Definitions

  • the invention relates to a for the production and / or treatment of a material web, in particular paper or board web, applied to the glue web or a pasty or liquid coating on the web and the web is guided to press the glue or the coating through a press nip, wherein the glue or the coating is applied to the material web at most in the width of the uncut material web.
  • the publication EP 0 079 759 A1 discloses a method of providing a surface imprint in a sheet material coating wherein a flowable coating of a curable composition or a curable material is applied to one side of a sheet of the sheet material. It is provided that the coating applied to the sheet material coating does not extend beyond the edge of each side of the sheet material.
  • the invention has for its object to provide an improved method of the type mentioned, in which the aforementioned disadvantages are eliminated. It should be ensured in particular that the press fabric is not contaminated by applied in the press section glue and / or no chemicals from the sizing (starch, resins, pigments, binders, ...) get into the white water cycle. At the same time, it should be ensured that in the practical application, finally, the material web wound on the roller is provided with glue or a coating in its entire width.
  • This object is achieved in that the material web is supported during the application of the glue or the coating of a press fabric and that for the first time after the press nip edge trimming of the material web is performed.
  • the glue or the coating can be applied in particular narrower than web width on the material web. The glue or the coating is thus carried out so that contamination of the press fabric is prevented.
  • web width is to be understood here in particular as the width of the material web before the first edge trim or the width of the material web at the respective point in the process, including entrained edge ribbons.
  • a second edge trimming of the material web is carried out after the press nip.
  • an edge trimming of the material web is carried out for the first time before transferring the material web into the next part or section of the production machine.
  • a marginal trimming of the paper web can be carried out for the first time before transferring the material web into the next press nip, into an offset press, into a dryer group and / or the like.
  • edge trimming of the material web is carried out for the first time after the transfer of the material web into the next part or section of the production machine.
  • a marginal trimming of the paper web can be carried out for the first time after the transfer of the material web into the next press nip, into an offset press, into a dryer group and / or the like.
  • At least the contaminated edges of the respective press fabric comprising at least one circulating belt are cleaned so that at most a minimal amount and preferably no chemicals originating from the sizing or coating enter the white water circuit.
  • the contaminated edges of the relevant, at least one rotating belt comprehensive press fabric can be at least pre-cleaned, including in particular a special additional cleaning can be provided. This ensures that no significant amounts of interfering chemicals pass through conventional conditioning of the covering (press felt) into other water circuits.
  • the severed edge strips are removed before transferring the material web into the next part or section of the production machine.
  • the severed edge bands can thus be removed, for example, before transferring the material web into the next press nip, into an offset press, into a drying group and / or the like.
  • the separated Randbändel can be removed in particular laterally or vertically from the manufacturing machine.
  • the separated Randbändel can be removed for example by means of a Bändelabsaugung from the manufacturing machine.
  • the separated Randbändel be removed only after the transfer of the material web in the next part or section of the manufacturing machine.
  • the severed edge bands are thus removed, for example, only after the transfer of the material web in the next press nip, in an offset press, in a drying group and / or the like.
  • the removal of the separated Randbändel from the manufacturing machine can in particular be done again by means of a Bändelabsaugung.
  • the separated Randbändel are preferably removed laterally from the manufacturing machine in the present case.
  • the fabric edges located in the region of the material web edges are conditioned separately.
  • the clothing edges can therefore be conditioned in particular separately from the rest of the clothing.
  • edge zones of the clothing are expediently dimensioned such that the material web edges lie within the edge zones of the clothing. It can be advantageous in certain cases, if from the edge zones the clothing resulting water is treated separately from the rest of the resulting water. If necessary, therefore, a special treatment of the water arising from the edge zones is conceivable.
  • the separated glued or coated material web edges are treated and recycled in particular by intermediate drying, neutralization and / or the like so that the chemistry within the wet end is not disturbed.
  • the sealed edges are resistant to chemicals (starch, %) of the coating and easier to clean.
  • the press fabric is hydrophobicized in the region of the first and / or second edge band or impregnated with water-repellent agents.
  • the method according to the invention achieves a simple process control close to the process control usual today in the press section.
  • the paper web ultimately obtained is glued to the web. No further trimming of the edge rolls is required.
  • the basic idea of the invention lies i.a. It is to make the glue application or the coating of the material webs so that a contamination of the press fabric is prevented.
  • the sole figure of the drawing shows a purely schematic representation of a device 10 for applying glue or a pasty or liquid coating on a moved in the direction L web 12, which may be in particular a paper or board web.
  • the device 10 comprises an applicator roll 14, which forms a press nip with a mating surface, through which the material web 12 is passed for pressing in the glue or for applying the coating.
  • the glue supply or the coating takes place via an applicator 16 assigned to the application roller 14. This is dimensioned and / or adjustable in such a way that Glue or the coating 18 web width or narrower than web width is applied to the web 12.
  • the material web provided with a corresponding glue application or coating is designated by "12", while the separated or to be separated edge ribbons are designated by "20".
  • the applicator 16 is thus preferably dimensioned or adjusted so that only the material web 12 and not also the separated or separated edge band 20 are exposed to glue.
