Definitions

  • the invention relates to a method for producing a half-tube web according to the preamble of the main claim.
  • the semi-tubular web is produced and at the same time the tapes, cords, cords or the like are continuously attached in pockets on the top and bottom of the longitudinal outer edge.
  • the individual bags are then sealed transversely to the feed direction, the bags being pulled apart in order to have the required amount of tape for the subsequent knotting process. Then the ends of the tape are knotted.
  • the finished individual bags are then collected on holding tubes in the area of previously punched holes.
  • a disadvantage of these known methods is the large amount of tape that is required for knotting. Furthermore, the procedure is due to the knotting slowly. Finally, it is necessary for the knot to make and separate the bags. Then manual gathering and plugging is required, quite apart from the fact that thick tapes can only be inserted manually, or instead a separate part must be welded in the area of the first longitudinal outer edge.
  • the invention has for its object to design a generic method so that a coherent semi-tubular web can be continuously obtained, the further processing of which is to be made possible by separating sealing and filling and closing the bag filled in this way in the region of the second longitudinal outer edge without having to after Separating the bags requires a knotting process. It should also be possible to process thick strips.
  • the semi-tubular web can be stored in roll or zigzag form and is in this form for further processing at the manufacturer of the product which is to be packed in the bags. Furthermore, there is considerable material savings on the belt because this is only required in the exact width of the bag.
  • a separate punching can also be provided between two mutually adjacent punched-out parts, with the interruption of the first longitudinal outer edge, so that at this point the band can be pulled out for use as a carrying loop, which can be used to carry the bag in pairs or via the Shoulder allows.
  • FIG. 1 shows a deflection roller, generally designated 5, around which the semi-tubular web, generally designated 7, is guided in the feed direction 6.
  • the semi-tubular web is provided with an inward running fold 9 on the first longitudinal outer edge 8.
  • the other of the two second longitudinal outer edge 10 running parallel to the first runs on the open part of the half-tube web 7.
  • individual welding spots (21) are attached in order to attach the two parts of the half-tube web together.
  • parts 12 of the semi-tubular web 7 are punched out in a semicircle at a distance of a bag width 11 (FIG. 2) together with separate rectangular punched-outs 13 in between such that the first longitudinal outer edge 8 is also interrupted.
  • the semi-tubular web 7 thus produced is continuously rolled up or zigzag-shaped placed in a container without separating the individual bags and this container or the roll is transported to the user, where the separation and filling of the separated bags from the side of the second longitudinal outer edge 10 on which the bag is still open.
