| 64 | Apparatus for making bags from a two-ply web of thermoplastic material | US816033 | 1977-07-15 | US4115183A | 1978-09-19 | Fritz Achelpohl; Friedhelm Mundus |
| An apparatus for making bags from a continuously fed heat-sealable web comprises supporting bars for the web arranged on a rotary cylinder parallel to and at a spacing from one another. Means for transversely welding and separating the web comprise welding bars co-operating with backing bars. The backing bars are arranged between the supporting bars and are displaceable towards the welding bars. The supporting and backing bars are movable towards and away from one another in a zig-zag line during transference of the web passed therebetween. The supporting bars for receiving and holding the web are axially extensible and retractable at least over the width of the web. In the region of the cylinder sector in which the supporting bars are retracted and the separating weld seams are produced, the welding bars are guided to be concentric with the cylindrical enveloping surface swept by the backing bars, namely outside said enveloping surface and at the same angular speed. | ||||||
| 65 | Apparatus for making bags from a continuously fed thermoplastic tubular web of film | US785697 | 1977-04-07 | US4114520A | 1978-09-19 | Fritz Achelpohl; Friedhelm Brinkmeier |
| In an apparatus for making bags from a continuously fed flattened thermoplastic tubular or semi-tubular web of film, severing means for cutting the web into sections co-operate with a first welding cylinder for performing a welding operation on each section with the aid of welding tongs, the web sections being held to the welding cylinder by means of belts which partially envelop the cylinder, and a second welding cylinder is provided downstream of the first cylinder, the web sections being transferred to the second cylinder for the purpose of having a further welding operation performed on them. | ||||||
| 66 | Bottom seal cut-off | US240075 | 1972-03-31 | US4101369A | 1978-07-18 | Richard C. Adams |
| Thermoplastic web treating apparatus, particularly adapted for the fabrication of flexible bags and comprising, in combination, a web treating station along with means for intermittently advancing webs through the station. The treating station includes thermal welding or sealing apparatus with a welding bar and sealing pad combination for forming spaced seals in the web, and a cutting blade for cutting or shearing the web. The apparatus is designed to provide tension during cutting operations, and to eliminate tension prior to and during sealing operations to permit "relaxation" of the film prior to formation of the seal, as well as to break away any bond which may form between the thermoplastic web and the sealing pad from the sealing operation. This break-away of the bond is accomplished through an initial short duration reversal of the web draw rolls prior to each web advance. | ||||||
| 67 | Apparatus for processing a web of material without a standstill | US703934 | 1976-07-09 | US4061458A | 1977-12-06 | Friedhelm Mundus; Horst Schneider |
| A continuously travelling web of material is processed at longitudinal intervals between a pair of confronting transverse processing tools. The tools are mounted on carriers guided in pairs on endless chains to follow a path composed of two parallel straight sections joined at the ends by semi-circular sections, the latter being relatively adjustable. The chains are guided on adjustable sprockets so that their runs are parallel and overlap. Confronting extensions of interconnecting hinge pins for the links of the chains are engageable in recesses provided in the tool carriers. | ||||||
| 68 | Apparatus for bonding layers of resinous material | US665723 | 1976-03-10 | US4059478A | 1977-11-22 | Louis S. Hoffman |
| A method and apparatus for bonding at least two films of resinous material such as polyester films to one another wherein at least a portion of one surface of one polyester film is placed contiguous with at least a portion of one surface of the other polyester films adjacent thereto. At least one layer of resinous material such as a layer of polyester is placed adjacent each of the other surfaces of the polyester films to be bonded and opposite the contiguous portions of the surfaces. The contiguous portions of the polyester films to be bonded are compressed against one another by pressure applied to the two outermost layers of polyester. The temperature of the contiguous portions along their interface is raised at least to a bonding temperature of the polyester by energy transmitted through the layers of polyester on each side of the two polyester films. When the energy, and subsequently the pressure, are removed from the polyester films, a bond is formed between the contiguous surfaces of the polyester films. | ||||||
| 69 | Pad-stacked bags or similar packaging, and apparatus and method for fabricating the same from plastic film | US567073 | 1975-04-10 | US4046257A | 1977-09-06 | Hans Lehmacher |
| Thermoplastic film bags or like packaging sections with or without hanger holes are stacked and welded into pads from which individual bags are easily hand-torn for use. Bag sections, each with a hanger portion and having an arched cut in one wall, are produced three at a time from a continuously longitudinally sub-divided and side seam welded, wide flattened film tube stock web, after incising the cuts at three transversely spaced places in one layer; the sections are stacked and at the hanger parts welded into a pad, and the pad is transversely perforated through the incised arched cuts and hanger holes punched in the hanger part. | ||||||
| 70 | Apparatus and method for forming pouches | US549462 | 1975-02-12 | US4002519A | 1977-01-11 | Ronald E. Moseley; Henry G. Stewart |
| Successive pouches are formed from a web of plastic film by advancing the web through a folding station and folding the web along a longitudinal fold line to form a two-ply portion and a single ply portion adjacent thereto. At a sealing station, confronting surfaces of the two-ply folded portion of the web are sealed together along longitudinally spaced apart seal areas extending transversely across the two-ply portion to define a series of successive pouches interconnected by the seal areas. At a flap forming station predetermined waste areas are severed and removed from the single ply portion of the web to form the same into a series of successive flaps extending alongside each of the pouches and adapted for being folded over the pouches to close the same. The predetermined waste areas are quickly severed and removed by first piercing the single ply web at a predetermined point spaced from the free longitudinal edge thereof and corresponding to one end of the waste area, and then severing the single ply portion from the point of piercing along two spaced apart cut lines extending to the free longitudinal edge thereof. The waste area is graspingly engaged closely adjacent to the free longitudinal edge during severing to facilitate severing the waste area free from the remaining web, and is thereafter ejected clear of the advancing web by a blast of air. After heat sealing and flap formation, the web is advanced to a cut-off station and successively severed transversely across the folded web and across a medial portion of each seal area to separate the interconnected pouches from one another. | ||||||

| A bag structure of the flap type wherein the flap is tack heat-sealed for ready opening by virtue of heat-sealing webs together, wherein the heat-seal overlies a coating substantially resistant to union with thermoplastic material when the latter is in a molten state. | ||||||
| 72 | Method and apparatus for manufacture of pad-stacked bags | US282193 | 1972-08-17 | US3966524A | 1976-06-29 | Hans Lehmacher |
| Sections successively severed from a double layer web of synthetic thermoplastic film, e.g., flattened tube stock, as produced are each stacked and welded to a precedingly stacked section near one edge of a tear off pat or hanger portion to which a bag portion of the section is attached; forming ultimately a pad of bag sections, wherein each section includes either a completed bag or a partially completed bag, in the latter case with final bag producing operations carried out simultaneously for all bags already welded together in a pad structure. | ||||||
| 73 | Sterile pouch | US425306 | 1973-12-17 | US3938658A | 1976-02-17 | William A. Rohde |
| A pouch made from thermoplastic film and particularly suited for sterilizing and storing medical items has an edge defined by a fold of the film. A cap of porous material is wrapped over the folded edge and is sealed thereto along a continuous line to define an enclosed area on both sides of the edge in which the film and cap are unsealed. An opening, such as a slot, is provided in or adjacent to the fold of the film, with the opening being entirely located within the unsealed area and spaced from the seal line. The construction lessens the possibility of open bacteria paths often found in similar prior art pouches.In the manufacture of the pouch, a web of thermoplastic film is provided with a series of spaced linear openings or slits, a porous sheet material is applied over the openings and the porous material is sealed to the web along a continuous line surrounding the openings. The material is then folded along the line of openings, cut transversely into sections between the ends of the openings, and heat sealed along the sides to form a pouch having an opening at one end and a porous end cap at the other end. | ||||||
