Definitions

  • the invention relates to a flat structure, preferably to a screen belt or link belt for paper machines or the like. with a large number of coils made of elastic plastic or metal wire, which consist of opposing winding legs and head arches connecting them, in the spaces between which a head bow of the adjacent coil is inserted so far that an overlap area arises between the two coils, in which a Plug wire made of plastic or metal is arranged.
  • the wire coils have a tension in the form of a tension spring in such a way that the respectively adjacent wire coils are in contact with one another.
  • Such a wire link belt is intended to maintain its dimension elastically, in particular in the transverse direction. Furthermore, the technical progress of such a wire link belt is seen in the fact that production is simplified by the fact that the coils necessarily find their place when they are inserted into one another and cling to one another, so that complex devices can be avoided and that the connecting means no longer have to be stiff and heavy .
  • the coils do not have a tension preload and that the wire of the coils is torsion-free. This is intended to increase the lifespan of the fabric and ensure freedom from marking.
  • sealing rails or sheet metal inserts are also used in the last-mentioned flat structures, which are introduced in the longitudinal direction in the coils or in the spaces between adjacent winding legs.
  • the present invention has for its object to provide a fabric of the type described, which combines the advantages of easy manufacture from round wire coils with the advantages of large contact surfaces and good heat transfer and a limited air permeability.
  • the coils can be joined together to form flat structures just as easily - often even more easily - than coils made of round wire.
  • Only one spiral size needs to be provided for the automatic production of the flat structures on production (joining) machines.
  • practically all automatic manufacturing (joining) machines can easily produce flat structures with only one coil size.
  • the gaps between the individual winding legs can be large as required be designed smaller or smaller. Not only are advantageous, large, flat receiving surfaces of the supporting winding legs obtained, but also an air flow of the desired strength, without the disadvantageous use of fillers between the winding legs or within the coils.
  • the heat transfer for example from calender rolls through the sheet to the paper, also improves.
  • the new sheet-like structure is designed such that the turns of the spirals opposite the turns of the helixes that have the flat bearing surfaces have a round, oval or triangular cross-section.
  • the air permeability is only influenced by the load-bearing turn legs.
  • a further variation possibility of the air permeability with a good support for the paper results from the fact that both winding legs of the coils connected to a head bend each have flat contact surfaces. As a result, the air flow is opposed to a greater resistance than in the first embodiment.
  • the wires of the head arches of the coils have a substantially round, oval, triangular or rectangular cross-section, at most squeezed in relation to their original shape, and the winding legs, which have flat contact surfaces, have an almost rectangular cross-section.
  • the flat structures according to the invention are characterized in one exemplary embodiment in that the width of the turn leg having a flat contact surface is up to twice as large as the wire diameter or the wire width of the head bends.
  • the coils of the new flat structure are wound on division in such a way that the coils have a tension spring-like pre-tension, but the fixed space between their head arches is larger than their wire diameter or wire width. As a result, the head arches of adjacent coils do not lie against one another, even though the coils as such have a pre-tensioned tension.
  • spirals are alternately right-handed or left-handed spirals.
  • all coils of the flat structures can also be right-hand or left-hand coils.
  • the coils can be stored in collection containers before they are manufactured without them getting caught.
  • the turn legs form an angle different from 90 ° with the plug wires, whereas the head arches of the coils form an angle of approximately 90 ° with the plug wires.
  • the plug wires are preferably made of steel wire, so that the flat structures can be pulled apart to a greater or lesser extent via the spikes, for example in order to vary the passage of air.
  • the plug wires can also be made of plastic. As a result of the elasticity of the individual coils, the fabrics can be reduced to their original length as required.
  • the edge fastenings of some flat structures according to the invention also have reinforcements for attacking claws.
  • FIG. 1 shows a schematic overview drawing, in which a partial section of a flat structure generally designated 1 is shown.
  • the flat structure itself which is only shown in the cutout, can have any length and width.
  • the two vertical lines in the middle of the illustration are intended to indicate this schematically.
  • the flat structure consists of individual helices 2, which can be right-handed, for example, like the helix 3 or left-handed, like the helix 4.
  • Adjacent coils themselves are made from resilient plastic or metal wire in a manner not of interest in connection with the present invention. As shown in FIG. 10, they consist of supporting winding legs 7 and winding legs 8 lying opposite them. The winding legs are connected to one another by means of head bends 17.
  • FIG. 1 shows that there are spaces 18 between the individual head arches, into each of which a head arch of the adjacent coils is inserted. As a result, there is an overlap area 24 between two adjacent coils, as can be seen in FIG. 8, in which the plug wire 25 is inserted.
  • the head arches 17 of adjacent coils together with the plug wire 25 form an articulated hinge-like connection.
  • the plug wire 25, like the material of the coils, can be made of plastic or metal.
  • the supporting winding legs 7 lying on top in the plan view according to FIG. 1 have flat contact surfaces 12, the width 13 of which is greater than the wire diameter 23 or the wire width 23a of the head bends 17.
  • the space 18 between adjacent head arches 17 is larger than the wire diameter 23 or the wire width 23a of the head arches.
  • FIG. 2 shows that opposite winding legs 8 run below the supporting winding legs 7, which, in contrast to the contact surfaces 12, can have a round cross-section 9a or a triangular cross-section 9b.
  • the opposite winding legs 10 can also have rectangular cross sections 11.
  • FIG. 2 shows that the opposite winding legs 10 can also have a rectangular cross section 11.
  • the wire from which the coils 3 or 4 are made is an elastic plastic or metal wire 5, the diameter 6 of which in some exemplary embodiments of the invention is approximately the same as the diameter of the head arches 17.
  • the opposite winding legs 10 can also have flat contact surfaces 12 in particular exemplary embodiments of the invention.
  • the flat contact surfaces 12 have a width 13 and edges 14, between which distances 16 are arranged.
  • the flat structure consists of left-hand and right-hand helixes 4 and 3. It can be seen that the head arches of adjacent helixes are fundamentally not in contact with one another as a result of a spiral spring-like tension. This is due to the fact that the coils 2, 3, 4 are wound on division and that they have a tension spring-like pre-tension such that the fixed space 18 between their head bends 17 is larger than their wire diameter 23 or their wire width 23a.
  • the wires 22 of the head arches 17 (FIG.
  • the width 13 of the flat contact surfaces can be up to twice as large as the wire diameter 23 or the wire width 23a of the head bends 17.
  • the width 13 of the flat contact surfaces 12 and the winding legs 7, 10 having them is twice as large as or larger than the wire diameter 23 or the wire width 23a of the head bends 17. Which width ratio is selected in detail depends on the intended use of the fabric.
  • FIG. 3 shows an embodiment in which the coils 2 are all left-handed coils 4.
  • FIG. 4 shows an exemplary embodiment in which all the coils 2 are right-handed coils 3.
  • the exemplary embodiment according to FIG. 4 shows that the edges 14 of adjacent flat contact surfaces 12 lie close together. According to the embodiment shown in Figure 3, a distance 16 is provided between the edges 14.
  • the configuration of the width 13 of the flat bearing surfaces 12 and the resulting spacing 16 between the flat bearing surfaces 12 allow, for example, in paper production airflow passing through the fabrics varies.
  • Figure 5 shows an embodiment in which the winding legs 7 and the opposite winding legs 8 and 10, not shown, with the plug wires 25 form an angle a different from 90 °, while the head arches 17 of the spirals 2, 3, 4 form an angle ⁇ of approximately Take 90 °.
  • This design of the flat structure allows the passage area for the air to be provided with an even smaller cross section than in the other exemplary embodiments.
  • FIGS. 6 and 7 show dimensions of the individual helices in detail.
  • FIG. 6 shows that the load-bearing winding legs 7 have an almost rectangular cross-section 11, as a result of which flat contact surfaces 12 are created.
  • the width 13 of these load-bearing winding legs 7 is dimensioned in accordance with FIG. 6 such that a distance is maintained between the edges 14. This distance is fixed.
  • the opposite winding legs 8 have a round cross section 20 according to FIG.
  • the load-bearing turn legs 7 and the opposite turn legs 10 both have rectangular cross sections 11.
  • the head arches 17, on the other hand, have a squeezed cross-section 21, which may also have resulted from an oval, triangular or rectangular base cross-section 20a, 20b, 20c.
  • the schematic representation according to FIG. 8 reveals details of the mass once again.
  • the head arches 17 have outer edges 19.
  • the total distance between these outer edges 19 is designated 32. It is given by the double wire diameter 23 or the double wire width 23a of the head bends 17, the diameter 26 of the plug wire 25 and by the play 27 between the head bends 17 and the plug wire 25. As a result of this play, the hinge effect between adjacent coils is possible.
  • FIG. 8 in FIG. 8 denotes the so-called overlap area, which is given by the diameter 26 of the plug wire 25 and by the play 27 between the plug wire 25 and the head arches 17. With 33 the distance from the inner edge of a head bow to the outer edge 19 of the opposite one Called head bow.
  • FIGS. 9 and 10 show further details of the fabric with cross sections 11 of the head arches 17, which are rectangular, and cross sections 9a and 9b, which are oval or triangular. Which wire or head bow cross-section is used in detail depends on the desired use of the fabric.
  • the head arches 17 are somewhat crushed during the manufacture of the coils. As a result of subsequent fixing of the coils, in most exemplary embodiments they have the oval shape according to FIG. 10.
  • FIG. 1 reveals special features of an embodiment.
  • the edge fastenings 28 are necessary in order to permanently fix the width of the flat structures. Eyelets 29 and spikes 30 are indicated on the right side of FIG. 1, whereas reinforcements 31 can be arranged in the edge fastenings 28 on the left side of FIG.
  • the flat structures can be pulled apart as required, especially if the plug wires 25 are made of metal, as a result of which the passage of air through the flat structure can be varied as desired.
  • barbs 34 are provided.
  • the tabs 35 into which mandrels can also be inserted for pulling the flat structures apart during operation, have securing holes 36 which ensure their secure fit within the edge fastenings 28 made of plastic.
