Definitions

  • the invention relates to an application device according to the preamble of claim 1.
  • Such a device is known from DE 41 00 771 AI. It is provided here that the pressure hose serves to compensate for the bend or to adjust the bend for the support member with the curved guide surface. However, due to hydrodynamic forces occurring differently over the length of the support member during the coating process, the same is curved, so that a compensation of this curvature is also necessary.
  • the radius of curvature of the guide surface of the support member can no longer be so small.
  • the strip or bar-shaped support member 1 is arranged parallel to a counter roll C. This is supported by a bar 3 running parallel to the support member 1, initially via a pressure hose 4 arranged at the end of a web or strip-like extension 2 of the support member 1.
  • the support member 1 has an application gap 9 formed with reference to the counter roller C. curved guide surface for a coating tape or hose 7. The latter is guided over a drive roller 6.
  • the diameter of this drive roller is preferably between 400 and 900 mm and the radius of the guide surface of the support member 1 can be between 40 and 150 mm.
  • a further pressure hose 5 engages on the web-like extension 2 of the support member 1, in the transverse direction to the line of action of the first pressure hose 4. The deflection of the support member 1 in the vertical and horizontal directions can be influenced or be balanced.
  • piezotranslators instead of the pressure hoses, corresponding rows of piezotranslators or pressure pistons guided in pressure cylinders can also be provided.
  • a manufacturer of these piezotranslators is PI Physik Instrumente GmbH, Siemensstrasse, 7517 Waldbronn, Federal Republic of Germany. - 3 -
  • the coating takes place by means of the band or hose 7, which is guided through a trough 12 containing the coating material (liquid).
  • FIG. 2 is between the additional tube 5 'and the strip-like extension 2' of the supporting member 1 l disposed an intermediate plate 8.
  • the contact surfaces of the extension 2 'and the intermediate plate 8 are made very smooth, there is only a slight hindrance to the deformation of the support member 1' to be achieved due to the pressure hose 5 'by a u. U.
  • Material of the pressure hose 5 ' provided with a relatively large coefficient of friction.
  • This intermediate piece the area moment of inertia of the strip-like extension 2 or 2 1 can also be reduced in order to keep the bending forces which the pressure hose 4 or 4 1 has to apply as small as possible.
  • This intermediate plate 8 is held on its two end edges, shown in the figure, by projections on the support beam 3 '.

Abstract

L'invention concerne un dispositif pour l'enduction de feuilles continues en déplacement, notamment en papier ou en carton, comprenant une bande ou un tuyau flexible (7) qui est guidé autour de la surface de guidage incurvée d'un organe-support (1) en forme de poutrelle ou de barre, et d'un rouleau d'entraînement (6), un cylindre antagoniste (C) guidant ladite feuille continue. Un espace (9) est ménagé entre le cylindre antagoniste (C) et le tuyau flexible (7) pour l'application de la masse d'enduction sur la feuille ou le cylindre, une poutrelle-support (3) s'étendant parallèlement au cylindre et au rouleau d'entraînement (6), pour supporter l'organe-support (1), cependant qu'il est prévu, entre ce dernier et la poutrelle-support, un tube en caoutchouc à vide (4) destiné à transmettre les forces d'appui. Conformément à l'invention, l'organe-support (1) présente un prolongement en forme de traverse ou de bande dans sa zone située à distance de la surface de guidage incurvée sur l'espace (9), prolongement sur lequel un autre tube en caoutchouc à vide (5, 5') disposé entre une surface d'appui correspondante de la poutrelle-support (3) et le prolongement de l'organe-support (1) vient s'engager sensiblement perpendiculairement à la direction d'engagement du premier tube en caoutchouc à vide (4, 4'), ledit premier tube étant disposé sensiblement à l'extrémité libre du prolongement (2, 2') de l'organe-support (1, 1').
