Definitions

  • the invention relates to a belt for use in paper machines, in particular in wet presses with an extended press nip, which has a flexible, liquid-impermeable belt layer which is smooth on the back and in the front of which there is a carrier web which has cavities, for example a fabric, knitted fabric or a wire link belt is partially embedded, with longitudinal threads extending in the band layer in the running direction of the band.
  • wet presses with an extended press nip so-called “shoe presses” have been developed in which the paper web is exposed to high press pressure over a longer distance and thus for a correspondingly longer time, so that it runs out of the wet press with a higher dry content.
  • Extended press naps are used in particular for tapes that have a flexible, liquid-impermeable tape layer that is smooth on the back. With this smooth back, they run in the press nip over a pressure shoe that is hydraulically actuated and presses the belt in the direction of an opposite pressure roller.
  • the paper web to be dewatered is passed between this pressure roller and the belt, with the paper web being accompanied on at least one side by a co-operating wet felt which removes the squeezed water.
  • the front is structured.
  • tapes were developed, on the front of which carrier webs were only partially embedded, that is to say partially protruding from the tape layer. In this way, cavities and channels for water drainage were created.
  • Multi-layer fabrics (DE-PS 32 35 468, EP-PS 0 098 502; EP-OS 0 138 797; DE-GM 83 19 684.6; EP-OS 0 185 108) have been proposed as carrier webs.
  • wire link belts EP-PS 0 098 502 or warp-knitted fabrics (EP OS 0 290 653) were also possible.
  • Wire link belt as a carrier web has also been proposed to allow the coupled wire coils to run in the longitudinal direction and to additionally insert multi and / or monofilaments into these wire coils to absorb the longitudinal forces (EP-PS 0 098 502). They should be embedded in the strip layer in order to improve the stability of the strip and also the retention of the wire coils in the strip layer.
  • the carrier web only slightly, i. H. not deeper than half the thickness of the strip layer, to be stored in it (EP-PS 0 098 502).
  • These longitudinal threads also do not prevent the formation of a flex wave in the direction of travel in front of the pressure shoe and, moreover, can only absorb tensile forces to a limited extent, since they are in any case in an area which is relieved of tensile forces by the carrier web. It is therefore necessary to use a relatively hard material for the band layer so that the aforementioned flex wave does not occur. This in turn has the consequence that the band is relatively stiff and therefore only incompletely adapts to the shape of the pressure shoe.
  • the invention has for its object to form a tape of the type mentioned so that it can withstand large tensile and flexural stresses on the one hand, but on the other hand high flexibility and thus adaptability to the circumstances, especially in Press nip.
  • the carrier web is adhered to admit the carrier web only in a partial cross-section of the band layer in order to provide a sufficient drainage volume on the front side of the band layer with a relatively simply constructed carrier web and not to stiffen the band excessively by the carrier web.
  • This embodiment is combined with the arrangement of additional longitudinal threads which do not run through the carrier web, as in the prior art, but instead extend outside the carrier web into the region which is not occupied by the carrier web. Since the ends of the longitudinal threads are also connected to one another with tensile strength - be it directly or with interposed tensile elements - they can absorb high tensile forces. In this way, the strip layer is strengthened and stabilized where it was previously most at risk with the generic strips.
  • the strip layer is given an elongation behavior which is uniform over the cross section and which is determined on the one hand by the carrier web and on the other hand by the longitudinal threads.
  • This largely prevents the occurrence of whale waves and also opens up the possibility of using comparatively soft material for the strip layer.
  • This is what makes the tape special adaptable, especially since the longitudinal threads practically do not affect the flexibility of the tape because they have no spatial expansion in the thickness direction.
  • the longitudinal threads can consist of a material whose tensile strength is greater than that of the material from which parts of the carrier web that are subjected to tension are made. Materials can therefore be used for the carrier web which are not optimized with regard to their tensile strength, but are better adapted to the requirements of the carrier web.
  • at least the parts forming the outer plane of the carrier web can consist of a material that is more wear-resistant than the material of the longitudinal threads. The carrier web can therefore be designed to be highly wear-resistant.
  • the longitudinal threads are formed by one or more continuous individual threads, which due to their incline in the transverse direction do not extend exactly in the running direction. Nevertheless, the same advantages as in the embodiment with single threads extending in the running direction are achieved.
  • the advantages of the longitudinal threads arranged according to the invention are not impaired by the fact that the longitudinal threads are connected and / or integrated at regular intervals with the carrier web. Rather, this achieves the additional advantage that the carrier web has a better hold in the strip layer, ie does not tend to tear out of the strip layer.
  • the longitudinal threads thus have an additional function.
  • At least one additional thread is let into the band layer, which extends in a zigzag shape progressively over the running direction of the band.
  • This additional thread advances in the running direction over the entire length of the band, but not straight, but zigzag-shaped, so that its individual thread sections between the reversal points extend essentially transversely to the running direction of the band.
  • This will get that Band in the transverse direction a higher resistance, in particular an improved strength against tensile and flexing stress in this direction.
  • Such stresses occur particularly at the lateral boundaries of the pressure shoe and can lead to bulging of the band in the two edge areas.
  • the additional thread - several such additional threads can also be provided - is guided in such a way that thread sections which run outside the carrier web alternate with thread sections which are integrated in the carrier web. In this way, a high tear-out strength of the carrier web is additionally achieved without it having to be inserted deep into the strip layer.
  • the additional thread or at least one of the additional threads has a helical course with a reversal of direction between two thread sections. This means that a thread section runs outside the carrier web and, after a reversal of direction, passes through the carrier web and comes to lie outside the carrier web again after another reversal of direction. It is also expedient for the additional thread or at least one of the additional threads to extend between the edges of the band. However, it should be ensured that the additional thread in question does not protrude beyond the edge of the carrier web, but rather that the direction is reversed within the lateral boundaries of the carrier web.
  • fabrics in particular multi-layer fabrics, knitted fabrics come as the carrier web and especially wire link belts in question.
  • wire link belts which are composed of wire helices which extend transversely to the direction of travel of the belt, since they can be easily connected at the seam with the help of a coupling wire when the belt is finally formed.
  • the additional thread or the additional threads each run or run with one thread section through a wire coil and with the following thread section after a reversal of direction over the next wire coil.
  • the longitudinal threads extend between the carrier web and the thread sections of the additional thread or at least one additional thread running outside the carrier web.
  • the longitudinal threads contribute to improving the tear-out strength of the carrier web.
  • the longitudinal threads can be connected with the additional thread or at least one of the additional threads at intersection points.
  • the longitudinal threads are formed from individual threads, they can be knotted, welded, twisted or the like at their ends so that a tensile connection is produced.
  • the band can be seamless if the paper machine for which the band is intended permits the assembly of the closed band. In most cases, however, assembly is at least facilitated if the tape is designed so that it has a transverse seam at which the tape layer is interrupted and the carrier web is separable.
  • Such a separability of the carrier web can be produced in the case of woven and knitted fabrics by providing, for example, a plug-in wire seam, as is known in the case of dryer fabrics for paper machines.
  • Wire link belts with wire helixes extending transversely to the direction of travel can be separated practically at any point, provided that the wire helices are coupled to one another via coupling wires.
  • the carrier web can then be separated by removing the plug wire or coupling wire, so that the tape can be drawn into the paper machine comfortably.
  • the gap in the tape layer is closed by means of an adhesive, so that the tape layer is also impermeable to liquids in the area of the transverse seam.
  • the ends of the longitudinal threads can be releasably connected to one another in the area of the transverse seam, for example by virtue of the fact that they form overlapping loops through which at least one plug wire extends.
  • a plug-in seam connection is therefore also provided for the longitudinal threads.
  • a further possibility is to fasten the ends of the longitudinal threads in the region of the transverse seam to plug wires running transversely through the carrier web and arranged at a distance from one another.
  • the ends the longitudinal threads on both sides of the transverse seam can also be permanently connected to the carrier web.
  • the tensile force is then transmitted in the seam region via the carrier web itself, so that it must be designed to be sufficiently tensile at least in this region.
  • this design has the advantage that the longitudinal threads do not have to be taken into account when loosening or closing the transverse seam, ie that a separate process for the production of the tensile connection of the ends of the longitudinal threads is not connected to it.
  • this can be achieved in that the longitudinal threads are wound around the plug wires and then continue to run into the strip layer until it is interrupted.
  • the parts of the carrier web that are subjected to longitudinal tension in the area between the fastenings of the longitudinal threads on the carrier web should consist of the same material as the longitudinal threads themselves.
  • the tape according to the invention can be produced in such a way that, after the carrier web has been produced, several longitudinal threads are placed in the circumferential direction on the side to be provided with the tape layer, or at least one single thread is or are wound helically before the tape layer is applied. After the band layer has been applied, the longitudinal threads run inside and outside the carrier web.
  • the production should take place in such a way that the longitudinal threads in the seam region from the area provided for the band layer to the side of the carrier web be brought out that the band layer is applied with the seam of the carrier web closed and that after the band layer has solidified, the seam of the carrier web is opened and the band layer is severed in the transverse seam direction.
  • the carrier web is protected in the area of the transverse seam from the penetration of the material of the tape layer, which is done, for example, by a corresponding protective layer to cover the carrier web or by filling the carrier web with a soluble, in particular water-soluble substance, such as polyvinyl alcohol can.
  • the longitudinal threads are connected to the carrier web on both sides of the transverse seam region before the tape layer is applied.
  • the tape (1) shown in Figure (1) has a tape layer (2) with the front (3) and back (4).
  • the back (4) is smoothed. When used as intended in the wet press of a paper machine with an extended press nip, this rear side (4) slides past the pressure shoe there in the press nip.
  • a wire link belt (5) serving as a carrier web is partially embedded in the front (3) of the belt layer (2).
  • Such wire link belts (5) are known in particular as drying belts in the dryer section of paper machines. They consist of a multiplicity of wire helices extending transversely to the running direction of the band (1) - denoted for example by (6) - which are arranged next to one another in the running direction and overlap with their head arches - denoted by example (7). In the area of the overlap of the head arches (7) they are connected to one another in an articulated manner with the aid of coupling wires extending over the width of the wire helices (6) - designated by way of example (8).
  • Your winding legs - designated by way of example with (9) - between two head bends (7) run essentially straight, so that there is an essentially flat support surface (10) on the free side of the wire link belt (5).
  • a wet felt cloth lies against this support surface (10).
  • the paper web to be dewatered is carried on the other side of the wet felt cloth.
  • longitudinal threads extend in the running direction (arrow A) - designated by way of example (12). It is a plurality of longitudinal threads (12) arranged next to one another in one plane, this plane being parallel to the plane of the rear side (4).
  • the longitudinal threads (12) span the entire band (1) and essentially serve to absorb tensile forces in the region of the band layer (2) which is not taken up by the wire link band (5). It goes without saying that longitudinal threads (12) can also run in several planes arranged one above the other.
  • FIG. (2) The embodiment of a band (1) shown in Figure (2) corresponds to that of Figure (1) with one exception, so that the same parts are provided with the same reference numerals and in this respect reference is also made to the preceding description.
  • the exception is that an additional thread (13) runs in the strip layer (2), alternately once with a thread stretch - designated by (14) for example - outside a wire coil (6), i.e. between the wire link strip (5) and the back ( 4), and once with a thread section - designated by way of example with (15) - within an adjacent wire helix (6).
  • FIG. (3) shows the wire link strip (5) before the strip layer (2) is applied, that is to say without it.
  • the additional thread (13) runs back and forth between the edges of the wire link belt (5) in a zigzag shape or, in this special case, even helically, once by a wire helix (6) and after a reversal of direction over the adjacent wire coil (6).
  • the reversal points - denoted by way of example (16) - of the additional thread (13) are selected such that the additional thread (13) exits or enters the wire helix (6) before the last turn of the latter.
  • Figures (2) and (3) also show that longitudinal threads (12) run between the wire link belt (5) and the thread sections (14) running outside the wire helices (6).

  • the longitudinal threads (12) are first formed by a single thread, which has been helically laid around the wire link belt (5) in the running direction (arrow A) before the application of the strip layer (2), so that the longitudinal threads (12) each have one revolution of the single thread form.
  • the longitudinal threads (12) do not run exactly in the running direction (arrow A), because of the single thread wound with a certain pitch.

An area is created which is freed from the wire link belt (5) and which can be milled off, so that there is space for the connection of the ends of the longitudinal threads (12).
