117868

The invention relates to a method and a multi-roll calender for calendering a glossy and / or matte-coated fibrous web, such as paper or board.

In particular, the invention relates to, but not limited to, the calendering of a glossy and matte-coated fibrous web, such as paper or cardboard, in a multi roll calender with 10 or more rolls, at least a portion of which is provided with a calenderable web.

As is known, high-gloss paper and board grades are finally calendered with a multi-roll calender.

With respect to the prior art, reference is made to FI Patent Publication 96334 which discloses a method for calendering paper or similar web material in a calender and a calender applying the method. According to the publication, the calendering ♦ / ·· web material is passed through nip formed by a deflection compensated top roll and deflection compensated ·· «: ... ϊ 20 and two or more intermediate rolls arranged between the top and bottom rolls. Intermediate rolls are rolls with their own · · -i:. ·; the shape of the natural deflection line caused by weight is substantially * similar. The * · »nip load caused by the masses of the intermediate rolls and associated auxiliaries is substantially alleviated in the method and the adjustable load is applied to the calendering nips by deflection compensated upper roller or lower roller and / or external roller load on upper or lower roller.

Calendering technology is increasingly switching to on-line calendering as the speeds required by paper machines increase. Multi-nip on-line calendering is calendering in a calender unit in which the nips are formed alternately between successive smooth-faced press rolls, such as a metal roll, and a roll coated with a flexible coating, such as a polymer roll, and / or a pivoting nip. In multi-nip calenders, the line load increases from the upper nip to the lower nip due to the earth's pulling power, unless roller lightening systems are used. To eliminate downward line pressure, roll; In the present multi-nip calendars, a roller-compensating roll relief provided by a cylinder and a lever mechanism is used to control the deflection line as well as for quick opening of the roller. Such a roll relief system is used under the applicant's OptiLoad and TwinLine trademarks. . in known multi-roll calendars.

1 .. * Reprinting of the matte texture is effected by the compression of the fiber web 11 φ φ φ · »· 117868 3. In said two-nip soft calender, the order of the rolls is reversed in successive nipples such that both sides of the web are in turn calendered against a single heated matte hard roll. This rigging produces 5 high quality smooth matte finishes, but the soft calender as a standalone calender is expensive.

The fibrous web can also be finally calendered with a separate two-nip soft calender where all rolls are polymer-coated. With this calendering mode, only a small amount of deformation can be achieved on the fibrous web, since it is a calendering nip formed between two soft rolls.

In this method, heat is not introduced into the process by polymer rolls. The method produces a relatively poor smoothness on the fibrous web. This arrangement does not achieve as smooth a matte finish as the previous option and is expensive to separate.

15 '

A separate soft nip in connection with a multi-roll calender is also known. In this separate soft soft nip, both rolls are polymer coated.

The smoothness of the final product calendered to a matte finish is not very good, but such a rigidity using rollers in a multi-roll calender is • · · * ... * 20 cheaper than calendering in a separate double nip soft calender.

• · * • · ····. · · »· • * • · ·; It is also known to produce a matte-coated fiber web in a · · multi roll calender by replacing the lowest thermal roll, e.g., the * * * · * · * calender roll with the lower roll, and running the paper only. 25 polymer clips. However, in this arrangement, changing the * · · • · * thermal roller to the polymer roll required for matte calendering is laborious and slow. In addition, • · · 11 *** roller contamination is a serious problem, as rolls that are not in contact with the web are contaminated with airborne particles in a situation where the * · * “· * web does not continuously protect the surfaces of the rolls in question and / or * · ·. * ·: 30 dirt removed. Thus, when cleaning rolls, the handicraft requires: ... · the export of the track to pass through these previously non-calendered rolls 117868 4. It has been found that the empty nipples, through which the web does not pass, develop static electricity which will spoil the surfaces of the web to be calendered unless the grounding in the calender works.

There is still known a multi-roll calender such as the one described above, in which a polymer roll has been replaced in place of the lowest thermal roll, and in addition a roll is locked to a fixed rotatable position. In this case, a lockable roller can be arranged to open some of the nipples and pass the web only through the soft polymer roller nipples. In this arrangement, changing the thermal roller to the 10 polymer rolls is laborious and slow, and the contamination of rolls not involved in calendering is problematic. The attainable line load level is modest, which means that the smoothness of the mat calendered end product is not very good either.

The object of the present invention is to prevent the above problems and shortcomings, or at least to reduce the above disadvantages, or to provide an alternative way of producing a glossy and good quality matte fiber web.

It is an object of the invention to provide a method and a multi-roll calender for producing a glossy and * φ «* ... * matte fiber web.

The invention provides significant advantages over prior art solutions, and among these benefits, the following may be mentioned. The same multi-roll calender can be used for calendering both high-gloss and high-quality smooth matt grades. In other words, no other separate equipment suitable for final calendering 5 is needed. This will result in lower costs compared to, for example, a separate mat calender. With the same multi-roll calender, rapid species conversion can be achieved, and at the fastest, only a new threading is sufficient to effect the species conversion. According to the solution of the invention, the traceable double-sided calendering of the web against the heated matte-hard hard roll enables the calendering of a high-quality, high-quality matte-type fibrous web with a multi-roll calender.

With respect to other features and advantages of the invention, reference will be made to the dependent claims and to the following specific part of the specification, which describes in detail, but by way of example only, preferred embodiments of the invention and their embodiments.

In tracks, adjacent calender rolls 11.12; 12.13; 13,14 to 18,19 and 19,20 form calender roll pairs, wherein each of the calender rolls forms a nip 1-9 with the reference marks in Figures 1-4 from top to bottom. In Figures 1-3, each of the nipples 1-9 of the rollers 10a, 10b and 10c is calendered with a fiber web W, whereby all of the nips 1-9 are closed during calendering. The nipples that are not involved in calendering the fibrous web W or some of them may also be open. This may be the case, for example, if the number of nips is more than six.

In Figure 4, the fibrous web is calendered only in a portion of the nip 10d bits, whereby the nips not involved in the calendering Wd 10 are closed, i.e. all the nip 10d calendering rolls are in nip contact. The nipples that are not involved in calendering the fibrous web W or some of them may also be open.

Here, the invention has been described using, for example, a 10-roll track 1510a-10d, with nine consecutive nipples, but any other larger number of rolls in the multi-roll calender 100 may be equally suitable, the preferred number of track rolls being at least nine. pieces.

One example of a calender in which the invention can be applied is a super calender comprising more than ten calender rolls. The * · · 20 may also be an application of the track described in connection with the invention to the single roll multi-roll calender 100 · · * · in a two-roll multi roll roll calender.

In the multi-calender, the upper roll and / or lower roll may be provided with a loading apparatus arranged inside the diaper and / or the upper roll may be loaded with an overhead loading cylinder and / or the lower roll may be loaded with a lower loading cylinder. The deflections of the rolls can be compensated by deflection compensators on the rolls, for example, so that the deflection lines of the rolls are of approximately the same shape. The deflection compensating devices are typically provided in the upper 10 and / or the lower roll, but also one or some of the intermediate rolls may be provided with deflection compensating means.

In the schematic side view of the roller assembly 10a of the multi-roll calender 100 shown in Figure 1, the shaft web W is calendered to produce glossy species in all nipples 15 between the calender rolls with the track extension from top to bottom. The fibrous web W is guided through an output roller 21 to the upper nipple 1 and further through the other nipples 2 to 8 of the roller 10a and finally out of the lower nip 9. Between nipples 1-9, web W is removed from the surface of the rolls by the take-up rolls 22,23,24,25, 26, 27, 28 and 29.
