Description

Opfindelsen angår en fremgangsmåde til fremstilling af en presseeller klemmevalse, idet der på en stålkerne formes en kappe indeholdende uvævet fibermateriale, Sådanne valser kan for eksempel finde anvendelse i vridemaskiner til udpresning af væden fra vådt 5 tøj.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method of producing a press or clamping roller, forming a sheath containing a non-woven fiber material on a steel core. Such rollers may, for example, be used in twisting machines to extrude the wet from wet clothing.
Valselegemer til vridemaskiner og lignende apparater består sædvanligvis hovedsagelig af massivt gummi, idet valselegemet af gummi er fastgjort på en stålkeme. Valselegemer af massivt gummi kan kun tåle små 10 mekaniske belastninger, og der må regnes med et stort slid. Det er derfor også allerede blevet foreslået at fremstille valselegemer af uvævet fibermateriale, idet skiver af et sådant fibermateriale bliver trykket aksialt på stålkernen. Sådanne valser kan i reglen optage store mekaniske belastninger. Det er imidlertid en ulempe, at dette 15 valselegeme kun har en ringe elasticitet. Valselegemer, der både er beregnet til store mekaniske påvirkninger og også har en( f .eks. til fremstilling af uvævet fibermateriale ønsket elasticitet, er hidtil ukendte.Roller bodies for twisting machines and similar apparatus usually consist mainly of solid rubber, the rubber roller body being fixed to a steel core. Solid rubber roller bodies can withstand only 10 mechanical loads, and a large wear must be expected. Therefore, it has also already been proposed to make roll bodies of nonwoven fibrous material, with slices of such fibrous material being axially pressed onto the steel core. Such rollers can usually absorb large mechanical loads. However, it is a disadvantage that this roller body has only a slight elasticity. Rolling bodies, which are intended both for large mechanical stresses and also have a desired elasticity (e.g. to produce nonwoven fibrous material), are novel.
20 Fra østrigsk patentskrift nr. 12.553 kendes en transportvalse til tekstilbaner, hvor der på en stålkeme er anbragt et enkelt lag af en skruelinjeformet opviklet strimmel af vævet materiale. En sådan valse har hverken den elasticitet eller modstandsdygtighed, der er -påkrævet i forbindelse med presse- og klemme vals er.20 From Austrian patent specification No. 12,553, a transport roller is known for textile webs, where a single layer of a helical wound strip of woven material is arranged on a steel core. Such a roller has neither the elasticity nor the resistance required in connection with pressing and clamping rollers.

Ved opfindelsen søges tilvejebragt en fremgangsmåde til fremstilling af en presse- eller klemmevalse af den indledningsvis angivne art, der har den hidtil ikke opnåede kombination af mekanisk belastningsevne og høj elasticitet. Fremgangsmåden ifølge opfindelsen er 30 ejendommelig ved, at der på stålkemen skruelinjeformet op vikles flere lag af gummi- og/eller plastarmerede strimler af uvævet fibermateriale på en sådan måde, at strimlerne i til hinanden grænsende lag krydser hinanden, og at lagene forbindes med hinanden ved hjælp af gummi- og/eller plastarmeringen. Det har vist sig, at man ^ 35 ved denne kombination af gummi eller plast og uvævet fibermateriale har mulighed for at opnå den kombination af elasticitet og modstandsdygtighed for store mekaniske påvirkninger, der stilles krav om i forbindelse med presse- eller klemmevalser.The invention seeks to provide a method for producing a press or clamping roll of the type mentioned initially, which has the hitherto not achieved combination of mechanical load capacity and high elasticity. The method according to the invention is characterized in that several coats of rubber and / or plastic reinforced strips of nonwoven fibrous material are wound on the steel core in such a way that the strips intersect with each other and the layers are interconnected with each other. using the rubber and / or plastic reinforcement. It has been found that in this combination of rubber or plastic and nonwoven fiber material, it is possible to obtain the combination of elasticity and resistance to large mechanical stresses required in connection with press or clamping rollers.

Fremstillingen af valser kan eksempelvis ske ved, at en bane af uvævet fibermateriale, f.eks. af helsyntetiske stabilfibre eller endeløse fibre, gøres dejagtig ved neddypning i et bad med opløst gummi eller gives affinitet over for gummi ved imprægning med en 5 egnet plast. Begge sider af den således præparerede fiberbane sammenpresses ved hjælp af en flervalsekalander med uvulkaniserede gummilag eller belægges med plast. Derved gennemtrænger det uvulkaniserede gummi eller den ikke-fugtede plast fuldstændigt fiberbanens porer, så at der senere efter befugtning opstår et 10 fiberforstærket gummi- eller plastbånd. Den endnu uvulkaniserede gummiarmerede eller ikke-befugtede plastarmerede fiberbane opvikles skruelinjeformet i form af smalle strimler på en stålkerne således, at strimlerne i til hinanden grænsende lag krydser hinanden. Det således opbyggede valselegeme af gummi- og/eller plastarmerede 15 fiberbanestrimler bliver derefter vulkaniseret eller befugtet. Senere bliver valselegemet drejet eller slebet således, at det bliver målrigtigt, centrisk og glat.The manufacture of rollers can be done, for example, by a web of nonwoven fibrous material, e.g. made of fully synthetic stable fibers or endless fibers, made doughy by immersion in a bath of dissolved rubber, or given affinity to rubber by impregnation with a suitable plastic. Both sides of the thus prepared fiber web are compressed by means of a multi-roll calender with unvulcanized rubber layers or coated with plastic. Thereby, the unvulcanized rubber or non-wetted plastic completely penetrates the pores of the fibrous web, so that a later, after wetting, a fiber-reinforced rubber or plastic tape is formed. The yet unvulcanized rubber-reinforced or non-wetted plastic reinforced fiber web is wound helically in the form of narrow strips on a steel core so that the strips intersect with each other. The roller body thus constructed of rubber and / or plastic reinforced fiber web strips is then cured or wetted. Later, the roller body is rotated or ground to become purposeful, centric and smooth.
Valselegemer af den her beskrevne art egner sig ikke blot f.eks.Rolling bodies of the kind described herein are not only suitable e.g.
20 til fremstilling af uvævede fiberbaner, men også som drivvalse i stålindustrien eller ved anvendelse af syrebestandige fibre og syrebestandigt bindemiddel også som valse til syre-, lud- og affedtningsbade .20 for the production of nonwoven fiber webs, but also as a drive roller in the steel industry or by using acid-resistant fibers and acid-resistant binder also as rolls for acid, liquor and degreasing baths.
25 En udførelsesform for en valse fremstillet ved fremgangsmåden ifølge opfindelsen vil nu blive beskrevet under henvisning til tegningen, der viser valsen set i perspektiv.An embodiment of a roller made by the method according to the invention will now be described with reference to the drawing which shows the roller in perspective.
Et valselegeme 2 er fastgjort på en stålkerne 1 og består af hinanden 30 krydsende lag af gummi- og/eller plastarmerede strimler 3 af et uvævet fibermateriale.A roller body 2 is secured to a steel core 1 and consists of each other 30 intersecting layers of rubber and / or plastic reinforced strips 3 of a nonwoven fibrous material.
Opfindelsen belyses yderligere ved de efterfølgende eksempler: 35The invention is further illustrated by the following examples:

Dette fibermateriale gennemvædes i en Foulard med en blanding af polyurethandispersion, tørres ved 150°C og kondenseres i 3 minutter ved 180°C, hvorved stoffet får o en færdigvægt på 200 g/m , og forholdet mellem fibre og binder er 5 70:30. Det således fremstillede fibermateriale skæres i f.eks. 100 mm baner og vikles op på et valselegeme i 2 lag med kant mod kant under en vinkel på f.eks. 50° og med sømoverlapning, idet der samtidigt finder en gennemvædning med polyurethan sted, dvs., at det netop tilsatte produkt (polyester/desmodur/desmophen) 10 påføres fibermateriale med et fugtemiddel (f.eks. glycol) ved 120°C. Forholdet fibermateriale: PU 5 1:3,Via a card is added a 140 g / m nonwoven fiber material with length-oriented fully synthetic fibers, e.g. of polyester fibers 3.3 - 17 dtex 3 143658 with a length of 60 or 80 mm. This fibrous material is soaked in a Foulard with a mixture of polyurethane dispersion, dried at 150 ° C and condensed for 3 minutes at 180 ° C to give a final weight of 200 g / m and the fiber to binder ratio is 5 70:30 . The fiber material thus produced is cut into e.g. 100 mm webs and wound on a roller body in 2 layers with edge to edge at an angle of e.g. 50 ° and with seam overlap, at the same time a soaking with polyurethane takes place, ie the newly added product (polyester / desmodur / desmophen) 10 is applied to fiber material with a wetting agent (eg glycol) at 120 ° C. Fiber material ratio: PU 5 1: 3,
Derefter fugtes denne valse i 48 timer ved 110°C, og valselegemet bliver så formet til mål og centricitet, idet overfladen afhængigt af 15 anvendelsesformålet drejes eller slibes.Then, this roller is moistened for 48 hours at 110 ° C and the roller body is then molded to measure and centricity, turning or grinding the surface depending on the application.

20 Via en kårde lægges et 100 g/m uvævet fibermateriale med længdeorienterede helsyntetiske fibre (f.eks. nylon 6.6 - 20 dtex, længde 60 eller 80 mm). Dette fibermateriale gennemvædes i en Foulard med en latex-dispersion (f.eks. butadien/styren/vinylpyridin-latex kombineret med resorcinharpiks - forhold 80:20), tørres ved 150°C20 A 100 g / m nonwoven fiber material with length oriented fully synthetic fibers (eg nylon 6.6 - 20 dtex, length 60 or 80 mm) is added. This fiber material is soaked in a Foulard with a latex dispersion (e.g., butadiene / styrene / vinylpyridine latex combined with resorcin resin ratio 80:20), dried at 150 ° C
25 og kondenseres i 3 minutter ved 180°C, hvorved færdigvægten o bliver 167 g/m , og forholdet mellem fibre og binder bliver 60:40.25 and condensed for 3 minutes at 180 ° C, whereby the final weight o becomes 167 g / m and the fiber to binder ratio becomes 60:40.
Derefter gøres fibermaterialet dejagtigt i en gummiopløsning og/eller gummieres på en flervalsekalander med gummifolier, der har en 30 vægt på 800 - 1000 g/m . Derved gennemtrænger det uvulkaniserede gummi fuldstændig homogent fibermaterialets porer. Det således fremstillede, med uvulkaniseret gummi armerede fibermateriale skæres så i f.eks. 10 mm baner og vikles med kant mod kant under en vinkel på f.eks. 40° lag for lag op på stålkernen. Det således 35 frembragte valselegeme vulkaniseres så 4 timer i en autoklav ved 143°C. Derefter formes valselegemet til mal og centricitet, idet overfladen alt efter anvendelsesformål afdrejes eller afslibes. Gummiblandingen kan sammensættes således, at den bliver syre- og kemikaliefast.Then, the fibrous material is made doughy in a rubber solution and / or rubberized on a multi-roll calender with rubber foils having a weight of 800-1000 g / m. Thereby, the unvulcanized rubber penetrates completely homogeneous pores of the fibrous material. The fiber material thus prepared with unvulcanized rubber is then cut into e.g. 10 mm webs and wound with edge to edge at an angle of e.g. 40 ° layer by layer on the steel core. The thus produced roller body is then vulcanized for 4 hours in an autoclave at 143 ° C. Then, the roller body is molded into mold and centricity, with the surface being peeled or abraded as needed. The rubber compound can be formulated to become acid and chemical resistant.
