- the fluid treatment or patterning agent for example a coloring liquid, moves in a thin layer over the surface of the drain plate.
- This thin layer has a relatively large surface area, on which evaporation takes place with a correspondingly strong cooling of the low liquid mass.
- Such cooling of the treatment or patterning agent is not desirable in many cases.
- the treatment or patterning agent is usually brought to an elevated temperature which is optimal for the action. On the way over the drain plate, this temperature drops in a way that is difficult to understand.
- the object of the invention is to counteract such a drop in temperature.
- the temperature drop can be reduced or possibly even a temperature increase. Hung of the treatment or sampling agent can be achieved immediately before the transition to the web, depending on how the control provided for in claim 2 is carried out. In this way, even the process can still be influenced by means of the invention.
- the device can comprise a surface heating element connected to the underside of the drain plate in a heat-conducting manner, for example an electrical heating jacket in the manner of a heating pad (claim 3).
- the drain plate is double-walled and the space between the walls is flowed through by a heat transfer medium, the flow in order to ensure the most uniform possible temperature influence of the treatment or patterning agent over the width of the web at least two mutually parallel flow paths should take place in countercurrent (claim 5).
- the drainage plate can be formed by two mutually parallel walls which are kept at a distance by spacing elements and are connected to one another.
- spacer elements can consist of individual pins according to claim 7, in particular of threaded weld studs according to claim 8, if the upper of the surfaces consists of sheet metal.
- An important embodiment of the invention is the cord according to claim 9, with the aid of which flow paths can be formed between the walls in a simple manner depending on the pattern of laying the cord and these can be sealed off from the outside.

- holding pieces 13, 14, 15 are mounted, which hold the lower end of the flat channel 10 and the seal arrangement 20. If necessary, the flat channel 10 can be supported at another point in a manner that is not reproduced.
- the plates or sheets forming the flat sides 5, 5 of the flat channel 10 are angled outwards and form inwardly inclined drainage surfaces 16, via which the treatment liquid in a film or a layer obliquely downwards into the upper end of the flat Channel 10 runs in.
- Outside the drainage surfaces 16 there are horizontal supply pipes 17 for treatment liquid, which extend parallel to the flat sides 5, 5, which are supplied with them in a suitable manner and are connected to a plurality of arc tubes 18 which follow one another in the width direction and which are connected are bent like a walking stick and over the upper edge the drain surfaces 16 are sufficient.
- the treatment liquid which is brought to the drainage surfaces 16 at a large number of points which are fairly close to one another through the curved tubes 18 flows down over the drainage surfaces 16 and is evened out in the process, so that the flat channel 10 is kept filled without significant level differences in the width direction of the web 1 can be.
- the squeeze rollers 32, 33 are provided above the discharge surfaces 16 and arc tubes 18 in the area of the plan of the flat channel 10 with its support arrangement.
- the treatment liquid squeezed in the roll gap 31 flows downward or drips off along the web 1.
- guide surfaces 34, 35 are provided on both sides of the web 1, which collect treatment liquid accumulating below and laterally from the squeeze rollers 32, 33 and guide them to the discharge surfaces 16, where they are returned to the flat channel 10 .
- the drainage surface 16 is formed on the upper side of a drainage plate designated as a whole by 22, one of which is arranged in mirror image of the web 1.
- the drain plate 22 is double-walled and consists of an upper, flat wall 21, the upper side of which is the drain surface 16, and a further wall 23 arranged at a distance below it.
