Definitions

  • the invention relates to a method for producing a half-tube web according to the preamble of the main claim.
  • a disadvantage of this known method is the fact that during the production the prey is isolated and separated by cross-sealing. They are then collected and placed on a holding device.
  • the invention has for its object to design a generic method according to the preamble of the main claim so that a coherent semi-tubular web can be obtained continuously, the further processing by transverse sealing to the feed direction and filling and closing the bag filled in this way in the area of the second longitudinal outside edge should allow.
  • the cutting of the tape into the bag width and the connection of the cut tapes is achieved without the need to separate the bags.
  • the semi-tubular web can also be stored in a roll or zigzag shape and is in this form for further processing at the manufacturer of the product, the latter of which is to be packed into the prey.
  • 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, which runs 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 produced in this way 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.
