Description
457 541 2 material. Underlagstyget, som kan besta av ett enda skikt eller flera skikt, är tillräckligt glest för att möjliggöra fullständig impregnering av materialet, sa att eventuella mellanrum i tyget elimineras. En viktig fördel med denna bandkonstruktion bestar i att det kan tillverkas i vilken som helst längd, eftersom det icke kräver en dorn under tillverkningen av detsamma. Under- lagstyget göres ändlöst enligt kända metoder och belägges och impregneras sedan fullständigt med det polymera materialet. 457 541 2 material. The backing fabric, which may consist of a single layer or several layers, is sufficiently sparse to enable complete impregnation of the material, so that any gaps in the fabric are eliminated. An important advantage of this belt construction is that it can be manufactured in any length, since it does not require a mandrel during the manufacture of the same. The backing fabric is made endless according to known methods and is then coated and impregnated completely with the polymeric material.
Det resulterande bandet är bade lätt och tillräckligt stabilt för att kunna användas i en pappersmaskin. Det har tillräcklig nötningshâllfasthet för att kunna motstå den nötning som kan ske i griporganet. Till skillnad fran material, som är uppbyggda pa liknande sätt som en gummiring och kan flyta och/eller sönderdelas åstadkommas genom uppfinningen ett band, bibehåller sin sammanhållning. som Detta band löser även problemet med utbuktning nära griporganet. Bandet har en likformigt mjuk yta av polymert material, mot vilken en trycksko ligger an och utövar tryck i riktning mot valsen.The resulting belt is both light and stable enough to be used in a paper machine. It has sufficient abrasion resistance to withstand the abrasion that can occur in the gripping member. Unlike materials which are constructed in a manner similar to a rubber ring and which can float and / or disintegrate, a belt is provided by the invention which retains its cohesion. as This band also solves the problem of bulging near the gripping means. The belt has a uniformly soft surface of polymeric material, against which a pressure shoe abuts and exerts pressure in the direction of the roller.
Uppfinningen skall i det följande närmare beskrivas med hänvisning till bifogade ritning.The invention will be described in more detail below with reference to the accompanying drawing.
F ig. 1 visar i sídvy ett làngsträckt griporgan enligt uppfinningen.F ig. 1 shows in side view an elongate gripping member according to the invention.
F ig. 2 visar delvis i sektion och sett framifrån griporganet enligt fig. l.F ig. 2 shows partly in section and seen from the front the gripping member according to fig.
F ig. 3 visar i längdsektion bandet som användes vid uppfinningen.F ig. 3 shows in longitudinal section the strap used in the invention.
Det langsträckta press- och griporganet enligt uppfinningen för att avvattna en framförd vävnad innefattar griporganet 10, som bildas av en cylindrisk pressvals 12, en trycksko 14 som har en konkav yta vettande mot pressvalsen, och ett band 16 anordnat sa att det ligger an *mot pressvalsens yta. Den konkava ytan pa tryckskon har omkring samma krökningsradie som pressvalsen. Avståndet mellan pressvalsen och tryckskon kan regleras medelst kända hydrauliska eller mekaniska anordningar (icke visade), till en stång 18, vilken är ledbart fästad vid skon 14. krökt för att utöva det önskade trycket pa skon. som ovan beskrivits och visats i fig. som är anslutna Stângen kan även vara Tryckskon och pressvalsen, l-2, är av konventionellt utförande och andra anordningar kan användas i enlighet med uppfinningen.The elongate pressing and gripping means according to the invention for dewatering a advanced tissue comprises the gripping means 10, which is formed by a cylindrical press roll 12, a pressure shoe 14 having a concave surface facing the press roll, and a belt 16 arranged so as to abut the surface of the press roll. The concave surface of the pressure shoe has approximately the same radius of curvature as the press roll. The distance between the press roll and the pressure shoe can be controlled by means of known hydraulic or mechanical devices (not shown), to a rod 18, which is articulated attached to the shoe 14. curved to exert the desired pressure on the shoe. as described above and shown in Figs. Connected The rod may also be the pressure shoe and the press roll, 1-2, is of conventional design and other devices may be used in accordance with the invention.
Bandet 16, som användes enligt uppfinningen, visas i detalj i fig. 3. Det har visat sig vara överlägset i jämförelse med tidigare kända band bade med avseende på användning och tillverkning. Bandet 16 innefattar ett underlagstyg 20, som är fullständigt impregnerat med ett polymert material 22. Värmehärdande hartser sasom polyuretaner har visat sig vara lämpliga impregneringsmaterial. Termoplastiska polymerer såsom polypropen är även användbara. 457 541 3 Underlagstyget 20 är tillräckligt glest för att möjliggöra fullständig impregnering. Detta eliminerar möjligheten att mellanrum bildas i det slutliga tyget, vilka mellanrum skulle möjliggöra att smörjmedel, som användes mellan bandet och skon, passerar genom bandet och förorenar filten och den fibrösa vävnaden. Det är utfört ändlöst i sin slutliga form och likformigt i tjocklek. Bandet maste även utföras sa ' det far tillräcklig stabilitet vid användning i en pappersrnaskin. Det maste sålunda ha längdstabilitet, breddstabilitet och styrbarhet.The belt 16 used according to the invention is shown in detail in Fig. 3. It has been found to be superior to prior art belts both in terms of use and manufacture. The belt 16 comprises a backing fabric 20 which is completely impregnated with a polymeric material 22. Thermosetting resins such as polyurethanes have been found to be suitable impregnating materials. Thermoplastic polymers such as polypropylene are also useful. 457 541 3 The backing fabric 20 is sufficiently sparse to enable complete impregnation. This eliminates the possibility of gaps forming in the final fabric, which gaps would allow lubricant used between the belt and the shoe to pass through the belt and contaminate the felt and fibrous tissue. It is made endlessly in its final shape and uniform in thickness. The belt must also be made so that it has sufficient stability when used in a paper machine. It must thus have longitudinal stability, width stability and steerability.
Den använda termoplastiska hartsen eller värmehärdande hartsen bör ha en hundraprocentig fast sammansättning, sa att bubblor icke kan bildas under härdningen av hartsen i bandet.The thermoplastic resin used or the thermosetting resin should have a 100% solid composition, so that bubbles cannot form during the curing of the resin in the strip.
Bandet har minst en slät sida l6', som gör kontakt med tryckskon 14.The belt has at least one smooth side 16 ', which makes contact with the pressure shoe 14.
Band tillverkade enligt uppfinningen har befunnits ha manga önskvärda egenskaper. De förflyttas lätt över tryckskon och kan överföra tryck fran skon till vävnaden och pressvalsen. Tillräcklig böjlighet erhalles, och banden har visat sig vara opåverkade av Smörjmedel, som paföres före inträdet i griporganet. l jämförelse med kända band åstadkommer uppfinningen ett _band som är relativt tunt och lätt. Tjocka band har den nackdelen att de tenderar att flyta medan de befinner sig i griporganet. Ett band med dimensionerna 750 x 430 cm impregnerat med en värmehärdande harts i enlighet med uppfinningen väger omkring 90 kg. Ett band av liknande storlek, som har egenskapen att motsta utbuktning och har en struktur enligt de ovannämnda patenten, väger omkring 550 kg. Till skillnad fran tyngre band kräver bandet enligt uppfinningen icke nagon armering.Bands made according to the invention have been found to have many desirable properties. They move easily over the pressure shoe and can transfer pressure from the shoe to the tissue and the press roll. Sufficient flexibility is obtained, and the straps have been found to be unaffected by Lubricant, which is applied before entering the gripping member. In comparison with known belts, the invention provides a belt which is relatively thin and light. Thick bands have the disadvantage that they tend to float while in the gripping means. A strip with the dimensions 750 x 430 cm impregnated with a thermosetting resin in accordance with the invention weighs about 90 kg. A belt of similar size, which has the property of resisting bulging and has a structure according to the above-mentioned patents, weighs about 550 kg. Unlike heavier belts, the belt according to the invention does not require any reinforcement.
I Tillverkningen av bandet enligt uppfinningen kan utföras ekonomiskt och utan behov av dornar eller autoklaver, vilket begränsar storleken av andra band. Följaktligen kan ett band av godtycklig längd framställas. Underlaget väves först. En väv kan införas i underlaget om sa önskas. Om underlaget icke har vävts ändlöst, göres det därpa ändlöst med användning av konventionell teknik, som användes för att bilda vävar i pappersindustrin. Ett polymert material paföres sedan underlagsväven och bildar en sammanhängande del därav. Hartsen far härdas under en tillräcklig tid. Efter härdningen kan hartsytan blästras eller slipas sa att ett band av likformig tjocklek och minst en slät yta bildas.The manufacture of the belt according to the invention can be carried out economically and without the need for mandrels or autoclaves, which limits the size of other belts. Consequently, a band of any length can be produced. The substrate is woven first. A fabric can be inserted into the substrate if desired. If the substrate has not been woven endlessly, it is made endlessly using conventional techniques used to form fabrics in the paper industry. A polymeric material is then applied to the backing fabric to form a continuous portion thereof. The resin must be cured for a sufficient time. After curing, the resin surface can be blasted or ground so that a strip of uniform thickness and at least one smooth surface is formed.
Ett band utfört enligt uppfinningen kan användas tillsammans med apparaten, som visas i fig. 1. Bandet 16 är beläget mellan tryckskon och 457 541 4 pressvalsen. Den släta, belagda sidan 16' av bandet ligger an mot skon. En fibrös vävnad 24 föres mellan en första och en andra filt 26 respektive 27 och införas i griporganet 10. .Den sida av bandet 16, som ligger an mot skon 14, smörjes medelst en smörjanordning 28 belägen framför griporganet.A belt made according to the invention can be used together with the apparatus shown in Fig. 1. The belt 16 is located between the pressure shoe and the press roll. The smooth, coated side 16 'of the strap abuts the shoe. A fibrous web 24 is passed between a first and a second felt 26 and 27, respectively, and inserted into the gripping means 10. The side of the band 16, which abuts the shoe 14, is lubricated by means of a lubricating device 28 located in front of the gripping means.
Bandet 16 repareras lätt, om ett hal eller annat ytfel skulle uppsta därpa. Den skadade delen rengöres med ett lösningsmedel och en lämplig mängd avi beläggningsmaterial tillföras med ett knivblad. En värmekanon användes för att härda ytan, vilken därpa kan blästras.The belt 16 is easily repaired if a slip or other surface defect should occur thereon. The damaged part is cleaned with a solvent and a suitable amount of coating material is applied with a knife blade. A heat gun is used to cure the surface, which can then be blasted.
Pa grund av de utmärkta böjningsegenskaperna hos underlaget och att beläggningen kan hallas vid ett minimum, kommer bandets yta att ha mindre tendens att spricka pa grund av böjningsutmattning. Detta beror pa att till följd av den ringa tjockleken beläggningens ytplan befinner sig pa ett minimalt avstand fran böjningens neutrallager. Detta minskar förlängningen och sammantryckningen vid ytplanet under höjningen.Due to the excellent bending properties of the substrate and the fact that the coating can be kept to a minimum, the surface of the strip will have less tendency to crack due to bending fatigue. This is because, due to the small thickness, the surface plane of the coating is at a minimal distance from the neutral layer of the bend. This reduces the elongation and compression at the surface plane during the elevation.
Exempel l Ett i tva skikt utfört enkeltradigt underlagstyg flatvävdes, värmestabiliserades och gjordes ändlöst pa känt sätt. Tyget belades sedan med en hundraprocentig fast polyuretanharts och härdades. Beläggningen kan utföras med användning av en avstrykningskniv e.dyl. för att en slät yta skall erhallas. Om utsidan av underlagstyget belägges, kan det vändas ut och in för användning.Example 1 A single-layer single-ply backing fabric was flattened, heat-stabilized and made endless in a known manner. The fabric was then coated with a 100% solid polyurethane resin and cured. The coating can be performed using a wiping knife and the like. in order to obtain a smooth surface. If the outside of the backing fabric is coated, it can be turned inside out for use.
Exempel 2 Ett enkeltradigt tyg väves i tva skikt med tillräcklig gleshet. Det värmehärdas och göres ândlöst. Det ändlösa tyget placeras i en ytbehandlingsanordning innefattande ett par valsar.Example 2 A single-ply fabric is woven in two layers with sufficient sparseness. It is heat cured and made breathless. The endless fabric is placed in a surface treatment device comprising a pair of rollers.
Den ena av valsarna är. en med olja uppvärmd cylinder.One of the rollers is. an oil-heated cylinder.
Ett blad av polyuretan med lämplig likformig tjocklek placeras pa insidan av tyget och far passera mellan de n uppvärmda cylindern och själva väven.A sheet of polyurethane of suitable uniform thickness is placed on the inside of the fabric and allowed to pass between the n heated cylinder and the fabric itself.
Den uppvärmda cylinderns temperatur halles i huvudsak konstant sa att den plastlska filmen smältes likformigt. Bladet justeras sa att det icke förekommer nagon överlappning i materialet som skall pressas i väven. När väven och bladet passerar runt den uppvärmda cylindern, upprätthalles tillräcklig värme för att polyuretanet skall flyta in i väven. En pressvals kan användas mot vävens utsida för att säkerställa fullständig impregnering. Polyuretanet göres plastiskt och pressas in i vävens mellanrum.The temperature of the heated cylinder is kept substantially constant so that the plastic film melts uniformly. The blade is adjusted so that there is no overlap in the material to be pressed into the fabric. As the fabric and blade pass around the heated cylinder, sufficient heat is maintained for the polyurethane to flow into the fabric. A press roll can be used against the outside of the fabric to ensure complete impregnation. The polyurethane is made of plastic and pressed into the space between the fabric.
En slät yta erhalles, vilket icke kräver nagra ytterligare ytbehandlingssteg.A smooth surface is obtained, which does not require any additional surface treatment steps.
Användningen av ett till 100% polymert blad eliminerar även eventuella problem, som kan uppsta i den färdiga väven till följd av att man använder ett impregneringsmedel- innehallande lösningsmedel eller vatten. Efter det väven 457 541 5 har underkastats pressningen, justeras och tätas kanterna för drift i en pappersmaskin.The use of a 100% polymeric sheet also eliminates any problems that may arise in the finished fabric as a result of using an impregnating agent-containing solvent or water. After the fabric 457 541 has been subjected to the pressing, the edges are adjusted and sealed for operation in a paper machine.
Exemgel 3 Man framtager ett enkeltradigt tyg pa polyester-bas med tillräcklig gleshet för impregnering. Väven är utförd i tvâ skikt med både bredd- och längdstabilitet. En film av polypropen med en tjocklek av omkring 0,5 mm eller mera sammansmältes med underlagstyget pa det sätt som beskrivits i exempel 2. Den uppvärmda cylinderns temperatur hàlles konstant så att den plastiska filmen smältes likformigt. Underlagstyget har en högre smälttemperatur än polypropenfílmen och påverkas icke av uppvärmningen.Example gel 3 A single-line polyester-based fabric is produced with sufficient sparseness for impregnation. The fabric is made in two layers with both width and length stability. A polypropylene film having a thickness of about 0.5 mm or more is fused to the backing fabric in the manner described in Example 2. The temperature of the heated cylinder is kept constant so that the plastic film melts uniformly. The backing fabric has a higher melting temperature than the polypropylene film and is not affected by the heating.
Sedan tyget har underkastats pressningen, justeras och tätas kanterna för drift i en pappersrnaskin.After the fabric has been subjected to the pressing, the edges are adjusted and sealed for operation in a paper machine.
Såsom lätt inses kan bandet, som användes vid uppfinningen, innefatta ett underlagstyg utfört av olika polymera material, som har de nödvändiga egenskaperna för användning i pappersmaskiner. Andra material än polyuretan och polypropen kan även användas som beläggningsmaterial.As will be readily appreciated, the belt used in the invention may comprise a backing fabric made of various polymeric materials which have the necessary properties for use in paper machines. Materials other than polyurethane and polypropylene can also be used as coating materials.
