Definitions
- the subject of this invention is a process for producing a multilayer fibrous web with a white top layer, optionally one or more intermediate layers and a supine layer.
- the individual layers of the fibrous web are formed in a forming section and vergautscht together so that the white cover layer forms the bottom of the multilayer fibrous web.
- the multilayer fibrous web is dewatered in a press section.
- white-covered testliner coated or uncoated
- white top testliner white-topped kraftliner
- white-covered Krafttopliner Ker Top White
- plasterboard Paster Board Liner
- paperboard carton white lined chipboard
- liquid packaging board liquid packaging board
- folding box board primarily white-covered testliner (coated or uncoated) also known as white top testliner or white-topped kraftliner (White Top Kraftliner) or white-covered Krafttopliner (Kraft Top White), or plasterboard (Paster Board Liner), paperboard carton, white lined chipboard, liquid packaging board, or folding box board.
- the white cover layer forms the underside of the multilayer fibrous web ("upsidedown production"), because in the subsequent press section in particular the underside of the fibrous web is smoothed.
- a smooth white top layer is a prerequisite in many manufacturing processes.
- the supine and possibly also the intermediate layers consist of fibers which have a lower whiteness than the white cover layer.
- the upper sieve After covering the multilayer fibrous web, the upper sieve must be lifted off the fibrous web and the fibrous web must continue to run on the lower sieve. For this to work reliably, there is a vacuum cleaner under the lower sieve, which ensures that the fibrous web adheres to the lower sieve and does not run along with the lifting upper sieve. Often even more suction boxes are arranged in the lower sieve, through which the vergautschte fibrous web is further dehydrated. However, the suction effect of the vacuum cleaner or the bottom suction boxes also sucks dirty water from the supine position in the white top layer, which thereby loses whiteness.
- the object of the present invention is to disclose a production method for producing a multilayer fibrous web with a smooth white cover layer, in which the whiteness of the cover layer is improved over conventional methods.
- This manufacturing process is particularly well suited for the production of White Top Testliner, White Top Kraftliner, Kraft Top White Liner, Plaster Board Liner, White Lined Chipboard, Liquid Packaging Board or Folding Box Board.
- the upward vacuum dewatering after gassing preferably takes place with the aid of a suction box arranged above the fibrous web.
- This suction box is thus arranged in the upper sieve, it can also be made.
- the multilayer fibrous web passes through the subsequent press section such that the white cover layer is not brought into contact with a press felt, at least in one nip, preferably in the last nip.
- the white cover layer is thus brought into contact with an unfilled press roll or a smooth transfer belt.
- the supine position is formed in a twin-wire former.
- the supine position in Doppelsiebformer be deflected by a guide roller down, wherein the guide roller is wrapped by two wires of Doppelsiebformers. By looping the guide roller lifting or spinning the supine position of the lower wire is prevented.
- the guide roller may also be sucked.
- the multi-ply fibrous web consists of at least three layers, which are successively laped together, it is advantageous if the vacuum dewatering according to the invention takes place only directly after the last embedding.
- the white cover layer and / or the backsheet can be applied to a forming fabric with the aid of a multi-layer casserole.
- the white top layer is applied to the screen by means of a multi-layer casserole, the layer of the white top layer which ultimately forms the surface of the multi-ply fibrous web should have the largest whiteness.
- the forming section 2 is shown as a multilayer wire section with which a multilayer fibrous web 1 is formed.
- the multilayer fibrous web 1 in this case consists of a white cover layer 1a and a backsheet 1b.
- a pulp suspension is applied to the screen 16 via the head box 14 and dehydrated.
- a pulp suspension is also applied to a wire 15 and drained from a headbox 15.
- the formation of the supine position 1b is supported in the present example with a twin-wire former 10.
- the backsheet 1b passes through the twin-wire former 10 embedded between the two wires 13 and 12.
- the two wires 12, 13 and the backsheet 1b are deflected downwards via a deflection roller 11 and fed to the skin roller 17, which is vacuumed in the present example.
- the couch roll 17 covers the backsheet 1b with the white topsheet 1a in such a way that the white cover layer 1a forms the underside of the multilayer fibrous web 1.
- a suction box 4 is arranged, through which a vacuum dewatering upwards. Dirty water from the supine 1b is thereby sucked off, without it can get into the white cover layer la.
- the suction box 4 the upper wire 13 is lifted from the rubberized fibrous web 1, the separating sucker 18 prevents lifting of the fibrous web. 1
- FIG. 2 now also shows the subsequent to the former section 2 press section 3.
- the multi-ply fibrous web 1 is here fed to a first press nip 5 in free train. There, the multi-ply fibrous web 1 between two press rolls 8, which are each surrounded by a press felt 9, drained. In a further last press nip 7, the multilayer fibrous web between the two press rolls 8 and 19 is dewatered. In this case, only the upper pressure roller 8 is felted, so wrapped by a felt 9. The lower press roll 19 is a smooth untwisted roll. The white cover layer la comes here so only with the smooth surface of the press roller 19 in contact. Subsequently, we transferred the multi-layer fibrous web 1 in the drying section 20 and dried on the drying wire 25 by means of drying cylinders 21.
- FIG. 3 another possible embodiment of the press section 3 is shown.
- This is a TriNip press.
- the multilayer fibrous web 1 is here transferred from the wire 16 of the former section 2 directly to the press felt 22 and dewatered in a first press nip 5.
- the two press rollers 27 and 28 of the first press nip 5 are each surrounded by a press felt 22 and 23.
- the pulp 1 is further dewatered in a second press nip 6.
- This second press nip 6 is formed by the felted press roll 27 and the smooth central roll 30.
- a third and last press nip 7 between the smooth central roll 30 and the press roll 29, which is wrapped by a press felt 24, the last pressing before the fibrous web 1 is transferred by means of a suction roll 26 to the dryer fabric 25 of the drying section 20.
- the white cover layer 1a comes in the last press nip 7 thus only with the smooth surface of the central roller 30 in contact.
- FIG. 4 is one opposite the FIG. 3 modified TriNip press shown.
- the central roller 31 is wrapped by a smooth transfer belt 32, on which the multi-layer fibrous web 1 is transferred to the last press nip 7 by means of a suction roller 26 to the dryer fabric 25 of the dryer section 20.
- the white cover layer la in the last nip 7 comes only with a smooth pressing surface, namely with the smooth transfer belt 32 in contact.
- FIG. 5 shows a further press configuration with two press nips 5 and 7.
- the multilayer fibrous web 1 with the downwardly facing white cover layer la is transferred here from the screen 16 onto the press felt 33 and dewatered in the first press nip 5 between the two press rolls 8. Both rollers 8 are wrapped by a press felt 33 and 34, respectively. Following the first press nip 5, the fibrous web is transported further on the felt 34, transferred to the further press felt 35 and further dewatered in the last press nip 7 before the drying section 20.
- the last press nip 7 is formed here by the two press rolls 8 and 19, the roll 8 being felted and the lower press roll 19 being un-felted. From the smooth surface of the press roller 19, the fibrous web 1 is then transferred by means of the suction roller 26 on the drying wire 25. The fibrous web 1 is continuously supported in this press section 3.

Description
Den Gegenstand dieser Erfindung bildet ein Verfahren zur Herstellung einer mehrlagigen Faserstoffbahn mit einer weißen Decklage, gegebenenfalls einer oder mehreren Zwischenlagen und einer Rückenlage. Die einzelnen Lagen der Faserstoffbahn werden dabei in einer Formerpartie gebildet und miteinander vergautscht, sodass die weiße Decklage die Unterseite der mehrlagigen Faserstoffbahn bildet. Anschließend wird die mehrlagige Faserstoffbahn in einer Pressenpartie entwässert.The subject of this invention is a process for producing a multilayer fibrous web with a white top layer, optionally one or more intermediate layers and a supine layer. The individual layers of the fibrous web are formed in a forming section and vergautscht together so that the white cover layer forms the bottom of the multilayer fibrous web. Subsequently, the multilayer fibrous web is dewatered in a press section.
Bei diesen mehrlagigen Faserstoffbahnen handelt es sich in erster Linie um weißgedeckte Testliner (gestrichen oder ungestrichen) auch bekannt als White Top Testliner bzw. um weißgedeckten Kraftliner (White Top Kraftliner) bzw. um weißgedeckten Krafttopliner (Kraft Top White), oder um Gipskarton (Paster Board Liner), Faltschachtelkarton auf Altpapierbasis (White Lined Chipboard), Flüssigkeitskarton (Liquid Packaging Board), oder um Faltschachtelkarton auf Frischfaserbasis (Folding Box Board).These multi-ply fibrous webs are primarily white-covered testliner (coated or uncoated) also known as white top testliner or white-topped kraftliner (White Top Kraftliner) or white-covered Krafttopliner (Kraft Top White), or plasterboard (Paster Board Liner), paperboard carton, white lined chipboard, liquid packaging board, or folding box board.
Bei bestehenden Papiermaschinen hat es sich als günstig erwiesen, wenn nach dem Vergautschen die weiße Decklage die Unterseite der mehrlagigen Faserstoffbahn bildet ("Upsidedown-production"), weil in der nachfolgenden Pressenpartie insbesondere die Unterseite der Faserstoffbahn geglättet wird. Eine glatte weiße Decklage ist eine Grundvoraussetzung bei vielen Herstellungsverfahren. Die Rückenlage und gegebenenfalls auch die Zwischenlagen bestehen aus Fasern die eine geringer Weiße als die weiße Decklage aufweisen.In existing paper machines, it has proved to be advantageous if after Vergautschen the white cover layer forms the underside of the multilayer fibrous web ("upsidedown production"), because in the subsequent press section in particular the underside of the fibrous web is smoothed. A smooth white top layer is a prerequisite in many manufacturing processes. The supine and possibly also the intermediate layers consist of fibers which have a lower whiteness than the white cover layer.
Wenn die weiße Decklage die Unterseite der mehrlagigen Faserstoffbahn bildet, ergeben sich jedoch auch Probleme.However, when the white liner forms the bottom of the multi-ply fibrous web, problems also arise.
Nach dem Vergautschen der mehrlagigen Faserstoffbahn muss das Obersieb von der Faserstoffbahn abgehoben werden und die Faserstoffbahn am Untersieb weiterlaufen. Damit dies zuverlässig funktioniert, befindet sich unter dem Untersieb ein Trennsauger, der dafür sorgt, dass die Faserstoffbahn am Untersieb haften bleibt und nicht mit dem abhebenden Obersieb mitläuft. Häufig sind auch noch im Untersieb weitere Saugkästen angeordnet, durch die die vergautschte Faserstoffbahn weiter entwässert wird. Die Saugwirkung des Trennsaugers bzw. der unten liegenden Saugkästen saugt jedoch auch schmutziges Wasser aus der Rückenlage in die weiße Decklage, die dadurch an Weiße verliert.After covering the multilayer fibrous web, the upper sieve must be lifted off the fibrous web and the fibrous web must continue to run on the lower sieve. For this to work reliably, there is a vacuum cleaner under the lower sieve, which ensures that the fibrous web adheres to the lower sieve and does not run along with the lifting upper sieve. Often even more suction boxes are arranged in the lower sieve, through which the vergautschte fibrous web is further dehydrated. However, the suction effect of the vacuum cleaner or the bottom suction boxes also sucks dirty water from the supine position in the white top layer, which thereby loses whiteness.
Aufgabe der vorliegenden Erfindung ist es, ein Herstellungsverfahren zur Herstellung einer mehrlagigen Faserstoffbahn mit glatter weißer Decklage zu offenbaren, bei dem die Weiße der Decklage gegenüber herkömmlicher Verfahren verbessert wird.The object of the present invention is to disclose a production method for producing a multilayer fibrous web with a smooth white cover layer, in which the whiteness of the cover layer is improved over conventional methods.
Gelöst wird diese Aufgabe durch ein Herstellungsverfahren gemäß Patentanspruch 1. Also um ein Herstellungsverfahren bei dem direkt nach der Vergautschung eine Vakuumentwässerung nach oben erfolgt. Diese Vakuumentwässerung nach oben saugt das Siebwasser aus der unten liegenden weißen Decklage durch die Rückenlage hindurch aus der Faserstoffbahn. Ebenso wird das schmutzige Siebwasser aus der Rückenlage nach oben gesaugt. Dadurch wird verhindert, dass schmutziges Wasser aus der Rückenlage in die weiße Decklage gelangen kann. Beim nachfolgenden Trennsauger erfolgt dann zwar ein Saugen nach unten, jedoch ist dann die Rückenlage schon so weit entwässert, dass kaum noch Wasser in die weiße Decklage gesaugt werden kann. Gegenüber herkömmlicher Herstellungsverfahren erhält man so eine hochwertigere weiße Decklage.This problem is solved by a manufacturing method according to
Dieses Herstellungsverfahren eignet sich besonders gut für die Herstellung von White Top Testliner, White Top Kraftliner, Kraft Top White Liner, Plaster Board Liner, White Lined Chipboard, Liquid Packaging Board oder Folding Box Board.This manufacturing process is particularly well suited for the production of White Top Testliner, White Top Kraftliner, Kraft Top White Liner, Plaster Board Liner, White Lined Chipboard, Liquid Packaging Board or Folding Box Board.
Die nach oben gerichtete Vakuumentwässerung nach dem Vergautschen erfolgt vorzugsweise mit Hilfe eines oberhalb der Faserstoffbahn angeordneten Saugkastens. Dieser Saugkasten ist also im Obersieb angeordnet, er kann auch mehrzonig ausgeführt sein.The upward vacuum dewatering after gassing preferably takes place with the aid of a suction box arranged above the fibrous web. This suction box is thus arranged in the upper sieve, it can also be made mehrzonig.
Es ist vorteilhaft, wenn die mehrlagige Faserstoffbahn die nachfolgende Pressenpartie so durchläuft, dass die weiße Decklage zumindest in einem Nip, vorzugsweise im letzten Nip, nicht in Kontakt mit einem Pressfilz gebracht wird. Die weiße Decklage wird also mit einer unbefilzten Presswalze oder einem glatten Transferbelt in Kontakt gebracht.It is advantageous if the multilayer fibrous web passes through the subsequent press section such that the white cover layer is not brought into contact with a press felt, at least in one nip, preferably in the last nip. The white cover layer is thus brought into contact with an unfilled press roll or a smooth transfer belt.
Es ist günstig, wenn die Rückenlage in einem Doppelsiebformer gebildet wird. Dabei kann die Rückenlage im Doppelsiebformer über eine Umlenkwalze nach unten umgelenkt werden, wobei die Umlenkwalze von beiden Sieben des Doppelsiebformers umschlungen wird. Durch das Umschlingen der Umlenkwalze wird ein Abheben bzw. Abschleudern der Rückenlage vom Untersieb verhindert.It is favorable if the supine position is formed in a twin-wire former. In this case, the supine position in Doppelsiebformer be deflected by a guide roller down, wherein the guide roller is wrapped by two wires of Doppelsiebformers. By looping the guide roller lifting or spinning the supine position of the lower wire is prevented.
Zusätzlich kann die Umlenkwalze auch besaugt sein.In addition, the guide roller may also be sucked.
Wenn die mehrlagige Faserstoffbahn aus mindestens drei Lagen besteht, die nacheinander miteinander vergautscht werden, ist es vorteilhaft, wenn die erfindungsgemäße Vakuumentwässerung nach oben erst direkt nach der letzten Vergautschung erfolgt.If the multi-ply fibrous web consists of at least three layers, which are successively laped together, it is advantageous if the vacuum dewatering according to the invention takes place only directly after the last embedding.
Es ist auch denkbar, dass die weiße Decklage und/oder die Rückenlage mit Hilfe eines Mehrschichtstoffauflaufs auf ein Formiersieb aufgebracht werden. Wenn die weiße Decklage mit Hilfe eines Mehrschichtstoffauflaufes auf das Sieb aufgetragen wird, so soll die Schicht der weißen Decklage, die letztendlich die Oberfläche der mehrlagigen Faserstoffbahn bildet, die größte Weiße aufweisen.It is also conceivable for the white cover layer and / or the backsheet to be applied to a forming fabric with the aid of a multi-layer casserole. When the white top layer is applied to the screen by means of a multi-layer casserole, the layer of the white top layer which ultimately forms the surface of the multi-ply fibrous web should have the largest whiteness.
