  • the invention also relates to a device for producing packs for products of the cigarette industry, a group of products from the cigarette industry being wrapped as pack contents preferably on all sides in a packaging material and where folding flaps of the packaging material are connected to one another by forming seams, according to the preamble of claim 27 .
  • the production of packs of cigarettes is known from practice, a group of cigarettes being arranged in an envelope made of a sealable film material and the film material being closed by forming seams in order to create a so-called sealing block in which the cigarettes can be safely stored. It is known by sealing the seams To form or close layers of the film material. It is also known that the seams can be sealed against the cigarette group by sealing overlapping folding flaps of the film material or as so-called fin seams without the pressure required during sealing acting on the overlapping layers of the film material on the cigarette group.
  • Packs of this type have basically proven their worth. However, in some markets or countries there are regulations that regulate the materials with which the cigarettes may come into contact as pack contents. In particular, it is not allowed in such countries that the cigarettes are allowed to come into contact with coated materials and / or sealing media (e.g. varnish, glue, glue, etc.). The use of known packs of the type mentioned at the outset is therefore not possible, or only to a limited extent, in such countries.

  • the invention is based on the object of further developing packs of the type mentioned at the beginning, in particular with regard to an at least partial elimination of the problems present in the prior art, but at least with regard to the creation of further embodiments. Furthermore, the invention is based on the object of proposing suitable methods and devices for producing such packs.
  • a pack to achieve this object has the features of claim 1. It is accordingly provided that preferably all the seams are formed by crimping folding tabs of the packaging material that rest against one another in the overlap area of the folding tabs that rest against one another.
  • This procedure also has the advantage that the use of coated materials or sealing media can at least for the most part be dispensed with.
  • the production of the packs is thus easier, cheaper and more environmentally friendly.

  • a special feature can be that parallel to one or each seam a crease is made in the overlap area of the packaging material.
  • This solution can in particular have the advantage that when the seams are folded over, the overlap area having the seam is exposed to lower forces due to the grooving. This has a positive effect on the durability of the seam formed by crimping. It can preferably be provided that the grooving extends parallel to an adjacent seam and is arranged on the side of the adjacent seam facing the package contents.
  • the seams are arranged in such a way that the number of folding flaps lying against one another in the overlapping area and to be connected to one another by crimping is limited, preferably to less than 5 layers and most preferably to less than 4 layers.

  • the crimping is interrupted along a section of a seam in an overlapping area of the packaging material, and that this interruption of the crimping is arranged in the intersection area so that the crimps do not overlap in the intersection area.
  • the crimping is modified in an overlapping area of the packaging material, in particular with regard to a density of the crimping and / or an alignment of the crimping, and that a correspondingly modified section of the crimping is arranged in the intersection area.
  • the crimping is arranged in such a way that it does not cross the or each crease made in the packaging material, in particular such that the crimping ends before the or each crease and is interrupted in the area of the or each crease.
  • Another special feature can be that the areas of the packaging material facing the package contents consist exclusively of paper, or that the packaging material consists exclusively of paper.
  • the group of products from the tobacco industry wrapped in the packaging material forms an inner pack which is received in an outer pack, wherein the outer pack can preferably be designed as a hinged lid pack.

It is accordingly provided that preferably all the seams are formed by crimping folding tabs of the packaging material that rest against one another in the overlap area of the folding tabs that rest against one another.
  • the group of products is fed along a pack path and at least partially wrapped in a continuous material web of packaging material, and that one continuous seam is formed parallel to the transport direction for connecting two folding tabs of the material web by crimping, which is preferably directed transversely to a longitudinal axis of the group of products.
  • the continuous material web is subsequently severed between successive groups of products, with at least one provisional seam being formed by crimping, which runs transversely to the transport direction, preferably parallel to a longitudinal axis of the groups of products.
  • a provisional seam is formed on both sides of the separating cut by crimping.
  • final seams are formed by crimping, which run parallel to the provisional seams but are arranged closer to the group of products than the previously applied provisional seams.

  • corner areas of the packaging material are folded in the transition from narrow sides to the front side and in the transition from narrow sides to the bottom side.
  • a crease is applied in the overlap area, preferably simultaneously with the application of one or each seam, for later folding of the overlap area along the crease. Furthermore, it can be provided that the overlapping areas folded along the grooves are attached to the blank by means of gluing.
  • a device for solving the problem mentioned at the beginning has the features of claim 27. It is accordingly provided that preferably all the seams are formed by crimping folding tabs of the packaging material that rest against one another in the overlap area of the folding tabs that rest against one another by means of a crimping device.
  • the crimping device has two crimping rollers which are arranged on different sides of the folding tabs of the packaging material to be connected and between which the multilayer packaging material is passed for applying the crimping, the crimping rollers having corresponding crimping projections and crimping depressions for applying the crimping have mutually facing peripheral surfaces.
  • At least one crimping roller has a section in whose area the crimping projections and crimping recesses are interrupted in order to generate interruptions in the course of the crimping.
  • At least one crimping roller in addition to the crimping projections and / or crimping recesses, has means for the simultaneous application of a creasing on the packaging material, in particular a preferably circumferential creasing projection and / or a corresponding creasing recess.

Since the provisional longitudinal seam does not have to guarantee a permanent closure of the sheath 13, the individual crimping areas are arranged at a distance from one another.

Since the transverse seam is folded before the longitudinal seams are formed, four layers of the packaging material have to be penetrated during crimping in the overlapping area of the transverse seam with the longitudinal seams. The two layers of the transverse seam are also already crimped. Under certain circumstances, this can lead to incorrect seam formation. The applicant has recognized this and has therefore developed several solutions to this problem:
  • a first solution according to FIG. 14a is such that a crossing of the longitudinal and transverse seams is avoided. It is accordingly provided there that the transverse seam ends shortly before the longitudinal seams.

  • FIGS. 18 and 19 show a variant of the pack 10 or envelope 13 shown in FIGS. 1 and 2. First of all, it is noticeable that in the exemplary embodiment shown in FIGS. 18 and 19 the collar 27 shown in the exemplary embodiment according to FIGS is missing.
