Definitions

  • the invention relates to a quickly replaceable membrane for vacuum stretching and / or drying machines for the leather industry.
  • the conventional membrane uses a separate two-part metal bracket with an integrated bracket base, which is mechanically attached to the edge of the membrane on both sides using a large number of screws and nuts.
  • the endeavor to overcome these disadvantages by means of a two-part plastic holder, which is attached to the membrane in a disposable system has also proven to be very time-consuming. The high expenditure of time and therefore of costs has only shifted from the machine user to the membrane manufacturer. In addition, the plastic parts showed material fatigue after long use, which had a negative effect on the life of the membrane.
  • the invention has for its object to construct a membrane that significantly reduces the time, labor and cost both for the user of the machine and for the membrane manufacturer.
  • This object is achieved in that instead of the holder - be it the second separate metal holder or the two-part plastic holder firmly connected to the membrane - the assembly of which is equally time-consuming and costly, an elastic connecting part is attached to the membrane, which is the carrier of one Plate with guides for the separate bracket base. This part is attached to the membrane manufacturer by simply sticking to the membrane; possibly with increased liability insurance according to claim 2.
  • the machine user merely pushes the separate mounting foot into the guides. This process takes only a few minutes and the machine is ready for use again in no time.
  • FIG. 1 the floor plan with the membrane 1, on which the elastic connecting part 2 with plate 3 is attached, preferably glued, with two guides 3a.
  • FIG. 2 - shows, in the side view, in addition to the membrane 1, the elastic connecting part 2 with a firmly connected plate 3 with two guides 3a, the membrane holder foot 4 which is inserted into the guides 3a before the membrane is used.
  • the plate 6 with the connecting element 5 can optionally support the connection between the membrane 1 and the elastic connecting part 2.
  • the supporting connecting element can preferably be rivets, screws or bolts.
  • FIG. 3 - shows the classification of the individual elements in the page image.
  • FIG. 4 - the side image of the one-piece bracket is designed as a spring bow 7, which is firmly attached to the membrane 1 by its own pretension and carries the guide 3a for the holder foot 4.

Abstract

L'invention concerne le remplacement rapide de membranes de machines d'étirage sous vide et/ou de séchage pour l'industrie du cuir, ce qui entraîne de considérables économies de temps, de travail et d'argent pour l'utilisateur comme pour le fabricant des membranes. Les fixations classiques, qui sont composées au moins de deux parties et que les utilisateurs de machines ou les fabricants de membranes devaient monter avec peine, sont remplacées par un élément de liaison (2) élastique. Cet élément de liaison (2) est collé, rapidement et facilement, sur toute sa surface sur la membrane (1) et prévulcanisé chez le fabricant de la membrane. Cet élément de liaison (2) constitue le support d'une plaque (3) dotée de guides (3a) destinés au pied de fixation (4) qui communique la force transmise par la machine. Pour une adhésion plus sûre, l'élément de liaison (2) et la membrane (1) peuvent être fixés à une contre-plaque (6). La fixation composée d'une seule pièce peut également être conçue sous forme d'étrier élastique qui, par sa prétension, pince l'élément de liaison (2) élastique et la partie supérieure de la membrane et porte, du côté de l'élément de liaison, les guides (3a) destinés au pied de fixation (4) séparé.
