Definitions

  • the invention relates to a device for producing a multilayer paper or cardboard with a primary longitudinal screen and a secondary longitudinal screen as a twin wire former, which device deposits one layer of the multilayer paper or cardboard on another layer, the twin wire former forming roller as a deflection roller for the course of the twin wire has and a strip former is arranged in the running direction of the twin wire in front of the forming roller.
  • the twin wire former is made possible by the fact that an upper wire runs onto the secondary longitudinal wire and the paper or cardboard layer lying on it.
  • gap strength problems can arise, i.e. problems with regard to the adhesion between the layers when a primary longitudinal screen is operated with a secondary longitudinal screen and a shoe former, similar to a so-called hybrid former, is seated on one of the longitudinal screens.
  • a high vacuum in the shoe is required for a perfect separation of the top wire from the web. This leads to high dry contents of the web, which are detrimental to good cleavage.
  • the French published patent application FR 2 388 936 shows a device of the generic type in which drains are drained heavily through the bottom wire in front of the twin wire area, as a result of which the gap strength that can be achieved with the top of the web is lower.
  • the drainage effective area on both sides is relatively short.
  • the possible dewatering effect on a - closed - forming roll is mentioned, but this is not used in such a way that the nip resistance is increased, but mainly because then other effects not to be considered here can occur.
  • the invention has for its object a device of the beginning to create the type mentioned, in which the advantages of influencing the formation, the high gap strength, the plybond, in addition to being insensitive to a jagged waterline and non-adjustable strips through sieve tubes, while reducing the sieve length and length of this paper machine section are present.
  • a suction box is arranged in the area of the top wire of the twin wire former and in that the water line of the fibrous material lies on the forming roller.
  • the waterline is the location of the fiber layer at which leaf formation is completed.
  • the dry matter content of the web is usually approx. 5 to 8%.
  • this water line is visible, namely where the transition from gloss through moisture to the lackluster appearance of the top of the fibrous web lies.
  • the waterline need not necessarily be a straight line. It is also a wavy, non-jagged form of this water line that should be considered.
  • the pressure bar former creates a shortened four-wire section in the area of the twin wire former, where dewatering can take place in the range of 10 to 20% of the total water, in connection with better formation and a control of the fine material distribution upwards.
  • a dry content of 8 to 15% is preferably present.
  • both screens of the twin wire former are in front of the forming roller run at least partly together essentially horizontally and optionally also after the forming roll at least partly together essentially vertically or also obliquely downwards.
  • the bar former When the twin wire runs horizontally in the area of the formation, there is a suction box above the top wire and below the bottom wire the bar former.
  • This can advantageously be designed as a pressure bar former, that is to say with bars that can be pressed towards the sieve.
  • the combination enables in the smallest space a good formation.
  • the undesirable two-sidedness with a high filler content, such as for example with waste paper, will be very low.
  • Rollback swirls in front of the forming roller are also prevented.
  • the solution according to the invention provides external drainage (20 to 30%) through the pressure bars and the suction box in the top sieve.
  • the material running over the forming roller after this formation section has the water line there on the forming roller and, particularly because of the deflection with relatively high moisture on the rubber side, comes to the other layer running below (primary sieve). Because of the high humidity when the webs collapse, the gap strength is correspondingly high.
  • Both a straight and a convex contour are possible as a shoe shape.
  • the shoe can be equipped with and without a pressure bar in the bottom sieve.
  • the drawings show a primary screen 10 which moves from right to left in accordance with arrow A in the drawing.
  • a deflection roller 12 for the primary longitudinal screen there is a headbox 14 for a lower layer of the multilayer paper.
  • the primary seal can also be designed as a hybrid former.
  • twin-wire former as a secondary screen arrangement with a lower screen 16 and an upper screen 18.
  • the screens move from left to right according to arrow B in the drawing, i.e. the bottom wire 16 around a deflecting roller 20 in the area of the headbox 22, a forming roller 24 (here an forming roller) and further rollers 26.
  • the top wire moves around a series of deflection rollers 28 and together with the bottom wire 16 around the forming roller.
  • the upper wire 18 and lower wire 16 move partially together in the horizontal direction in front of the forming roller 24 and behind the forming roller 24 at least partially together essentially in the vertical direction after the forming roller (in the running direction).
  • the dewatering or the formation of the material is set in such a way that the so-called water line lies on the dewatering roller 24, with the result that, in particular because of the deflection, the material with relatively high moisture on the rubber side meets the other web layer running below.
  • a trough 31 is attached to drain the water. Because of the high humidity when the web collapses, the gap strength is correspondingly high.
  • the embodiment according to FIG. 2 differs from that according to FIG. 1 only in the other assignment of the twin wire former to the primary longitudinal wire in that that the headbox for both layers is on the same side of the system.
  • the headbox for both systems takes place on opposite sides.
  • the device shown in FIG. 3 is equipped with a further former 29 in the area of the wire, whereby a so-called hybrid former is formed.
  • the additional former 29 has a screen 19 which is guided around deflection rollers 27.
  • the sheet formation area of the primary longitudinal screen 10 can also be approximately as high as that of the secondary longitudinal screen 16.
  • the multilayer sheet formed in this way can then be deposited on a further fourdrinier wire 10 'after a web has already been formed thereon with the aid of the headbox 14'.
  • the top wire 18 of the twin wire former wraps around the forming roller 24 by about 120 degrees, in FIG. 7 it is about 40 degrees.
  • other possibilities are also conceivable for carrying out the invention.
  • the suction box 32 can also be curved on its side facing the sieve, so that this results in advantageous convex guidance of the twin sieve with correspondingly curved strips 30 (FIG. 9).
