  • a movable die which lays glue on lamell after lamell is used thereby.
  • the finished packaging material can be formed to the wished widths by different procedures:
  • the paths of material can be cut to the wished widths just before lamination against the distance material takes place.
  • the cutting can be made for example with a knife equipment. In this case the distance material has been prepared to the right width before it is fed in to the lamination machine.
  • the finished laminate can be cut to the right widths direct after the lamination machine before it is rolled or folded.
  • the finished laminate can be prepared to wished widths at a special machine unit, which is separated from the lamination machine.
  • the finished ' laminate can be rolled direct after the lamination machine as in figure 1. It can also be folded, with a useful equipment, direct after the lamination machine.
  • a special unit where rolled material is folded or folded material is rolled, owing to what the customers requirements are, can also be used.
  • the preparation of sheets of distance material to get lamells can be made in different ways: sawing, slicing/shearing, waterjet, laser. Many lamells can be made simultaneously by using many cutting devices in one sheet, or by letting one cutting device work in many sheets, laying on top of each other, at the same time.
  • An automatic feeding of the lamells can be made in different ways:
  • a more simple type of packaging material can be made just by laminating one side of the distance material. This can be achieved by leaving out one of the paths of material that exists on for example figure 1.
  • Printing which leads to it that the customers logotype is to be found on the finished laminate, can be made:
  • the edges of the finished laminate can be sealed with a tape, as in figure 8:
  • Qualities of the finished laminate, with between themselves different distances among the lamells, can be made by using various spreading rolls (se figure 1). The distances between the notches for the lamells can be made different on different rolls. If a belt is used (as in figure 3) different belts can be made with different distances between the notches.
  • the distance material doesn't necessarily have to be made of homogeneous material .
  • the lamells included in the packaging material don't need to be exactly of the same kind. For example different widths can be used. Lamells made from different materials can also be used in the same laminate.

Abstract

Nouveau procédé de production d'un matériau d'emballage stratifié. Selon ce procédé les feuilles réalisées en matière servant d'espacement et incorporées dans le stratifié au moment de la fabrication sont déposées transversalement par rapport au sens de déplacement du matériau dans la machine. On obtient par conséquent un parcours continu du matériau juste après la machine à stratifier, qui est incluse dans le processus de production.
