    Abstract: The present invention encompasses principally a method of permitting packaging of one or more piece goods in one or more bag units, where said bag units are, in a selected transport direction, oriented after one another and mutually united with the aid of two, each arranged bag side allocated, thickened portions. A first means (1) is disposed whereby each one of said bag units, from a folded and/or united state, becomes openable by causing said respective bag side allocated thickened portions to pass along a distance from one another oriented rails or similar arrangements. A second means (2) is disclosed in order to, in thus opened bag units, allow insertion of one or more piece goods (G). A third means (3) is utilized, whereby each one of said bag units is sealed along a sealing zone, in order thereby to allow the enclosure of said one or more piece goods. A fourth means (4) is adapted to clip and/or cut off a sealed bag through or above said sealing zone, however under said thickened portion.

  • Patent number: 5080747
    Abstract: Heated seal bars are located on opposite sides of an elongated strip of heat sealable material adapted to be advanced with a step-by-step motion. When the strip dwells, the bars are shifted linearly inwardly into engagement with the strip to form a heat seal and then are retracted linearly a short distance away from the strip to permit the strip to advance through its next step. If an abnormal condition prevents the strip from advancing, the bars are retracted linearly to a parked position in which the bars are spaced a substantial distance away from the strip in order to prevent the heat radiating from the bars from damaging the stopped strip.

  • Patent number: 4838977
    Abstract: To make plastic carrying bags or sacks, sections are cut or are severed by hot wire welding from a gusseted tubular film by a formation of transverse seam welds and transverse severing cuts or by hot wire-welded transverse seam welds. At least in their bottom portion the sections are provided with corner seam welds, which are separately formed in the two folds and which diverge obliquely from the outer fold lines toward the top and/or bottom seam weld and terminate short of the inner fold line and merge into the latter. To prevent in the making of the carrying bags an elongation of the intermediate portion of the tubular film, the latter is initially formed with corner seam welds only in one fold of each of the two gussets before the transverse seam welds and transverse severing cuts or hot wire-welded transverse seam welds are formed. When said corner seam welds have cooled, congruent corner seam welds are formed in the respective other folds.

  • Patent number: 4698112
    Abstract: An apparatus for producing various shapes of polyethylene bags includes a heating mold separating means, a cutting mold separating means and a collecting means. By using such an apparatus for making PE bags, a double-layered polyethylene sheet rolled on a roller is transported into the heating mold separating means by input rollers to form polyethylene bags of any desired shape. Since the bags can not be completely separated from the sheets by heating mold, the bags together with the sheets must be sent into the cutting mold separating means by transporting rollers again. The cutting mold separating means will cut the boundary of the bag except the root portion, so that the bag is completely separated from the sheets, except for the root portion. Finally, the bags together with the sheets are sent into the collecting means. The cutter of the collecting means indents the root portion of the bags and the needles of the collecting means pokes through the root portion of the bags.
