Definitions
- the invention relates to a porous paper machine clothing for dewatering a paper web in a paper machine, in particular as a paper machine felt or Trokkensieb, with a scrim from at least one layer Longitudinal threads and at least one layer crossing the longitudinal threads Cross threads.
- Porous paper machine clothing is long and wide Ribbons in different lots of a paper machine revolve and on which the paper web through the paper machine is transported.
- Sheet forming section becomes a fiber pulp on the paper machine clothing applied, wherein a fibrous web forms. This is covered by the paper machine clothing drained through.
- the paper machine clothing consists of a textile thread formation that is so porous is that coming from the fibrous web liquid as a result of gravitational and negative pressure imprinting the paper machine clothing is discharged through.
- the subsequent press section are paper web and papermachine clothing passed through roller presses, so that the still in the paper web Liquid through the paper machine clothing through is squeezed out.
- the papermachine clothing is as a felt with a carrier of a textile thread formation educated.
- drying section become paper web and paper machine clothing over heated rollers led, thereby further draining - in this case, one speaks better of drying - he follows.
- threadline paper machine clothing i.e. Dryer fabrics used, which are also porous, to remove the vapor through the pores.
- the textile thread structures are primarily as tissue educated.
- scrim known in which the threads are not interconnected, so not interwoven or meshed are.
- US-A-3,097,413 is such a paper machine clothing disclosed. She has a scrim from one Location longitudinal threads that are parallel and spaced apart are lost and not connected. On The layer is a non-woven fabric applied to the longitudinal threads includes and is needled with these.
- the invention is based on the object, a paper machine clothing with a scrim, that with him regardless of the type of threads a high Dimensional stability is achievable and that it is for everyone Part of a paper machine is suitable.
- a second The object is a method for its production provide.
- the first object is achieved according to the invention that the longitudinal and transverse threads at crossing points over a Adhesive are glued together.
- adhesives come in particular hot melt adhesive whose melting temperature below the threads lies, diffusion adhesive, contact adhesive and / or reaction adhesive in question.
- the possibility is opened, a direct connection between the longitudinal and transverse threads at the crossing points regardless of the material of the threads to effect. So you do not have to rely on bicomponent threads anymore, although the basic idea of the invention is also such Includes threads, but can Einkomponentenfäden directly connect with each other.
- Paper machine clothing has the advantage of high flexibility in terms of the number of layers, the thread density and the Choice of material. Besides, are for the production no elaborate textile machines, such as weaving and knitting machines, required, in addition to the width of them limited paper machine clothing to be produced. A such limitation does not exist with thread plies, i. they can be made in virtually any width become. In addition, can be at Fadengelegen on the tissue necessary thermofixing be dispensed with, if the threads previously sufficiently thermally treated.
- the Longitudinal and transverse threads at intersections additionally form-fitting connected to each other, the connection each from a recess in the one thread and a protrusion at the intersecting bordering it Thread or off at the intersection points aligned recesses and these passing pins, e.g. Bolts or rivets made of plastic or metal can.
- Such a positive connection supports the adhesive bond and gives even more strength.
- the longitudinal and transverse threads as Form flat threads with rectangular cross section. On this way a surface contact is created at the crossing points, and the area over which the threads are connected are glued, is considerably enlarged and thus firmer.
- width for the longitudinal and transverse threads has a range of 2 to 20 mm, preferably 8 to 12 mm, proved.
- the thickness should be between 0.3 to 2 mm, preferably 0.6 to 1.2 mm, wherein the transverse threads should have at most the same thickness as the longitudinal threads.
- Permeability to ensure water or steam can through holes in the longitudinal and / or Cross threads may be provided.
- the permeability can be controlled arbitrarily, where there is also the possibility of permeability different across the width of the paper machine clothing to shape, e.g. in the middle higher than in the border areas or vice versa.
- the passage openings can be designed as round holes or elongated slots his.
- the paper machine clothing according to the invention can be a have any number of layers, each one alternating a layer with longitudinal threads and a layer with transverse threads, So each adjacent to each other.
- a expedient number are two or three layers, in the the former case prefers a lower longitudinal thread layer an upper Querfadengelege is combined and in the latter Case a layer with transverse threads on both sides of each one Location longitudinal threads is included. In this way At the top and bottom a longitudinal structure is formed. Of course, there is the possibility, vice versa procedure, so that at the top and bottom by the there existing transverse threads is a transverse structure.
- the permeability or permeability of the paper machine clothing can also be, for example, by the Width dimensions of the longitudinal and / or transverse threads and / or adjust their thread density within wide limits. It exists also the possibility in at least one position the To arrange longitudinal threads so that they are in the middle area have a different thread density than in the border areas, especially in the middle range a lower than in the edge areas.
- the thread scrim according to the invention can also be in a simple way eyelets on the front sides of the paper machine clothing by turning over longitudinal threads below Forming loops to make with them one To form plug wire seam.
- This can be done in the way that end pieces of longitudinal threads to a first layer the front sides of the paper machine clothing under education of loops on the side facing away from this situation the situation turned over with transverse threads and at several of these Transverse threads, preferably on at least five transverse threads, be attached.
- the attachment can also on the Longitudinal threads themselves are made.
- the fixation can in both cases form-fitting, e.g. by means of bolts or Rivets made of plastic or metal.
- the loop formation should expediently only with one Part of the longitudinal threads happen so the two End edges with their loops comb-like grab and so a passageway for a pintle can form.
- the permeability is not worsened in this area, should be at the ends of the end pieces longitudinal threads off the situation with transverse threads adjacent second layer with Connecting longitudinal threads, i. these longitudinal threads abut dull on the end pieces, so do not overlap with them, so that there is no compression in this area comes from longitudinal threads.
- the threads can be reinforced, e.g. fiber reinforced with glass fibers, carbon fibers and / or Be ceramic fibers, the fibers also as short cut fibers may be present.
- the paper machine clothing according to the invention can be use in all lots of a paper machine and due its flexibility to the respective requirements in optimally adapt to these games.
- the paper machine clothing from the scrim, which does not exclude, that the scrim is combined with other components is, for example, a nonwoven fabric.
- the thread scrim according to the invention to use as a carrier and with a fiber layer oror be provided on both sides, for example by oror double-sided needling or laminating of fiber webs or spunbonded nonwovens.
- the longitudinal and transverse threads at intersection points form fit connected to each other, e.g. by interlocking each of a projection on the a thread and a complementary recess on the crossing thread or by inserting a pin like a bolt or a rivet, in alignment with each other Recesses in the threads. This will be the connection reinforced at the crossroads.
- the production of the yarn layer in the Made way that initially longitudinal threads parallel to each other be spanned, for example, between two parallel Thread trees, and then on these longitudinal threads one after the other individually or in groups laid cross threads and at the crossing points longitudinal and transverse threads with each other be glued, with an additional form-fitting Connection can be made by connecting bolts in holes aligned at the crossing points be kicked or a projection on the one Thread in a complementary recess in the other thread is pressed.
- a felt for example the use in the press section of a paper machine, should on the scrim one or both sides of a fiber layer applied and attached to this.
- the attachment can be by needling, gluing or melting happen.
- transverse threads are not perpendicular to must pass the longitudinal threads, but that with the inventive Method also produce scrim are where the transverse threads are oblique to the longitudinal threads run. It can also be two layers of transverse threads be provided, in which the transverse threads of a layer the longitudinal threads cross at a different angle than the the other location.
- the papermachine fabric shown in Figures 1 to 4 1 consists of a Fadengelege whose lower Layer 2 of longitudinal threads - exemplified by 3 - is formed.
- the longitudinal threads 3 have - as in particular From Figure 3 can be seen - rectangular cross-section and equal distance from each other. For the manufacturing process they are - what is not visible here - with theirs left ends wound on a thread tree. On the right is - not visible here - a second tree provided on the finished paper machine clothing 1 is wound up. In this direction (Arrow A) moves the paper machine clothing 1.
- the transverse threads 5 have a wide Distance - it essentially corresponds to the distance the longitudinal threads 3 -, the transverse threads 6 a close distance in order to reduce the permeability of the paper machine clothing 1 and the transverse threads 7 also a tight Distance, but a much smaller width than the Cross threads 5, 6. It is understood that these differences in an actual paper machine clothing not are present, i. the same transverse threads come along equal distance from each other for use. Through the presentation should only be symbolized that the invention Process various types of longitudinal and Cross threads 3, 5, 6, 7 and thread densities possible. The same applies to the longitudinal threads 3, in which case in addition still given the opportunity, their distances vary across the width, e.g. in the middle area to provide a lower yarn density than in the two Border areas or vice versa.
- the longitudinal threads 3 spanned between the two trees and then the transverse threads 5, 6, 7 over the longitudinal threads 3 laid. This can be done by machine, for example, with a Transverse panel device happen, as they in principle US-A-3,097,413 is known.
- Cross threads 5, 6, 7 with the longitudinal threads 3 they are at the Intersection points - exemplified by 8 - via an adhesive layer - designated 10 by way of example - glued together.
- the glue application can on the longitudinal and / or transverse threads 3, 5, 6, 7 pointwise or area by area, with the adhesive in the latter Case should be subsequently removed, for example using a solvent based on the finished paper machine is applied.
- a plate e.g. a Glass plate
- the transverse threads 5, 6, 7 on the longitudinal threads 3 presses and thus prevents a shift between the two until the adhesive bond has become firm.
- Figures 5 and 6 show sections of another paper machine clothing 11 with a lower layer 12 Longitudinal threads - exemplified with 13 - and one upper layer 14 of transverse threads - designated by way of example with 15. It is understood that a plurality of longitudinal threads 13 are present and that the transverse threads 15 over the entire width of the paper machine clothing 11 extends.
- Longitudinal and transverse threads 13, 15 have here also rechtkkigen Cross-section, wherein the transverse threads 15 are flatter as the longitudinal threads 13.
- the longitudinal and transverse threads 13, 15 positively connected with each other, namely via connecting bolts - designated 17 by way of example -, each with aligned holes - by way of example denoted by 18, 19 - in the longitudinal and transverse threads 13, 15 prevail.
- the connecting bolts 17 also on the longitudinal threads 13 or the Cross threads 15 be formed so that only the other Threads have holes in which then the connecting bolts 17 are pushed into it.
- the positive connection serves for additional fixation the longitudinal and transverse threads 13, 15 at the crossing points 16 and supports the connection by means of adhesive layers - designated 20 by way of example -.
