Definitions

  • the invention relates to a machine for producing a multi-ply fibrous web, in particular a board web, having a forming region comprising at least two layer forming regions for forming the fibrous web layers for forming the multi-ply fibrous web and having a pressing region adjoining the forming region ,
  • the invention also relates to a method for producing a multilayer fibrous web, as well as the use of the machine.
  • the document EP1780332 A1 describes a machine for producing a board web.
  • the board web of 4 fibrous web layers, which are each formed in Lagenformier Schemeen, produced in the forming area.
  • the further dewatering by roll pressing in a pressing area.
  • the drying takes place in a subsequent drying section.
  • a Yankee cylinder is provided within the dryer section.
  • a broad nip calender is installed to further improve the smoothness of the board web. This is followed by a coating device for applying a stroke to one side of the board web, followed by final drying and reeling of the board web.
  • the object of the present invention is to improve the known manufacturing process for a paper and board web in terms of their quality and its cost-effectiveness.
  • Essential to the invention is that for dewatering a dewatering unit with a press zone through which the fibrous web and / or a fibrous web position between a circumferential, permeable belt and a circumferential, permeable support belt is passed, is provided, and wherein the pressing zone is formed such that the permeable band, the fibrous web and / or a fibrous web ply and the permeable support band, at least on a part of the Length of the press zone, can be flowed through by a fluid and the pressing zone is formed by a permeable pressing member and a permeable counter element.
  • the fibrous web is gently dewatered, wherein the applied mechanical dewatering pressure can be adjusted almost independent of the intensity of the flow through the fibrous web with the fluid.
  • the strength values of the multilayer fibrous web in particular the splitting strength, are improved.
  • the drainage is very volume-saving, so that the thickness of the fibrous web decreases less by the pressing process than in the known manufacturing processes. Since the thickness of the fibrous web substantially influences the mechanical strength, as for example in the case of a bending load, the mechanical strength of the fibrous web can be increased by the solution according to the invention or fiber material can be saved by reducing the basis weight with the same strength.
  • the solution according to the invention makes it possible to produce a paper or board web, in particular a folding carton web with a high specific volume and at the same time good smoothness.
  • the flow direction of the fluid is selected so that first the permeable pressing element, then the permeable band, the fibrous web or the fibrous web layer and then the permeable support band are flowed through.
  • the permeable pressing element is preferably a mechanical pressing element for forming a mechanical pressure on the permeable band and thus on the fibrous web.
  • the counter element is designed as a roller or a box with a curved or flat contact surface.
  • the roller is preferably a suction roller.

  • an external suction box may be provided for sucking the grooves. This results in an efficient flow guidance of the fluid through the press zone. Flow losses can be minimized.
  • the permeable pressing element consists of a press belt and / or a press shoe. If only one press belt is used as the press element, then it is conceivable to use a further press element, for example in the form of a roller or a press shoe, within the press belt loop. Thus, the mechanical dewatering pressure can be increased locally within the press zone.
  • the press shoe serves as a pressing element, it may be designed to be permeable or grooved and / or drilled in order to allow flow through the pressing zone with the fluid.
  • the press belt consists of a screen mesh, a spiral screen, metal mesh, perforated metal strip or a band of composite material, such as carbon fiber reinforced plastic.
  • the press belt has an air permeability of more than 100 cfm, in particular more than 200 cfm, where "cfm" indicates the cubic feet of air volume at a differential pressure of 125 Pa per square of the press belt in square feet and per minute flows through the press belt. The measuring procedure is described in the TAPPI T251 standard.
  • the area of the air permeability has the advantage that at a given differential pressure between the side facing away from the fibrous web side of the permeable support belt and the side facing away from the permeable belt side of the Pressbandes, a very high volume flow of fluid through the fibrous web can flow. Another advantage is that it keeps the mechanical pressure generated by the flow small.
  • the press belt is designed so that a tensile stress of more than 30 kN / m, in particular of more than 40 kN / m, in particular of more than 45 kN / m in operation of the machine is possible.

  • the diameter of the counter element is advantageously greater than 1 m, or the radius of curvature of the counter element is greater than 0.5m.
  • the permeable tape may have a structured surface for structuring the fibrous web and / or at least one fibrous web layer. This is especially true for fibrous webs which only need to be smooth on one side or for fibrous web layers which form an inner fibrous web layer of the multilayer fibrous web. This allows a high specific volume without compromising the quality of the fibrous web in terms of the required smoothness.
  • the permeable band is formed by a forming fabric.
  • Forming screens are designed marking poor. This is achieved by known weaves.
  • the weave structure has bases in relation to the fibrous web.
  • weaves are used which have more than 1300 support points per cm 2 , in particular more than 1400 support points per cm 2 , preferably more than 1500 support points per cm 2 . This has the advantage that a good smoothness is achievable.
  • the permeable band is formed by a felt.
  • the permeable band can be formed by a nonwoven, permeable band which is coated on the side touching the fibrous web.
  • the permeable band consists of a plastic band which preferably has an internal reinforcement made of a fabric band or a thread band.
  • the permeable support band is preferably formed by a felt. This can absorb at least a portion of the originating from the fibrous web water. In practical arrangements, the permeable support band may also be formed by a forming fabric.

  • three or more ply forming areas are provided in the machine.
  • the dewatering unit is disposed in at least one sheet forming area for an inner layer, wherein the supporting tape is formed by a forming wire of the sheet forming area.
  • This variant offers the possibility to produce a box with a high specific volume.
  • the permeable band may be a coarse, textured sieve. Since the fibrous web is arranged in an inner layer and thus covered by an outer layer, this arrangement also allows a good smoothness.
  • a hood may be provided within the loop of the press belt or the permeable belt.
  • the hood is supplied with the preferably hot fluid.
  • the hot fluid used is air and / or steam.
  • the hot air can advantageously come from the exhaust air of a drying unit of the paper machine, such as the hood exhaust air of a Glättzylinders.
