  • closure strips or closure seams extend over the full width of the bag.
  • the invention has for its object to propose measures for the production of bag packages, in particular for cut tobacco, which have a reusable closure of the bag opening of two opposing closure strips, the closure strips are sensitive or problematic with respect to the attachment of transverse sealing seams.
  • the method according to the invention consists of the features of the characterizing part of claim 1.
  • sections or pieces of closure strips produced immediately before application to a continuous film web are formed and positioned precisely, namely at a distance corresponding to the distance of the bags to be produced within the material web, corresponding to the position on the front wall and rear wall of the bag bag. This creates gaps in the area of the transverse or closure seams can be attached.
  • An apparatus for carrying out the method is formed with the features of claim 4.
  • the pieces of the profile strips are applied to the film in the region of the circumference of a roller and transported together with this in the region of a likewise formed as a roller heating station for connecting the portions of the closure strip with the film.
  • the embodiments of bag packages 10 serve to receive a tobacco portion 11.
  • the bag is made of thin packaging material, in particular of a thermally sealable film.
  • a blank is folded to form a bottom edge 12, so that a front wall 13 and a rear wall 14 are opposite each other or form the actual bag for receiving the tobacco portion 11.
  • front wall 13 and rear wall 14 are permanently connected to each other, by (upright) side seams 15, 16.
  • the rear wall 14 is provided with a continuation or continuation to form a flap 17, the closed wallet against the front wall 13th transferred and connected to this solvable, eg with an adhesive label 18.
  • An upper portion of the bag or front wall 13 and rear wall 14 is formed as a bag opening 19. This extends between the side seams 15, 16. About the bag opening 19, the tobacco portion 11 is filled and removed when consumed. In the closed position are upper edge strips of the front wall 13 and rear wall 14 to each other or are connected to each other by separable closure means.
  • the closure means or closure members may be formed in various ways.

  • the zip lock closure 60 consists of two profile strips 62, 63 which are internally connected to the front wall 13 on the one hand and the rear wall 14 on the other hand, in each case via upper and lower connecting seams 64, 65.
  • the second closure means is the sealing seam 61 which is easily detachable (by hand), in particular in the form of a peel seal.
  • the sealing seam 61 is attached above the zip-lock closure 60, adjacent to a free edge of the front wall 13. This can be detected when the bag package 10 is opened for the first time in order to separate the sealed seam 61. Thereafter, then the zip-lock closure 60 can be separated for the removal of the bag contents.
  • a feature of this bag package 10 is that the sealing seam 61 extends over the full width of the front wall 13 and rear wall 14, thus also in the region of the side seams 15, 16 to create a tight bag closure.
  • the profile strips 62, 63 and their connecting seams 64, 65 also extend over the full width of the bag.
  • a special feature is the shortened design of the zip-lock profiles 66, 67, such that they end with (small) distance from the side seams 15, 16.
  • Fig. 29 For this purpose, for example, a semicircular punching 68 in the profile strips 62, 63 attached to both ends, and substantially in the area of the zip-lock profiles 66, 67. In the region of the punched 68 and the recess formed thereby in the Profile strips 62, 63 are the bag walls, ie front wall 13 and rear wall 14, connected by the side seams 15, 16 directly by thermal sealing.
  • a special feature is the production of the package.
  • a continuous, in particular wound as a reel of material sheet 69 of thermally sealable film is provided.
  • This is provided in a first step, especially in the factory production, with suitably positioned seam strip 70, 71.
  • the seam strips 70, 71 have a significantly greater width than the sealing seam 61 to be produced later. Due to the greater width, inaccuracies in the application of the sealing elements or sealing jaws for producing the sealed seam 61 can be compensated.
  • the sealed seam 61 should lie approximately in the middle of the adjoining seam strips 70, 71.
  • the profile strips 62, 63 are placed on the material web 69 prepared in the above sense as a continuous belt 72 while being pulled off a reel.
  • the band 72 consists of the two profile strips 62, 63 which are interconnected in the region of the zip-lock profiles 66, 67 and thus together form the band 72.
  • Each profile strip is provided at appropriate intervals from each other in the present case circular punches to form the punched-68 at the ends of the profile strips 62, 63.
  • the tape 72 is after laying in the region of the material web 69 by making the front side seams 64 with the material web 69th or connected to the front wall 13.
  • the thus prepared material web 69 is then folded continuously to form the front wall 13, such that the seam strips 70, 71 are congruent to one another.
  • the transverse side seams 15, 16, namely correspondingly double-width seams are now attached.
  • This is followed by a cross-sectional cut in the area of the double-width side seams 15, 16, so that finished, open bag packages 10 arise.
  • the separation cut is carried out so that the closed, here circular hole punching in the region of the profile strips 62, 63 is severed centrally, so that the semi-large or semicircular punched at the ends of the profile strips 62, 63 arise.
  • the tobacco portion 11 is now introduced. Thereafter, the rear wall 14 facing profile strip 63 is connected to the rear wall 14, by attaching the two associated connecting seams 65.
  • the sealing seam 61 is then produced by applying heat and pressure in the adjacent seam strips 70, 71. The ends of the seam strips 70, 71 already (permanently) by the side seams 15, 16 connected to each other, which are produced with increased temperature and elevated pressure.
