Definitions
- the invention relates to a drying group with a device for the optional treatment of running webs, preferably made of paper or cardboard.
- the coating device is assigned to the drying group consisting of drying cylinders of a paper machine.
- FR-A-22 02 192 discloses a post-dryer group with a device for coating paper, a deflection roller being provided in an intermediate space between two adjacent drying cylinders, from which the web is fed to the coating device.
- the object of the invention is therefore to provide a space-saving after-dryer group, it also being possible to bypass the coating device.
- the bypass route should be as simple as possible and short.
- the space between the two adjacent drying cylinders of the after-dryer group corresponds to the at least one deflection roller for bridging the space in the event that the web is not treated by a coating device arranged in this area of the web course for painting, pigmenting or gluing, and the takes up at least one further deflection roller, at most two diameters of the drying cylinders.
- the coating device is arranged practically above this space.
- Dryers which preferably work on the basis of infrared radiation or hot air, are preferably located in front of the coating device. With existing paper machines, it is therefore practically only necessary to remove two adjacent drying cylinders and to provide the necessary guide rollers for the web in the free space that is created.
- the coating device here preferably consists of two press rolls or web guide rolls 1 and 2 which form a press nip with one another. Each of them is assigned a coating applicator unit 3 or 3 ', which are constructed essentially identically and are arranged in mirror image.
- Each application unit can consist of a doctor blade or a similarly constructed holder 5 for a bed 7 of a doctor blade 6 and a throttle plate 8 connected upstream in the direction of movement of the outer surface of the press rolls, an application space for the coating slip or general coating compound being formed between these parts, which is preferably under is above atmospheric pressure, and to which the coating slip can be fed from a coating chamber 9.
- the coating device are Downstream heating devices 51, 52 and 53, which can work on infrared basis or with hot air.
- Further deflecting rollers 21-23 then feed the coated and pre-dried web to the remaining drying cylinders 49, 50 and the following, so that the web is completely dried.
- the coating device can only be used at a time when the web already has a considerable dry content, which is at least 75, preferably at least 80%.
- the coating device is suitable for impregnating the web with glue or for coating it with pigment.
- a moisture meter 40 is installed between the idlers 16 and 18.
- the coating device with the rollers 1 and 2 is preferably arranged on a higher machine floor or on a machine foundation arranged one floor higher than the drying cylinder group.
- the distance between the drying cylinders arranged at the space leading to the coating device is at most two diameters in length - based on the row arrangement of the drying cylinders.
- the great advantage of the arrangement is that in the event of a web break - if preferably on the coating machine - the web can easily be driven into the basement before it is re-threaded.
