Definitions

  • the invention relates to a jacket for a liquid-tight packaging made of cardboard and a heat-sealable, double-sided plastic coating, in particular aluminum-free composite material with a longitudinal seam, which consists of an inner layer of the composite material with an externally folded, sealed edge strip and an outer layer of the composite material is formed, which is sealed on the outside to the edge strip and the adjacent composite material including the cut edge of the edge strip.
  • the invention further relates to a method for producing such a jacket, in which the composite material is peeled before the edge strip is folded over and the outer layer is sealed to the edge strip and the adjacent composite material after it has been folded over to the peeled side and the edge strip has been sealed.
  • a difficulty in the manufacture of jackets for liquid-tight packaging from both individual blanks and a material web is in the production of the longitudinal seam, because due to the restoring forces of the composite material, in particular an aluminum-free composite material, it is not possible to fold exactly along a fold line without pretreating the composite material.
  • the invention has for its object to provide a jacket for a liquid-tight packaging made of cardboard composite material, which has a straight longitudinal seam and which can be produced with a less complex method using less complex tools than in the prior art.
  • the composite material in a narrow, on the The fold of the folded edge strip, which is limited and the inside of the folded edge strip, is where composite material has been removed, in particular burned or preferably peeled off.
  • the composite material is peeled in the area of the fold before the edge strip is folded over and after folding over to the peeled side and sealing the edge strip, the outer layer is sealed to the edge strip and the adjacent composite material, the composite material only worn in a narrow zone restricted to the fold.
  • the removal can e.g. Realize that the material is burned off on the surface by means of laser radiation.
  • the material is preferably removed mechanically by peeling. This peeling process can be implemented in a particularly simple manner if a raised bead running along the fold line is formed in the composite material, in particular by means of scoring, which is then peeled off.
  • the peeling is preferably carried out with a pot knife with the support of the composite material on a counter-holder engaging in the groove of the crease bead, which guides the crease bead centrally over the pot knife.
  • a suitable counterhold is a creasing roller.
  • a bead raised to the removed side should be formed in the removed zone after removal and before the edge strip is folded over.
  • the folding process and the subsequent sealing are unproblematic.
  • the peeling of the composite material in the entire area of the edge strip or beyond is eliminated, so that the use of expensive peeling or milling tools is unnecessary.
  • the jacket can be produced particularly easily if the raised bulge is produced before the peeling, which can be removed with a pot knife that is less complex than milling tools. Since the invention ensures that a straight edge is obtained even after the edge strip has been folded and sealed, the prerequisites for a precise production of the longitudinal seam are given.
  • the composite material used consists of cardboard and a plastic coating on both sides made of heat-sealable material, for example PE.
  • the basis weight of the composite material is between 200 and 250 g / m2.
  • An edge strip 4 of the inner layer 2 is folded outwards and sealed to the inner layer 2 on the outside.
  • the outer layer 3 is sealed both on the edge strip 4 and on the adjacent inner layer 2, including the cutting edge of the edge strip 4.
  • the composite material is weakened in a narrow zone by peeling the composite material on its surface.
  • a raised bead 8 is formed in the composite material 7 after the step of FIG. 2a, in that the composite material 7 runs through a pair of rollers 9a, 9b with a negative groove and a scoring disk.
  • the composite material 7 is fed to a revolving pot knife 10, the composite material 7 being fed centrally to the pot knife 10 by means of a roller 12 which engages in the groove 11 of the composite material 7 and serves as a counterhold and guide.
  • the composite material 7 is fed to a further pair of rollers 13a, 13b with a groove and a creasing wheel, which form a new raised bead 14 on the peeled-off side of the composite material 7.
  • This new bead 14 supports the folding process on the already weakened composite material 7 along the folding line.
  • the edge strip 4 is folded by means of a folding tool with a folding rail 15. Thereafter, the composite material 7 with the folded edge strip according to FIG. 2e passes through a further pair of rollers 16a, 16b, which brings about a pre-pressing.
  • the plastic coating consisting of PE coating is activated according to FIG. 2f, so that in the next method step according to FIG. 2g the edge strip 4 can be applied to the activated area of the composite material 7 in a further folding station with a belt guide 18a, 18b.
  • edge strip 4 is guided and pressed between a pair of rollers 19a, 19b according to FIG. 2h.
