Definitions

  • the invention relates to a process for the production of a coated fibrous web, in particular of paper or board, comprising the following steps: web formation from a pulp mixture with a headbox and a wire section; Drainage in a press section; Pre-drying to dry the formed fibrous web at least to a residual moisture content; Coating at least one side of the fibrous web; Post-drying and reeling of the fibrous web.
  • doctor blade coating devices the doctoring element connected downstream of a coating nozzle can be a blade or a blade or a roller blade
  • the application medium is applied with a coating unit on the surface of an applicator roll and forms a film here.
  • This application roller forms a nip with the fibrous web to be coated, in which this film is transferred to the coating side of the web.
  • the application medium only needs to be applied in the amount that is to remain on the fibrous web. This saves application medium, energy for the customer Return of excess medium and also said squeegee devices for dosing the application layer.
  • the fibrous web is spared, because the order of the medium takes place without contact.
  • the application medium is used either in a spray process, for example, with a free-jet nozzle commissioned work, for example, in the US 5,603,767 (U5210), or curtain curtain coating with a curtain coater.
  • the latter coater including method is for example in the WO 98/48112 (PU8022).
  • the coating weight range is relatively narrow.
  • a curtain coating unit is capable of ensuring perfect coverage on the coating side of the web when a closed curtain is functioning.
  • the application medium used i. the coating color is distributed very evenly, but the smoothness achieved is often insufficient for certain purposes due to the lack of leveling element (doctor element).
  • the object of the invention is therefore to provide an on-line method and a machine for producing a coated fibrous web, in particular for a special paper, which or which enables a high quality of the application layer and yet has a high productivity.
  • the object of the invention is achieved by a method according to the characterizing part of claim 1.
  • the method is carried out by providing at least one side of the web of the fibrous web at least three times with application layers, wherein at least the last two application layers are applied in a direct manner with a one-to-one coater, and this process is processed online without intermediate drying, i. wet in wet, is performed.
  • the inventors have recognized that if the last two application layers are applied with a one-to-one coater, in particular the costs for an otherwise quite high-quality and expensive functional layer (required with special papers) can be reduced.
  • a pigment-containing medium (pigment coating) is applied with a conventional doctor blade coater as the first application layer, ie as precoat or base coat, because this way the web is leveled and the pores of the fibrous web are sealed.
  • a conventional doctor blade coater as the first application layer, ie as precoat or base coat.
  • the functional layer following the base layer applied with the squeegee device can thereby be reduced in its layer thickness, as a result of which costs are also saved.
  • a function bar or a functional layer can be for example a thermo-layer, an NCR-layer or even a silicone layer.
  • the layer may also be intended to provide grease or water resistance.
  • the last layer or the coating forming the cover layer is transparent and is intended to serve as a protective layer against environmental influences, fats, oils, water abrasion, etc.
  • the method according to the invention is suitable for one-sided but also for two-sided applications.
  • one side is first pre-painted and immediately painted over. Thereafter, the coating of the second web side takes place in the same manner.
  • the object of the invention is also achieved with a machine for producing the coated fibrous web.
  • a machine for producing the coated fibrous web for the application of at least three coating layers on at least one web side of the fibrous web for the at least two last application layers at least a 1: 1 applicator, that is a curtain applicator and / or a Sprüh Publishedswerk provided without arranging an intermediate drying device.
  • a 1: 1 coating unit With such a 1: 1 coating unit, a complete and particularly uniform coverage of the fibrous web surface can be achieved.
  • This curtain application plant has at least one application head arranged above the fibrous web and spaced therefrom.
  • the applicator head includes at least one medium distribution chamber and at least one application or dispensing nozzle communicating with the distribution chamber via a supply nip for a coating medium curtain to be dispensed to the fibrous web underneath.
  • a first variant may consist in that a single application head is arranged with parallel distribution chambers. From each distribution chamber for the application medium used branches off a supply gap. The feed gaps unite at the exit of the applicator head in a common dispensing nozzle for dispensing a double layer application medium curtain. This design is referred to by the applicant company as a "twin" design.
  • a further variant may consist in that the curtain applicator has two applicator heads arranged one after the other running parallel to one another in the running direction of the fibrous web, each containing one feed chamber, one feed gap and one dispensing nozzle each for dispensing a single-layer application medium curtain.
  • the two curtains lay down only on the fibrous web as a double layer.
  • This design is referred to by the applicant company as a "tandem design”.
  • a further variant may consist in that the curtain applicator has two mutually offset, parallel in the direction of the fibrous web, successively arranged applicator heads each having a feed chamber, a respective supply gap and a respective dispensing nozzle for dispensing a single-layer application medium curtain. Below this single-layer curtains, an inclined collecting plate is arranged, on which the said curtains deposit one above the other and lead to a double layer, which then forms a double-layer application medium curtain, which also deposits as in the first variant as a double layer on the surface of the fibrous web ,
  • a further variant may also consist in that the curtain applicator has indeed a single application head but with mutually offset in height, parallel distribution chambers.
  • the feed gaps branching therefrom run upwards in the direction of an inclined run-off plane or sliding surface, on which the respective emerging application medium unites to form a double layer, thereby forming a double-layer application medium curtain.
  • this double-layered curtain likewise again lays down as a double layer, that is to say the previously described functional layer and covering layer on the fibrous web.
  • a smoothing device is arranged before and / or after the first applicator unit and / or before the reeling at the end of the machine.
  • a triple coating of the same web page is first made directly.
  • this consists of an application unit 12.1 assigned to the coating side 7a with a blade or roller blade as a leveling or metering element 12.2 and of a backing roller 12.3 supporting the fibrous web 7 on the opposite side 7b during coating.
  • glue or starch for penetrating and strengthening the fibrous web 7 or even a pigment-containing coating color is used for the purpose of achieving good printability of the web page 7a.
  • At least one contour line completely covering the web is subsequently applied with at least one so-called 1: 1 applicator 15.
  • a curtain coater 16 is provided for applying the following two contour lines or layers, which is shown in FIG. 1 should be indicated with two curtain applicator heads 16.1.
  • the two applicator heads 16.1 are arranged above and at a distance from the fibrous web 7 and could therefore be part of a single applicator 16 or even two successively arranged applicators 16 represent.
  • a functional layer 17 and as a conclusion a protective layer 18 against environmental influences on the web 7 are applied. Due to the leveling done with the applicator 12, the subsequent functional layer 17 can be reduced in their layer thickness, thereby saving costs.
  • the function bar or the functional layer 17 may, for example, a Thermo layer, an NCR layer, a silicone layer, etc.
  • the layer may also be intended to provide grease or water resistance.
  • the last layer or the coat forming the cover layer is transparent and is intended to serve as a protective layer 18 against environmental influences, fats, oils, water abrasion, etc.
  • FIGS. 2 to 5 all the media resulting from the right distribution chamber 6a are dotted and the ones resulting from the left chamber are dotted lines FIG. 5
  • the Functional layer 17 here in dotted line and the cover or protective layer 18, indicated in dashed line.
  • an after-smoothing 19 (not shown) with single-nip calenders or a multinip calender, for example a Janus calender known per se, can take place prior to winding up.
