Definitions

  • the invention relates to a bag according to the preamble of claim 1 and a method and an apparatus for producing the bag.
  • the bottom is provided with a carrying handle.
  • the ends of the handle can be glued by means of tabs to the ground; a sheet may also be glued over the carrying handle, which is provided with a pre-punched opening through which the carrying handle protrudes.
  • the open projecting handle can be particularly annoying when storing the filled bag.
  • the leaves in the EP 0 553 693 A2 production of the bag described an automated production not.
  • a bag is known, on whose bottom a cover sheet is attached. Through two incisions in the cover sheet a carrying handle is formed. This embodiment requires a cover sheet of very stable material. Furthermore, between the carrying handle and the bottom of the bag no sufficient space for engagement of the user's hand is provided.
  • a bag which is provided with a carrying loop for carrying the filled bag.
  • a carrying device is provided with a handle, which serves to hold the bag during a Browntddling.
  • the invention has for its object to design a bag of the generic type so that the handle does not interfere with storage, but is easily accessible and can be provided in the region of its provided with the handle bottom with the necessary labels, and a method and a Specify device for producing this bag.
  • This object is achieved in a bag according to the preamble of claim 1 by the features in its identification part.
  • the carrying handle is hidden under the cover sheet, so it does not interfere with the storage of the goods.
  • the cover sheet can be printed closed with a necessary label, which can be attached twice, so that - no matter which side of the bag is stored - the title block is readable. There is enough space for a label. By simply tearing the cover sheet in the area formed by the perforation of the handle is accessible.
  • the method of claim 3 is a very simple solution according to the invention again, as the carrying handle can be made with cover sheet itself and attached to the bottom of a prefabricated unfilled bag.
  • Claim 6 represents a particularly advantageous simple device that can be associated with an existing bag manufacturing device.
  • the package shown in Figs. 1-5 is a bag 1 for packaging purposes, preferably a paper bag with gussets 2 closed at one end with a bottom 3 which is one Log soil acts. Of course can also be provided a cross bottom, in which case no gussets are present.
  • the bottom 4 shown in the drawing below is still open after the production of the bag 1 and is closed only after the bag 1 has been filled.
  • the closed bottom 3 is covered with a cover sheet 5, below which a strip-shaped carrying handle 6 made of tear-resistant paper, thin cardboard or plastic is arranged on the bottom 3. This carrying handle 6 is glued in the region of its ends 7, 8 with the bottom 3 and optionally with the cover sheet 5.
  • the cover sheet 5 is provided with two parallel to the longitudinal edges 9, 10 of the handle 6 extending cross-sections 11, 12 and a central connecting this optionally continuous longitudinal perforation 13.
  • the transverse cuts 11, 12 may also be formed by longitudinal perforations. Thus, it is about partial or complete severing of the cover sheet 5. If the cover sheet 5 is torn along the longitudinal perforation 13 and optionally of transverse perforations, then two cover sheet sections 14, 15 are formed, which can be folded up, so that the carrying handle 6 is exposed and can be pulled up through the cover sheet 5. 2, the carrying handle 6 is provided in its middle region with a Z-fold 16, which is opened when the carrying handle 6 is pulled out, so that the carrying handle 6 can be pulled out sufficiently high. The Z-fold 16 thus forms a memory fold.
  • the cover sheet 5 may be provided with two printed fields 17, 18, wherein the imprints may be identical but 180 ° rotated against each other, so that regardless of how the filled and sealed at the bottom 4 cuboid bag 1 in a shelf 19 as shown in FIG 5, the relevant contents are legible.
  • a device 20 for preparing the cover sheet 5 of the carrying handle 6 has a first machine frame 21, in which a first unrolling device 22 is supported.
  • a first roll 23 is mounted with web material made of tear-resistant paper, thin cardboard or plastic film, wherein the wound on the roll 23 web 24 has a width a, which corresponds to the total length of the carrying handle 6 including its ends 7, 8 (see FIG. 8th).
  • the web 24 is passed through a folding device 25 in which it is provided with a longitudinal fold for producing the Z-fold 16.
  • first cross cutter 28 cuts from the web 24 the already provided with the Z-fold 16 carrying handles 6 according to their predetermined width b. Adjacent carrying handles 6 are still connected to each other by means of small webs after cutting, so that the composite of the web is still preserved despite the cuts performed.
  • the first cross cutter 28 is in the conveying direction 29, a second Switzerlandwalzen pair 30 as a second preferred device immediately downstream, by means of which the still continuous web 24 is further transported.
  • a second unrolling device 31 is supported, in which a second roll 32 is mounted with a second web 33 of paper, from which the cover sheets 5 are cut.
  • the width c of the second web 33 corresponds to the length of the cover sheet 5.
  • the second web 33 is passed through the printing unit 34, in which the printed fields 17, 18 are printed.
  • the second web 33 is passed through a perforation device 35, in which the longitudinal perforation 13 is generated.
  • two adhesive nozzles 36 are arranged, are applied to the second sheet 33 - preferably clocked - adhesive strips 37 of hot or cold adhesive.
  • a pair of rollers 38 is provided, by means of which the second web 33 is deflected.
  • the upper roller 38 'of this pair of rollers 38 is segment-shaped, so that it detects only one carrying handle 6 in one revolution and tears off the web 24 and at the same time presses onto the adhesive strips 37 on the web 33.
  • the carrying handles 6 are thus placed at a distance from each other on the second web 33, which corresponds to the width of the cover sheets 5. At the same time, it also serves as a separating device. It should be added that the basic speed of the web 33 is naturally greater than that of the web 24, since the cover sheets 5 have a greater width in the conveying direction 29 than the carrying handles 6. The tearing off of the carrying handles 6 from the web 24 by means of the segment-shaped roller 38th 'So while simultaneously accelerating the carrying handles. 6
  • a third pair of draw rollers 39 connects to the pair of rollers 38 as a third preferred means, by means of which the second web 33 is withdrawn from the roller 32.
  • the already occupied with the handles 6 track 33 is fed to a second cross cutter 40.
  • the longitudinal cuts 11, 12 are produced in the second web 33 and then the cover sheets 5 are cut. Also in this case, the separation of the cover sheets 5 from the second web 33 is not yet complete. They are still small with this Webs connected. If, instead of the transverse cuts 11, 12 transverse perforations are to be provided, they can also be produced transversely to the conveying direction 29 with the cross cutter 40.
  • the cross cutter 40 is followed by a fourth draw roller pair 41 as a fourth preferred device.
  • the transfer device 43 consists essentially of a transfer roller 44 and a pressure roller 45 arranged above it, which like the roller 38 'is segment-shaped.
  • the transfer roller 44 and the pressure roller 45 are driven at a higher speed than the web 33, so that the covers 5 provided with the carrying handles 6 are finally torn off the web 33 and transferred to the transfer roller 44 at a distance from one another.
  • the transfer device 43 therefore simultaneously serves as a separating device for the cover sheets 5 with carrying handles 6.
  • the transfer roller 44 is formed in a known manner as a vacuum roller, that is, the blanks of the provided with the carrying handles 6 cover sheets 5 are held by acting from the interior of the transfer roller 44 negative pressure on the surface of the transfer roller 44.
  • a gluing unit 47 in which both the respective cover sheet 5 and the handle 6 are provided with an adhesive layer 48 which does not extend over the area which relates to the removable during use of the cover sheet 5 after tearing open the perforations 11, 12, 13 part of the carrying handle 6.
  • This transfer roller 49 is part of a stacking device 50.
  • This per se known stacking device 50 has a second machine frame 51, which is provided with a pair of cooperating feed belts 52, 53, by means of which those of the manufacture coming to be finished bag 1 of the transfer roller 49 are supplied, on which they are gripped by a gripper bar 54 and guided in the direction of rotation 55 by a feed 56 for the cover sheets 5 with handle 6.
  • the transfer roller 44 and the transfer roller 49 move in the same direction due to their opposite directions of rotation 46, 55.
  • the carrying handle 6 Since the blank of the cover sheet 5 has been rotated on the transfer roller 49 by 180 °, the carrying handle 6 is now at the bottom of the cover sheet 5. At the feed point 56, the cover sheet 5 is pressed onto the bottom 3 of the bag 1, whereby the cover sheet 5 and the ends 7, 8 of the handle 6 are glued to the bottom 3. For the described reasons, the carrying handle 6 is now between the bottom 3 and the cover sheet 5. The located between the ends 7, 8 area of the handle 6 is naturally not glued to the bottom 3 or with the cover sheet 5. Subsequently, the bag 1 provided with the cover sheet 5 and the carrying handle 6 is deposited in a stacking magazine 57 of the stacking device 50.
  • the printing of the second web 33 can of course also be done before the described method, so that already a printed second roll 32 is used. In this case, a printing unit 34 is not required.
  • control of the entire apparatus is carried out with measures generally used and known in continuous paper processing.
