Definitions

  • the present invention relates to a sheet forming method and device, specifically a machine for the production of a multi-ply fiber web, such as a paper, or cardboard web, or a packaging paper web in which layers formed by a respective former are couched together.
  • a multi-ply fiber web such as a paper, or cardboard web
  • a packaging paper web in which layers formed by a respective former are couched together.
  • FIG. 2 illustrates the theoretically possible improvement of the basis weight (law of error propagation) in dependency on the number of plies. The improvement is around 30% if two layers are utilized instead of one layer. It can also be seen from FIG. 2 that the gain in the improvement diminishes with an increasing number of plies. In order to gain an additional 25% improvement, three additional plies are required.
  • Such formulations are based on the theoretical assumption that the quality of the individual paper webs remains constant and independent from the basis weight. In reality however, the numbers will vary.
  • FIG. 3 illustrates the operating window of a newer cylinder mold former.
  • Multi-ply endless wire machines combine the advantages offered by single endless wire machines with those of multi-ply cylinder mold machines. As seen in FIG. 4, the operating window of multi-ply endless wire machines is wider than that of cylinder molds.
  • the motivation for using multi-ply endless wire machines for the production of cardboard is the speed, resulting in increased production, and increased quality attributes, such as the creation of smoothness and flexural strength in the sheet or paper web.
  • FIG. 5 compares the operating window of multi-ply endless wire machines (zone “A”) with a single-ply Gapformer and a two-ply Gapformer.
  • single-ply Gapformers are highly competitive in the average speed range.
  • a sheet, or a web of 150 g/m 2 can, for example, be produced with only one Gapformer at a speed of 950 m/min. resulting in a production of approximately 205 t/(d-m). This is considerable for one former. Nevertheless, a second ply is essential for a high output.
  • Curve “C” illustrates the operating range for a two-ply Gapforming concept. Such a concept enables the production of a high sheet-square meter weight, even at high speeds.
  • Consistency is one of the determining factors for the production of corrugated board and base paper. Producing two plies instead of one results in a significant improvement in consistency. Even though the consistency may differ with different forming concepts, the multi-ply technology offers a clear advantage.
  • FIG. 6 shows the tear-length of a web of a 100% Old Corrugated Container (OCC) web for various basis weights, utilizing one or two Gapformers.
  • OCC Old Corrugated Container
  • a multi-ply Gapformer such as shown in FIG. 7, ensures optimum formation and consistency at the highest production speeds, whereby a compensation and averaging effect is utilized.
  • the present invention develops and optimizes the aforementioned concepts for complete paper machines, specifically packaging paper machines and more particularly creates a paper machine, which offers additional advantages in at least a part of the aforementioned areas.
  • the present invention is a sheet forming device, and specifically a machine for the production of a multi-ply fiber stock web, and more particularly a paper or cardboard web, or a packaging paper web.
  • the plies that are formed by respective formers are couched together and at least one of the formers, for forming a multi-ply web, includes a multi-ply headbox, which is furnished with at least two different stocks, or partial stock streams of different compositions for each ply.
  • the multi-ply headbox is furnished with at least two of the following stock fractions:
  • the long fiber fraction and/or the fraction having a low fines content are furnished to a first former; and the long fiber/short fiber fraction and/or the fines poor/fines rich fraction, as well as the short fiber fraction and/or the fines rich fraction are furnished to a multi-layer headbox of a second former.
  • the long fiber fraction and/or the fines poor fraction that is furnished to the first former form a liner layer.
  • the long fiber/short fiber fraction and/or the fines poor/fines rich fraction as well as the short fiber fraction and/or the fines rich fraction are furnished to a former including an outer and inner wire, in which the long fiber/short fiber fraction and/or the fines poor/fines rich fraction are dewatered by the outer wire and the short fiber fraction and/or the fines rich fraction are dewatered by the inner wire.
  • the long fiber fraction and/or the fines poor fraction form a liner layer.
  • a backing layer is formed by the long fiber/short fiber fraction and/or the fines poor/fines rich fraction, and a center layer is formed by the short fiber fraction and/or the fines rich fraction between the liner layer and the backing layer.
  • At least one of the formers is a Gapformer, including a forming element that is specifically in the embodiment of a forming roll.
  • the long fiber/short fiber fraction and/or the fines poor/fines rich fraction, as well as the short fiber fraction and/or the fines poor fraction are fed advantageously to a Gapformer in which the sheet is formed with the short fiber and/or the fines rich fraction on the forming element.
  • the machine may be specifically designated for the packing segment.
  • the machine includes a press section, a dryer section, at least one coating or applicator device and/or a rewinder.
  • At least one of the headboxes may be designed as described in DE 40 19 593 A1.
  • the press section may be designed as described in DE 40 26 021 A1.
  • An example of a dryer section is described in DE 42 18 595 A1.
  • a coating or applicator device may be designed as described in DE 34 17 487 A1.
  • a rewinder may used, as described in WO 98/52858.
  • the plies that were formed by a corresponding former are couched together.
  • At least one of the formers for forming a multi-ply web includes a multi-layer headbox which is furnished with at least two different stocks, or partial stock streams of different compositions for each ply.

  • FIG. 12 is an illustration of the effects of a layered web in the size press/Speedsizer of the present invention.
  • Multi-ply web 12 may specifically be a paper or cardboard web 12 .
  • two plies A and B are each produced by a respective former.
  • At least one of plies A and B is produced by a Gapformer, including forming element 14 in the embodiment of forming roll 14 .
  • Each Gapformer includes two endless dewatering wires that run together, forming stock infeed nip 30 and which are routed over respective forming element 14 , in this instance a forming roll 14 , in the area of stock infeed nip 30 .
  • the outer dewatering wire is brought to forming element 14 over breast roll 28 .
  • Stock infeed nip 30 is furnished with fiber stock suspension via a headbox.
  • first Gapformer 16 is provided for the forming of first ply A
  • second Gapformer 18 is provided for the forming of second ply B.
  • First ply A is delivered by the lower or base wire 22 of first Gapformer 16 , which is separated from top wire 20 , to couch section 24 in which plies A and B are couched together.
  • the direction of rotation of forming element 14 of second Gapformer 18 is the same as the direction of rotation of forming element 14 of first Gapformer 16 .
  • the layout can be arranged so, that opposite directions of rotation result.
  • First Gapformer 16 may, for example, be a “DuoFormer Base”-former and second Gapformer 18 may be a “DuoFormer Top”-former.
  • Headbox 30 of second Gapformer 18 is designed to be a multi-ply headbox, which is furnished with at least two different stocks or stock partial streams of varying composition for the different plies.
  • Multi-layer headbox 30 can be furnished with at least two of the following stock fractions:
  • the long fiber fraction and/or the fraction having a fines poor fraction may specifically be furnished to first former 16 .
  • the long fiber/short fiber fraction and/or the fines poor/fines rich fraction, as well as the short fiber fraction and/or the fines rich fraction may be furnished to multi-layer headbox 30 of second former 18 .
  • a liner layer is formed on base wire 22 by the long fiber fraction and/or the fines poor fraction that is furnished to first former 16 .
  • the sheet formation may occur specifically with the short fiber fraction and/or the fines poor fraction on the former element side. Consequently, the long fiber/short fiber fraction and/or the fines poor/fines rich fraction is dewatered by outer wire 20 and the short fiber fraction and/or the fines rich fraction is dewatered by inside wire 32 .
  • a liner layer is formed by the long fiber fraction and/or the fines poor fraction on base wire 22 .
  • a backing layer is formed by the long fiber/short fiber fraction and/or the fines poor/fines rich fraction and a center layer is formed by the short fiber fraction and/or the fines rich fraction between the liner layer and the backing layer.
  • Machine 10 may be specifically designated for the packaging segment.
  • FIG. 8 shows the relative location of the fractions during the dewatering process.
  • the long fiber/short fiber fraction and/or the fines poor/fines rich fraction is dewatered by outside wire 20 of second Gapformer 18 .
  • the short fiber fraction and/or the fines rich fraction, containing the largest amount of fines, is dewatered by inner wire 32 of Gapformer 18 .
  • a gentle dewatering by way of corresponding forming element 14 allows the fines in the short fiber fraction and/or the fines rich fraction to be retained in the web. This is desirable for various reasons, particularly for good ply bonding.
  • the long fiber/short fiber fraction and/or the fines poor/fines rich fraction on the side of outside wire 20 brings about a reduction in the wash-out effects.
  • LS Long fiber fraction and/or fines poor fraction as a liner layer on wire 20 .
  • FIG. 10 there is shown a schematic of press nip 34 .
  • a long fiber web and/or a fines poor fraction is significantly more open and easier to dewater than a short fiber web and/or a fines rich fraction. Since the long fiber fraction and/or the fines poor fraction and the long fiber/short fiber fraction and/or the fines poor/fines rich fraction are located on the outsides of the web, the water can be drawn off more easily. This counters web crushing in the press section, which is particularly important for a high production output. Better dewatering correspondingly increases the wet-densification, which is advantageous for the consistency development.
  • FIG. 11 there is illustrated long fiber fraction and/or the fines poor fraction opposite the dryer cylinders. Due to the better bonding of the longer fibers in the web, the development of dust in the dryer section is reduced. Reduced dust leads to increased runability and improved conversion characteristics.
  • Another advantage consists in that the long fiber/short fiber fraction and/or the fines poor/fines rich fraction comes into contact with the dryer wire. This fraction is very clean, with only a small portion of “stickies”. This leads to reduced contamination of the dryer wires, which is a positive factor for runability, as well as for cleanliness and maintenance.
  • High consistency values require full starch-penetration. At high speeds the dwell time in the nip is shortened and it becomes more difficult to maintain full starch penetration of the web in the press section.
  • the layered web structure of the present method facilitates dewatering.
  • the open surface of the layered web permits an increased starch penetration and the fines have a higher affinity for starch.
  • the high fines content in direction of the web center, supports the penetration process in that the starch is sucked toward the inside. This effect is particularly advantageous for high basis weights and high production.
  • the long fiber fraction and/or the fines poor fraction on the surface preserves a certain roughness, necessary in order to maintain the desired gliding angle.
  • the hot glue characteristics are improved in that the glue is better able to penetrate the surface, causing a mechanical anchoring with the web.
  • the present invention improves the efficiency of the machine, and the runability, as well as the web characteristics that are necessary for further conversion and the final application. Consequently, natural resources are utilized more efficiently, thereby serving the environment. The total costs per net registered ton of paper are reduced, thereby correspondingly increasing profits.
