Definitions

  • This invention relates to a method of making a symmet­rical three-layer paper, more precisely a paper made of two heterogeneous stocks, preferably in that one stock forms the top layers of the paper and the other stock forms the intermediate layer thereof. It is known since long to make paper of several layers, especially at the manufacture of cardboard and kraft liner, i.e. for products having a grammage exceeding 100 g/m2. In most cases this is carried out in such a way., that the layers are formed separately and at a sufficient dry solids content are pressed together to bring about a multi-layer structure, so-called separate forming.
  • the advantages of this manufacturing method are - good control of the fibre distribution in the different layers - good possibilities of preventing admixture of fibres in the different layers - great possibilities of varying the grammage range by the number of layers and grammage/layer.
  • the disadvantages are - difficulty of maintaining the internal bond strength at more than two layers - higher capital costs.
  • Another method of making multy-layer paper is the so-called co-forming. This takes place in stratified head boxes, which implies that different stocks are ejected simultaneously through separate nozzles and form a combined jet out of the head box. Hereby, however, a considerable mixture of fibres between the layers can be obtained, and there are no possib­ilities of separating the white water.
  • This method does not yield advantages as great as the separate forming in respect of fibre control and grammage flexibility, but the capital costs are lower, and the decrease in internal bond strength at more than two layers is less great. It is, thus, previously known to use multi-layer head boxes where all layers are formed simultaneously.
  • the Figure in said specification shows an arrangement for the manufacture of a three-layer paper, comprising an inner wire 1 and an outer wire 4. From a head box 9 stock is ejected on the wire 1 and dewatered, where­after stock from another box 10 is ejected on the web, and additional dewatering is carried out by means of a roll 2, and the two layers are passed between the inner and the outer wire.
  • the second surface layer is formed of pulp suspension from a third head box 14 on a wire 8 and combined with the two other layers at the turning roll 7.
  • the two top layers and substantially half the intermediate layer shall be formed by co-forming from two separate head boxes, and the two layers then are combined by separate forming.
  • the method according to the invention is especially suitable for use at the manufacture of high-quality fine paper, especially suitable for copying in xerography. According to the invention, only two separately formed layers are required for bringing about a three-layer structure. At the method according to the invention, a top side is pressed against a top side, which yields good symmetry and a better internal bond strength than at co-forming where dewatering occurs in both dir­ections.
  • the invention also renders it possible to permit high hydrodynamic flows, because the number of layers in a box is restricted to two, and the dewatering distance can be adjusted to the dewatering demand. It is hereby possible to use low concentrations in the intermediate layer, and a high proportion of short fibres, possibly with high beating degree, in the outer layer in order to obtain a good surface. The low concentration makes it possible to form a paper with good appearance and long fibres (softwood).
  • the invention therefore, can combine multi-layer technique with increasing possibilities of using long fibres. At present at least 50% hardwood is used in fine paper. By using the above technique it shall be possible to freely choose the proportions of long fibres and short fibres in the intermediate layer and thereby reduce substantially the dependence on wood at the making of a fully satisfactory fine paper.
  • the bending stiffness can come close to the theor­etical level of a layer structure. This implies an improvement of about 20% of the bending stiffness at a fibre mixture of 50% birch fibre and 50% long fibre.
  • the high-beaten short fibre on the surface yields a high smoothness, which reduces the demand of glazing.
  • the intermediate layer filling agent can be applied to reduce the risk of sediments and wear from the paper surface.
  • the method according to the invention yields a paper with - higher bending stiffness - higher symmetry - free choice of fibre mixtures possibility of high filling agent proportion.
  • the intermediate layer is formed at low head box concentration, and the outer layer is formed at a higher one.
  • the Figure shows a wire 15 running over the breast rolls 13,14.
  • a head box 1 with layers 2 and 3 the stock for one top layer is passed through 3 and half the grammage for the intermediate layer through 2 in order to form the co-formed web 18 on the wire.
  • Dewatering takes place at 16.
  • the head box 4 which also comprises two layers 5 and 6, the stock is passed in the same way for the top layer through 5 and about half the grammage for the intermediate layer through 6.
  • the resulting web 20 is dewatered at 10 through the wire 19.
  • the wire with the web 20 then runs over the roll 9 and is separately formed with the web 18 at the press roll 12.
  • the complete thre-layer paper then consists of the top layers 21 and 23 and the intermediate layer 22.
