Definitions

  • the present invention relates to installations used for coating fabrics or other flexible supports with a layer of synthetic material (polyvinyl chloride, resin, elastomer, etc.) with a view to producing a complex having a very high mechanical resistance combined with perfect impermeability.
  • synthetic material polyvinyl chloride, resin, elastomer, etc.
  • French patent no. 73 35081/2 245 165 FERRARI shows an installation equipped with a coating station comprising, first of all, means suitable for ensuring the longitudinal and transverse tension of the support, these means advantageously being constituted by the clamps or pins of a mobile train longitudinally. This support was thus kept under tension until the final calendering operation.
  • the coating station also included at least one die oriented transversely to the direction of continuous advance of the support. This die had two parallel doctor blades offset with respect to each other in the direction of advance of the support, thereby defining a cavity or chamber supplied with coating material, this supply taking place continuously and under controlled pressure.
  • the invention mainly consists in making the installation comprise two channels which are arranged in superposition on either side of the support to be coated so as to produce on the latter a double-sided coating.
  • Fig. 1 is a perspective view schematically illustrating the arrangement of the double-sided coating station of an installation according to the invention.
  • Fig. 2 is a partial longitudinal section showing on a larger scale the two opposite dies of the installation according to FIG. 1.
  • reference 1 designates the support to be coated, assumed to be constituted by a fabric.
  • This fabric 1 is animated by a continuous advance movement, oriented from left to right in FIG. 1.
  • the fabric 1 is successively engaged between the superimposed drums of two calenders 2 and 3, arranged to continuously exert on said fabric a controlled tension effect, oriented longitudinally; associated with this longitudinal tension is a transverse tension, operated as in Patent N ° 73 35081/2 245 165 FERRARI, using an oar 4 for holding it wide, the clips or pins are applied to the longitudinal edges of the fabric 1 upstream of the grille 2.
  • the coating station also comprises two superimposed dies 5 and 6, the arrangement of which appears on a larger scale in FIG. 2.
  • Each die 5 or 6 is formed by a frame 7 permanently fixed to the structure of the station.
  • Each frame 7 is associated with an upstream doctor blade 8 whose edge turned towards the fabric 1 has a rounded profile, and a downstream doctor blade 9 whose free edge applied against the fabric 1 has a pointed profile.
  • the position of the doctor blades 8 and 9 in the vertical direction can be adjusted precisely, for example using screws such as those shown at 10, so that the application of the free edge of said doctor blades against the two opposite faces of the fabric 1 is capable of being fixed exactly exactly, as a function of various parameters, in particular the thickness of the coating layer to be deposited on each side, it being observed that this adjustment is capable of being carried out in such a way fully autonomous, for each of the two doctor blades of each die.
  • the doctor blades 8 and 9 define, with the inner face of the frame 7 and the fabric 1, a cavity 11 intended to form the coating chamber.
  • Each of the cavities or chambers 11 is connected, through a series of distributing channels 12 suitably spaced along the length of each die, to a collector 13 supplied by an independent reservoir 14, respectively 15, permanently filled with an appropriate quantity of material coating.

  1. Einrichtung zum Beschichten von horizontal abgespulten Geweben oder anderen, weichen Trägern, gattungsgemäß ausgestattet mit einer Beschichtungsstation, die einerseits Mittel (2-3 und 4) zum Sicherstellen der Längs- und Querspannung des Trägers (1) umfasst, andererseits mindestens eine, hinsichtlich der fortlaufenden Vorschubrichtung der Unterlage quer ausgerichtete Breitschlitzdüse (5,6), die zwei parallele Rakel (8,9) aufweist, von denen die eine gegenüber der anderen in Richtung des Vorschubs der Unterlage zur Bildung einer Höhlung oder Versorgungskammer verlagert ist, zur kontinuierlichen Zuführung des Beschichtungsmaterials und zur Überwachung des Druckes, dadurch gekennzeichnet, daß sie zwei Breitschlitzdüsen (5 und 6) umfasst, die übereinander angeordnet sind, zur doppelseitigen Beschichtung des Trägers (1).
  2. Einrichung nach Anspruch 1, dadurch gekennzeichnet, daß der gegen den Träger (1) gerichtete Rand der Rakel (8, 9) jeder der Breitschlitzdüsen (5, 6), für die einlaufseitige Rakel (8) als abgerundetes Profil ausgebildet ist, und als spitz zulaufendes Profil für die ablaufseitige Rakel (9).
  3. Einrichtung nach einem der Ansprüche 1 und 2, dadurch gekennzeichnet, daß die Breitschlitzdüsen (5, 6) ein festes Unterteil (7) umfassen, gegenüber dem die beiden gegeneinander gerichtenen Oberflächen fix sind, wobei die beiden Rakel (8, 9) in ihrer vertikalen Position einstellbar sind.
  4. Einrichtung nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß jede der Breitschlitzdüsen (5, 6) einen Sammler (13) umfasst, der über eine Reihe von Verteilkanälen (12) mit der Versorgungskammer (11) der Breitschlitzdüsen verbunden ist.
  5. Einrichtung nach Anspruch 4, dadurch gekennzeichnet, daß jeder Sammler (13) aus einem Vorrratsbehälter (14, 15) mit Beschichtungsmaterial versorgt wird, wobei der Vorrratsbehälter ständig aufgefüllt wird und dessen Höhen-Lage veränderbar ist, um die genaue Regulierung des Druckes des Beschichtungsmaterials in der der Versorgungskammer (11) jeder der Breitschlitzdüsen (5, 6) zu ermöglichen.
  6. Einrichtung nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß die Mittel zum Spannen gebildet sind, einerseits durch einen Spannrahmen (4), der die längsverlaufenden Ränder des Trägers (1) zurückhält, andererseits durch zwei Walzkalander (2,3), die beiderseits der beiden übereinanderliegenden Breitschlitzdüsen vorgesehen sind.
