastics sheet to be used from time to time. The machine comprises a station in which the saw strips are severed from a metal tape and are applied to the flattened container, the latter being conveyed to the station by a conveyor belt assembly. The machine is equipped with appropriate cam and lever controlling and synchronizing means to have all the operative steps performed in the correct sequential order: the machine is compact and easily inspectable by one operator and the feeding means are all located on the longitudinal central axis of the machine.

Abstract: Panels of plastic film are delivered to a perforated vacuum drum which has a knife edged die mounted on its surface. Each panel is laid over the die and rotates with the drum into rolling contact with an anvil roll which firmly presses the film panel against the knife edge to cut the panel. After cutting, the film panel continues to rotate with the drum to a position wherein it registers with a blank having a cut-out opening therein which is covered by the film panel. The areas of the blank surrounding the cut-out opening are covered with an adhesive material which causes the film panel to remain adhered to the blank. The vacuum drum continues to rotate and, after bonding of the panel to the blank, the drum releases the vacuum draw on the panel. The cuts formed in the plastic film panels can be straight lines, lines of perforations, or cut-outs bounding areas which are removed from the panel.

Abstract: A method of arranging connecting material such as a suitable adhesive hot melt material in patterns on corrugated boards and assembling of pallets with legs at a remote site. The sheet or sheets of corrugated material are assembled by attaching the sheets singularly or in spaced apart juxtaposition to legs with connecting material therebetween. The connecting material may be first placed on each sheet in patterns for attaching the prismatic or tubular legs and then the sheets and prismatic or tubular legs are pressed together. The assembling device includes a central forming position and one or more stacking areas. The assembling device also includes connecting material activating means or connecting material supply means, stacking means, and press means. The stacking means receive the prismatic or tubular legs and at least one corrugated sheet for relative positioning. Each stacking means moves the sheets and legs into the central forming position for attachment purposes.

Abstract: An improved water mattress can be fabricated by a method which involves folding a rectangular sheet of thermal plastic material into a smaller rectangular sheet to form a dual-layered sandwich having three open edges; thereafter lap-sealing these three open raw edges to form a flat closed envelope, open at its corners; subsequently cutting specific sized rectangular notches in each corner of the envelope whereby the several apexes of each notch can be separated to form an overlapping slit which is reinforced with a separate piece of vinyl that is integrally bonded with the laps of the slit while it is in its stretched condition to completely seal the mattress.

Abstract: A length of face sealing valve stock is formed into individual face sealing valves and applied to end closures of pressurized dispensers. The stock advances in steps by a feed dog in vent slots in the tape. The tape is held against advancement by an index dog at all other times. Lost motion in the feed dog drive accommodates the drive to tape arrest and permits shutdown and startup at a known, predetermined position in a cycle. A head carries a punch and shear blade which form vent slots and cut the tape to valve length during the time that the tape is stopped. Tape is sheared to valve length at an index wheel which holds the tape by vacuum during shear and successive 90.degree. transports for solvent activation of adhesive and transfer from the wheel by bonding the activated adhesive to an end closure. A proximator forces an end closure into contact with a valve during transfer.

Abstract: Adhesive joining system for joining a plurality of superimposed material layers. An elongated needle-like member is reciprocally and rotatably driven along and about its longitudinal axis so that each reciprocation causes the needle to pass through and be withdrawn from the superimposed layers. After the needle has passed through the layers, at least the outer tip is coated with an adhesive material. The adhesive material itself may be in solid, liquid or powdered form and be either heated or unheated. After coating, withdrawal of the needle from the material layers causes the adhesive on the needle to be deposited on the material through a wiping action caused by the pressure of the material exerted against the needle. Rotation of the needle-like member gathers loose fibers from the material layers and wraps them together in the adhesive to form a reinforced joint.

Abstract: A method and apparatus for slitting a moving thermoplastic film. A rotating slitting roll, provided with a plurality of spaced-apart heated blades circumferentially arranged in a pattern, presses the film against a backing member while the film is under tension and in line-contact with the roll. The pressure and heat of the blades fusion-slits the moving film, which may then be stretched to spread the slits and in the case of orientable film to orient the film in the direction of stretch. The slits may be made in either the machine or cross-machine direction. Where continuous slits are made, tapes or ribbons are formed. Where the slits are discontinuous, an aperture film results.
