  • the examples also include two PP coatings, namely a copolymer with polypropylene and low polyethylene and a polypropylene homopolymer.
  • the bursting pressure increased by at least 5 bar.
  • Coiled can coats also guarantee a higher bursting pressure compared to equally thick single-layered can coats.
  • material for the adhesive bond is applied to the first contact surface for the overlapping region which adjoins the decorative surface.
  • the high-quality pressure and at least one component for the adhesive bond can be provided with a compact device.
  • the printed strip material in the printing machine is divided continuously along its longitudinal direction into at least two subbands, which each have only the decorating surface for a can jacket in the transverse direction, the separation is efficient and the subbands can be used independently of each other for the can production.
  • At least one component for the adhesive bond is applied to the strip material with the flat material areas for the can coats prior to the separation of flat material areas.
  • the components for sealing or plastic compounds can be applied to the strip material.
  • a pressure-sensitive adhesive is applied to the strip material, which merely forms an adhesive bond when the can shells are closed between the contact surfaces of the overlapping area without a hardening mechanism by pressing.
  • the strip material is a layer of a multilayer composite material which comprises at least the printed strip material, a pressure-sensitive adhesive layer well bonded to the inside of the strip material facing away from the printed side of the strip material, and a carrier strip preferably provided with a silicone layer which forms the protective layer for forms the pressure-sensitive adhesive and due to a reduced adhesion to the pressure-sensitive adhesive layer can be easily removed from this.
  • the multilayer material composite can be advantageously built up by coating a carrier tape with a release coating and, on this release coating, with pressure-sensitive adhesive.
  • an adhesive bond must be formed between the contact surfaces of the overlap region in the case sleeves made of flat material regions. At least in the area of this adhesive bond, a corresponding area of the carrier tape must be removed from the layer with the pressure-sensitive adhesive.
  • portions of the carrier tape are used directly for the inner layer, which are available after such detachment of the flat material areas for such use. This reduces the total material consumption. Also, the weak adhesion between the release coating of the carrier tape and the pressure-sensitive adhesive layer on the flat material regions, together with the dimensional stability, is sufficiently large to keep the inner layer on the flat material region. If portions of the carrier tape are used as the inner layer, then a carrier tape can be used, which is provided on the side remote from the release coating side with a suitable for the respective can filling inner coating. Optionally, the portions of the carrier tape can be used so that the release coating is directed inwards, thereby forming an inner coating. Accordingly, the side facing away from the release coating side of the carrier tape is preferably selected so that it adheres well to the pressure-sensitive adhesive layer.
  • the can jacket is flattened at the two film ends of the metal foil or the portion of the metal strip, so that neither on the outside of the can jacket still on the inside of a step appears.
  • the middle area of the film leads from the outside to the inside between the two ends of the film and the two ends of the film stand with their end faces against the essentially radially running middle area of the film.
  • the can jacket is thus substantially the same thickness along the entire circumference, which is advantageous for the attachment of end elements. If there is only one continuous film layer at both ends of the film, this area should be regarded as a weak point. If necessary, this weak point can be avoided or reduced in that the adhesive bond between the end faces of the film ends is formed to the substantially radially extending middle film region.
  • a sensor device 24 can detect longitudinal register marks and control the separating steps so that the separated can coats each comprise a complete decorative surface 17.
  • the adhesive bond in the overlapping area is achieved with a connecting device 25, which preferably provides a required temperature and a required contact pressure and if appropriate also supplies at least one material component for the adhesive bond.
  • a tubular inner coating is attached to the inside of the resulting pipe.
  • an extrusion device 26 can be used which comprises an extrusion die, an extrusion die, at least one line leading into the extrusion die and at least one extruder, the extruder feeding at least one line with the material to be extruded.
  • FIG. 10 shows a known double-folded joint 28 between the can jacket 19 and bottom of the can 30.
  • Fig. 1 1 shows a known double-fold connection between the can jacket 19 and can lid 31. Achieving the tightness of the double Falztagenen is difficult for thin can coats 19.
  • FIG. 12 shows a known adhesive bond between the can jacket 19 and the can lid 31, wherein plastic coatings 32 of the can jacket 19 and the can lid 31 are connected to one another under the effect of heat in such a way that an adhesive bond is created.
  • the illustrated adhesive bond is not suitable for all cans, because no high bursting pressures can be achieved.
  • FIG. 17 shows an embodiment in which the can jacket 19 comprises an inner layer 40 which is closed in the circumferential direction and a flat material region 41 with a pressure-sensitive adhesive layer 42.
  • the flat material region 41 extends a little more than twice around the circumference of the shell, and correspondingly the overlapping overlapping region 20 extends a little more than once around the circumference of the shell.
  • the can coats 19 are provided outside along their entire circumference with a decorative surface 17 and have in the overlapping region 20 a subsequent to the decorative surface 17 first contact surface 18 and facing away from the decorative surface 17, or inwardly directed, second contact surface 18 'on.
  • Fig. 20 shows a section of the first processing station 45, or the turntable 45.
  • winding mandrels 54 are arranged rotatably about their own axis, being rotated during manufacture of the can coats with the turntable 45 about its axis and at the same time about its axis .
  • suction regions 55 are formed, which extend over at least part of the mandrel circumference and over the entire mandrel height or over the width of the multilayer composite material supplied by the roller 44 and are connected to a suction device such that the suction with each winding mandrel 54 individually targeted and can be turned off.

Abstract

L'invention porte sur la fabrication d'un corps de boîte (27) comprenant une paroi latérale de boîte (19) qui s'étend dans la direction circonférentielle autour d'un axe de la boîte, et qui est fermée dans la direction circonférentielle, au moyen d'un assemblage collé entre les surfaces de contact (18, 18') d'une région de recouvrement (20). Pour cela, une matière en bande (1) présentant des régions de matière plate pour la paroi latérale (19) de la boîte, est entraînée dans sa direction longitudinale par un dispositif d'impression (2) et est imprimée en continu avec des surfaces décoratives (17), des premières surfaces de contact (18) étant préparées à côté de chacune des surfaces décoratives (17). Les régions de matière plate destinées aux parois latérales de boîtes (19), qui portent chacune une surface décorative (17) et la première surface de contact adjacente (18) sont séparées de la bande de matière plate imprimée (1) et transformées en parois latérales de boîtes (19).
