Definitions

  • the invention pertains to a fiber web machine and to a method of forming a multiply web.
  • Document WO 99 / 40 256 A1 discloses an arrangement of three forming sections each of which having a wire guided about rolls in a closed loop and a multi-layer headbox.
  • the closed loops of the wire are guided such that liquid layers ejected on and conveyed by the wires are dewatered to form plies and then are merged such that the at least three plies occurring from the liquid layers ejected by the multi-layer headbox are sandwiched between the at least two other plies.
  • document WO 99 / 40 256 A1 discloses a web forming method using the above-described arrangement.
  • Document EP 2 784 213 B1 discloses a multi-layer headbox structure for a fiber web machine which serves to supply mainly liquid substances such as water and/or a pulp suspension liquid in a layered manner onto a wire of a forming section.
  • Additives such as refined fibers, fillers, cationic polymers such as cationic starch, etc. are added to the water and/or pulp suspension liquid.
  • These liquid substances are fed to the headbox by means of a water supply or feed water supply.
  • a central diffuser of the headbox is connected with feeding means feeding fresh water, dilution water, and/or white water into the central diffuser
  • the substances applied onto a forming wire are then dewatered to form a web. This is then further transferred to a press section for additional dewatering and a dryer section in which the formed web is dried to form a paper or board web. Further treatment depends on the respective requirements of the product.
  • Fig. 1 shows an example of such a headbox structure.
  • a fiber web machine comprises at least three forming sections. Each of these forming sections has a wire guided about rolls in a closed loop, and a headbox adapted to eject at least one layer of liquid onto the respective wire. At least one of the headboxes is a multi-layer headbox adapted to eject at least three liquid layers onto the respective wire. A center diffuser of the multi-layer headbox is connected with feeding means for feeding fresh water, dilution water and/or white water.
  • the closed loops of the wire are guided such that liquid layers ejected on and conveyed by the wires are dewatered to form plies and then are merged such that the at least three plies occurring from the liquid layers ejected by the multi-layer headbox are sandwiched between the at least two other plies.
  • the feeding means supplying the center diffuser of the multi-layer headbox can be additionally connected with a starch storage in order to supply starch with the fresh water, dilution water and/or white water.
  • the middle layer plies can be optimized in order to maximize the bulk of the web.
  • the middle layer can be divided in two separate stock layers separated by the water layer.
  • brightness levels of the layers can be individually adapted. Thus, for example when applying higher brightness to the ply next to the top ply, less bleaching is required.
  • increase of the bulk is possible. For instance, the increase of the bulk can be in a range of about 15% to 30%.
  • the fiber web machine can be used for manufacturing Folding Boxboard.
  • a method of forming a multi-ply web in a fiber web machine comprises the steps:
  • a web can be formed which has middle plies the properties of which can be advantageously adapted as desired by means of one multi-layer headbox, while the web is completed by separately formed top and back plies, respectively.
  • starch can be added to the fresh water, dilution water, and/or white water guided through the central diffuser of the multi-layer headbox.
  • middle layer's stocks By adapting the starch level, properties of the middle layer's stocks can be advantageously optimized with regard to the bulk.
  • the middle layer plies can be optimized in order to maximize the bulk of the web.
  • the middle layer can be divided in two separate stock layers separated by the water layer.
  • coarser fibers can be used in the middle layer. Accordingly, less refining is required for the fibers and the bulk can be increased. It is even possible to use different refining rates between the top and back ply sides. Also, brightness levels of the layers can be individually adapted. Thus, for example when applying higher brightness to the ply next to the top ply, less bleaching is required. Thus, increase of the bulk is possible.
  • the starch can be preferably added with an amount of 1 to 20 kg per ton of water, and most preferably with an amount of 2 to 10 kg per ton of water.
  • the bulk of the middle layer(s) can be maximized.
  • the pulp suspension comprise BCTMP (Bleached Chemi Thermo Mechanical Pulp), CTMP (Chemi Thermo Mechanical Pulp), TMP (Thermo Mechanical Pulp), PGW (Pressurized Ground Wood) and/or GW (Ground Wood), wherein the pulp suspensions guided to the one or more of the adjacent diffusers of the multi-layer headbox have a different composition.
  • broke can be added to the pulp suspensions fed to one or more of the adjacent diffusers of the multi-layer headbox, wherein the amount of broke preferably differs in the individual pulp suspensions.
  • a brightness of one of the plies of the web is higher than a brightness of the other one of the plies of the web.
  • the middle layer can be divided into two layers, both of these layers can be given different properties, e.g. by using different refining rates for the added fibers. Thereby, coarser fibers can be used which advantageously leads to a higher bulk. Also, different brightness levels can be assigned to the middle layers, leading to that less bleaching is required which is also advantageous with regard to the bulk.
  • the manufacturing cost of such kinds of multiply products is achieved by dividing the middle ply stock in two layers, and feeding chemicals to between these two layers by means of the aqua layer. Then it is possible to use coarser fibers in the middle ply (which means less refining and therewith smaller energy consumption) and to also reduce bleaching chemicals consumption (the bottom side stock of the middle layer can have a smaller brightness than the top side stock). Mainly this is achieved by feeding starch between to these two layers and starch feeding happens by this central diffuser by water (fresh water, white water, or dilution water).
  • the invention can be preferably used in FBB (folding box board) production.
  • FBB folding box board
  • FBB folding box board
