Definitions

  • the invention relates to a water- and gas-tight zipper with the features of the preamble of claim 1.
  • Such a method is known from DE-C-41 29 191.
  • a closed spiral zipper is coated with a thermoplastic material in an extrusion process and fed to a cooling section, the zipper tapes being subjected to a tensile force laterally. Then the zipper is separated.
  • the object of the present invention is to provide an improved method for producing a water- and gas-tight zipper, in which such a zipper can be inexpensively manufactured with complete tightness using simple means.
  • a closed zipper consisting of two zipper tapes with spiral zipper halves made of plastic, is produced by the injection molding process.
  • the zipper is overmolded in sections in a gradual advance.
  • a lateral tensile force is exerted on the zipper tapes at least during the spraying process.
  • the coating material is a thermoplastic polyurethane, the coating being pre-slit in the opening direction at least at the top before the first separation of the zip fastener tapes.
  • the bottom coating essentially closes with the bottom of the
  • spirals can be elastically connected to the zip fastener tapes and each have a core that is elastically deformable in the lateral direction.
  • the cut for the pre-slitting is preferably carried out by means of a cam control or the like on at least one intended end with a modified cutting depth.
  • a further injection or extrusion process is carried out in the slot and / or at least one further parallel slot
  • the zipper is available by the meter before the spraying process, the closed overmolded zipper is cut to length in certain dimensions and a port is sprayed on in a second spraying process.
  • the port is designed as a circumferential bead and encloses a port hole, the port in the port hole having a sealing lip for a pusher heart and a sealing ring or a sealing lip can also be arranged on top of the port.
  • the bead is advantageously gutted on the inside on its underside.
  • the port has a wedge-shaped transition from the coating profile to the port, for example, so that the legs of the slide exert increased lateral pressure.
  • the end of the zipper at which the port is to be molded is to be provided with a connection-improving profile, for example a notch. Furthermore, an end stop is sprayed on at one end at the other end next to the port.
  • the zipper tapes are provided with a pre-coating or lamination before coating, the
  • Pre-coating or lamination can have adhesive values of up to over 180 N / 5 cm (DIN).
  • the zipper tapes are first roughened before further processing and / or provided with an adhesion promoter before coating.
  • Figure 1 shows a coated zipper section.
  • FIG. 3 shows a zipper section with a molded port
  • Fig. 4 shows a finished zipper section
  • F Fiigg .. 5 5 a zipper slider
  • FIG. 6 shows the port of FIG. 3 enlarged
  • Fig. 7 shows a section through port and slide.
  • Fig. 1 shows schematically a coated zipper, consisting of two zipper tapes with a closed spiral zipper, which is encapsulated with a coating composition 2, with a box-shaped profile made of the coating material at the top and the lower coating is substantially flat with the underside of the zipper tapes.
  • the zipper is a cut-to-length section of a zipper strand which is produced step by step by an injection molding process.
  • Fig. 2 the zipper is shortened to the desired length and at the front end there is a notch 4 for better connection to a port 6 to be molded (Fig. 3). At the rear end there is a projection 3 corresponding to the notch for better connection to an end stop 8 (FIG. 4). 3 shows the section 5 with which the two partial strands of the coating 2 are separated.
  • the port 6 has a port hole 7 and, like the end stop 8, is injection molded in further injection molding processes.
  • Fig. 5 shows a slide 9 with a
  • FIG. 6 the port 6 is shown enlarged.
  • a sealing lip 11 for the pusher heart 10 (FIG. 7) is arranged all around in the port hole 7.
  • a second sealing lip 12 is formed around the port hole on top of the port 6, so that, as shown in Fig. 7, a double seal between the sealing lips 11, 12 of the port and the slide 9 is made.
  • Fig. 7 also shows a core 13 which runs around the inside of the port hole and ensures an improved seal.
  • the transition 14 between the zipper and the port is slightly oversized so that the legs of the slider exert greater lateral pressure on the transition. In the transition, section 5 of the zipper is continued in a further partial section 15 up to the port hole.

Abstract

L'invention concerne une fermeture à glissière étanche à l'eau et au gaz, notamment une fermeture à spirales en matière plastique. Les spirales sont surmoulées au moyen d'un élastomère thermoplastique qui est respectivement placé, côté dessus, sur les bords jointifs des bandes de la fermeture à glissière sous la forme d'un revêtement profilé. Ces revêtements profilés, réalisés par un procédé de moulage par injection, sont en contact l'un avec l'autre de façon étanche sous l'effet d'une pression lorsque la fermeture est fermée.
