Definitions

  • the invention relates to a device of the preamble of claim 1 corresponding type.
  • the fluid treatment or sample agent for example a coloring liquid moves in one thin layer over the surface of the drain plate.
  • This thin layer has a relatively large surface area which is an evaporation with corresponding strong cooling the low liquid mass takes place.
  • Such Cooling of the treatment or sampling agent not desirable in many cases.
  • the treatment or patterning agent previously increased to just one Temperature that is optimal for the exposure brought. This temperature drops on the way over the drain plate in a way that is difficult to understand.
  • the invention is based, such Counteract temperature drop.
  • the temperature drop can reduced or possibly even a temperature increase of the treatment or sample agent immediately be achieved before the transition to the web, depending after like the control provided according to claim 2 is made. In this way, by means of the invention even the process can still be influenced.
  • the device one with the bottom of the drain plate thermally connected Surface heating element include, for example electric heating jacket in the manner of a heating pad (Claim 3).
  • the drain plate is double-walled executed and the space between the walls of flows through a heat transfer medium, the flow, in order to maximize the width of the web uniform temperature influence of the treatment or Ensure sampling means in at least two parallel flow paths take place in countercurrent should (claim 5).
  • the drain plate of two each other parallel opposing walls are formed, which are kept at a distance by spacers and with each other are connected.
  • spacer elements can according to claim 7 individual pegs consist, in particular, of threaded weld bolts according to claim 8, when the upper of the surfaces is formed consists of sheet metal.
  • An important embodiment of the invention is Cord according to claim 9, by means of which in a simple manner between the walls depending on the pattern of the laying the cord flow paths formed and this after can be sealed outside.

Down the flat channel 10 through a sealing arrangement 20 completed by both sides the web 1 is applied and the treatment liquid runs out prevented from the flat channel 10 down.
  • a squeeze mechanism 30 is located above the flat channel 10 with two nip rollers 32, 33 working against each other arranged which soaked in the flat channel 10 Squeeze web 1 to a predeterminable moisture content, so that a certain amount of treatment liquid remains on the web 1 in an even distribution.
  • the web 1 runs from above via one below the spreading roller arranged in the application device 100 2, is deflected there by approximately 90 ° and reaches approximately horizontally a deflecting roller 3. Of which on the right in Fig. 1 The web 1 runs vertically upwards and above the flat channel 10 via another spreader roller 4, then into the nip 31 of the nip rolls 32 and 33 to enter.
  • the flat channel 10 consists of two with little Distance between opposing rectangular sheets, which form the flat sides 5.5 of the channel 10.
  • the longer ones Sides of the rectangular sheets are in the width direction of the Lane 1 located. Between the upright shorter ones
  • the sides of each side are rectangular in cross-section Distance profile 6 arranged, the supplement profiles on the outside Face 7.7.
  • the whole is through one Row of screws 8 connected and in a suitable manner sealed so that one in a horizontal cross section closed channel 10 results.
  • Above and below the flat channel 10 opens out.
  • a support structure is provided, of which only two opposite each other at the same height I-beam 11, 12 are reproduced.
  • the I-beams 11, 12 each have a transverse web 11 ', 12' by far opposite. In the space are at the Crosspieces 11 ', 12' mounting pieces 13,14,15 mounted that the lower end of the flat channel 10 and the sealing arrangement 20 hold on. If necessary, the flat Channel 10 still in another place in not reproduced Be supported.
  • the squeeze rollers 32, 33 are above the discharge surfaces 16 and arc tube 18 in the area of the floor plan the flat channel 10 is provided with its support arrangement.
  • the treatment liquid squeezed in the roll gap 31 flows down or down along the web 1 drips off.
  • To collect this treatment fluid are guide surfaces 34, 35 on both sides of the web 1 provided below and to the side of the nip rollers 32.33 collecting treatment liquid and lead to the drain surfaces 16, where they again in the flat channel 10 is returned.

  • the walls 21,23 also consist of plastic, but is there no simple shaping by angling is possible.
  • FIG. 2 Another in Fig. 2 is contemplated for the invention upcoming drain plate 22 'reproduced as Doctor blade on a roller 25 rotating in the direction of the arrow whose side is falling as it circulates.
  • the roller 25 dips with its lower part into a basin 26 located treatment liquid 27, which is in circulation the roller 25 taken from this at its beginning and stripped from the drain plate 22 'from the circumference of the roller 25 becomes.
  • the treatment liquid 27 moves in a thin layer over the surface of the drain plate 22 'and falls in from its horizontal lower edge a uniform veil 28 on the one below in the direction of the arrow passed web 1.
  • FIG 3 shows a drain plate 22 ", on the upper area of several feeders 36,37 a coloring foam 38 is delivered, which is about the drain plate 22 ′′ inclined towards the web 1 moved down and up from their horizontal bottom edge the web 1 passes over.
  • the drain plate 22 " is a nozzle tube 39 provided from which tempered air against the bottom the drain plate 22 "can be directed so that it is heated or, if desired, also cooled.
  • the area IV of the drain plates 22 is off Fig. 1 shown enlarged.
  • Below the upper wall 21 is one arranged lower wall 23, which is parallel to the upper Wall 21 runs and at the edges one at the Flat sides 5.5 adjacent bend 43 and a tight outside the bend 42 extending vertically upwards has pointing bend 44 which stabilize the wall 23.
  • the walls 21, 23 are by means of threaded weld bolts 45 connected together at the bottom of the top Wall 21 are welded, reach through the lower wall 23 and provided with cap nuts 46 screwed onto the outside are.
  • the Leg 53,54 of the "U” run across the web and are connected by the web 55.
  • the string 51 runs outside on the edges of the legs 53, 54 and along the web 55. It is outside around the outer rows 47,49 of the thread welding bolt 45 is guided around and runs between the adjacent thread welding bolts 45 ' inwards on both sides of the middle row 48.
  • the cord 51 is underneath between the walls 21, 23 the effect of the nuts 46 to be tightened and thereby seals the entire flow path 52 laterally.
  • the heat transfer medium flows thus in the flow paths given by the legs 53, 54 in countercurrent, so that the Temperature is achieved.
