Abstract
Description
15 20 25 30 35 502 650 2 grund av sin lilla diameter kan den utan större svårighet avlägsnas från pappersrullen. Due to its small diameter, it can be removed from the paper roll without much difficulty.
Uppfinningens ändamål och viktigaste kännetecken Ändamålet med föreliggande uppfinning är att åstadkomma ett förenklat sätt för framställning av en hylslös materialrulle, t.ex. pappersrulle med ett relativt stort centrumhål, varvid krävs en upprullningsspindel med motsvarande stor diameter.OBJECTS AND MOST IMPORTANT FEATURES OF THE INVENTION The object of the present invention is to provide a simplified method for producing a sleeveless material roll, e.g. paper roll with a relatively large center hole, in which case a winding spindle with a correspondingly large diameter is required.
Problemet att avlägsna upprullningsspindeln från pappers- rullen accentueras härmed.The problem of removing the winding spindle from the paper roll is hereby accentuated.
Enligt uppfinningen har detta problem lösts och det upp- finningsenliga sättet kännetecknas av att materialbanans begynnelseände läggs kring en icke-expanderbar upprullnings- spindel med en fast diameter på minst 35 mm och vilken spindel bringas att rotera för upplindning av materialbanan på spindeln, att på spindeln alternativt på det eller de första varven av materialbanan påföres ett friktions- reducerande medel i form av vatten med eventuell tillsats av mjukgörare eller smörjmedel avsett att reducera friktionen mellan materialbanan och spindeln, och att efter avslutad upprullning av materialbanan på spindeln denna utdrages ur den bildade rullen.According to the invention this problem has been solved and the method according to the invention is characterized in that the starting end of the material web is laid around a non-expandable winding spindle with a fixed diameter of at least 35 mm and which spindle is caused to rotate to wind the material web on the spindle. alternatively, on the first revolution (s) of the web of material, a friction reducing agent in the form of water is applied with the possible addition of plasticizer or lubricant intended to reduce the friction between the web of spindle and the spindle, and that it is pulled out of the formed roll. .
Beskrivning av ritninqa; Uppfinningen kommer i det följande att närmare beskrivas med hänvisning till ett på bifogade ritningar visat utförings- exempel.Description of the drawing; The invention will be described in more detail below with reference to an exemplary embodiment shown in the accompanying drawings.
Fig. 1 är en ändvy av en pappersrulle med centrummatning.Fig. 1 is an end view of a paper roll with center feed.
Fig. 2 och 3 visar schematiskt inledningen av upprullningen av en pappersbana enligt två olika metoder.Figs. 2 and 3 schematically show the beginning of the winding of a paper web according to two different methods.
Fig. 4 visar en upplindningsspindel enligt ett_alternativt utförande.Fig. 4 shows a winding spindle according to an alternative embodiment.
Beskrivning av utföringsexempel Pappersrullen 1 framställs genom att en fri ände 2a av en 10 15 20 25 30 35 502 650 3 _ pappersbana 2 förs i ingrepp med en upplindningsspindel 3 i en upplindningsmaskin. I utföringsexemplet enligt fig. 2 sker upprullningen på en s.k. bärvalsmaskin, i vilken upplind- ningsspindeln 3Vär anordnad mellan ett par bärvalsar 4, vilka roteras. I fig. 3 visas ett s.k. centrumdrivet system, i vilket själva upprullningsspindeln roteras. Enligt båda systemen kommer, när spindeln 3 roteras, papperet att lindas upp på spindeln, vilken efter avslutad upplindning dras ut ur den bildade pappersrullen.Description of exemplary embodiments The paper roll 1 is produced by engaging a free end 2a of a paper web 2 in a winding spindle 3 in a winding machine. In the exemplary embodiment according to Fig. 2, the winding takes place on a so-called support roller machine, in which the winding spindle 3 is arranged between a pair of support rollers 4, which are rotated. Fig. 3 shows a so-called center-driven system, in which the winding spindle itself is rotated. According to both systems, when the spindle 3 is rotated, the paper will be wound up on the spindle, which after completion of winding is pulled out of the formed paper roll.
För centrumutmatade pappersrullar krävs en relativt stor centrumöppning, ca 35-100 mm beroende på rullens dimension i övrigt. Även flertalet pappersrullar avsedda att rullas av från rullens periferi uppvisar centrumöppningar på mer än 35 mm. Upplindningsspindlar med motsvarande dimension är mycket svåra att dra ut ur den på spindeln upprullade pappersrullen. I synnerhet om en helt cylindrisk spindel används blir friktionen mycket stor, då anliggningsytan mellan papper och spindel är stor. En något lägre friktion erhålls för spindlar med ett icke-cirkulärt tvärsnitt. Enligt uppfinningen föreslås därför att man strax innan eller i samband med initieringen av upplindningen påför spindeln ett friktionsreducerande medel, avsett att reducera friktionen mellan pappersbanan och spindeln. Detta medel utgöres av vatten, eventuellt med tillsats av någon mjukgörare, t.ex. kvartär armin, eller annat smörjmedel såsom silikon eller liknande.For center-fed paper rolls, a relatively large center opening is required, approx. 35-100 mm, depending on the dimension of the roll in general. Most paper rolls intended to be unrolled from the periphery of the roll also have center openings of more than 35 mm. Winding spindles with a corresponding dimension are very difficult to pull out of the paper roll wound on the spindle. Especially if a completely cylindrical spindle is used, the friction becomes very large, as the contact surface between paper and spindle is large. A slightly lower friction is obtained for spindles with a non-circular cross section. According to the invention, it is therefore proposed that a friction reducing agent be applied to the spindle just before or in connection with the initiation of the winding, intended to reduce the friction between the paper web and the spindle. This agent consists of water, possibly with the addition of some plasticizer, e.g. quaternary arm, or other lubricant such as silicone or the like.
I fig. 1 visas att det friktionsreducerande medlet påföres spindeln 3 medelst ett spraymunstycke 4. Naturligtvis kan påförandet även ske på annat sätt, t.ex. genom påstrykning.Fig. 1 shows that the friction reducing agent is applied to the spindle 3 by means of a spray nozzle 4. Of course, the application can also take place in another way, e.g. by ironing.
Alternativt kan medlet, såsom visas i fig. 2, påföras det eller de innersta varven av pappersbanan 2 i stället för på spindeln 3.Alternatively, as shown in Fig. 2, the agent may be applied to the innermost turn (s) of the paper web 2 instead of to the spindle 3.
Det har överraskande visat sig att man får en väsentlig friktionsreduktion med enbart vatten. Detta kan förklaras med att när kräppat papper fuktas med vatten sker en töjning av papperet, vilken töjning består även efter torkning. 10 15 20 25 30 35 502 650 4 Töjningen medför att friktionen mellan papper och spindel reduceras. En ytterligare friktionsreduktion erhålls om man till vattnet tillsätter en mjukgörare eller annat smörjmedel, såsom nämnts ovan.It has surprisingly been shown that you get a significant reduction in friction with water alone. This can be explained by the fact that when creped paper is moistened with water, the paper is stretched, which stretching persists even after drying. 10 15 20 25 30 35 502 650 4 The elongation reduces the friction between the paper and the spider. A further friction reduction is obtained if a plasticizer or other lubricant is added to the water, as mentioned above.
Friktionen reduceras ytterligare om spindeln 3 värms i sam- band med att den friktionsreducerande substansen tillförs.The friction is further reduced if the spindle 3 is heated in connection with the addition of the friction-reducing substance.
Värmningen av spindeln kan antingen ske på elektrisk väg eller medelst ånga. I det senare fallet används företrädesvis en spindel 3 av det slag som visas i fig. 4, dvs. en ihålig spindel försedd med ett flertal radiella hål 5. Ãnga alter- nativt vatten som uppvärms på elektrisk väg inuti spindeln tillförs spindelns inre via en ledning 6 och får sedan strömma ut genom hålen 5. Vattnet som på detta sätt tillförs papperet i ångform penetrerar pappersbanan bättre än vatten som tillförs i flytande form.The heating of the spindle can be done either electrically or by steam. In the latter case, a spindle 3 of the type shown in Fig. 4 is preferably used, i.e. a hollow spindle provided with a plurality of radial holes 5. Young alternative water which is electrically heated inside the spindle is supplied to the interior of the spindle via a line 6 and is then allowed to flow out through the holes 5. The water thus supplied to the paper in steam form penetrates the paper web. better than water supplied in liquid form.
Genom värmningen av spindeln, antingen om värmningen sker på elektrisk väg eller medelst ånga, i kombination med fukt- tillförseln erhålls en strykjärnseffekt, dvs. fibrerna i det/de innersta varvet/varven av pappersbanan kompakteras och man får en slätare yta på papperet som anligger mot spindeln, varigenom friktionen mot spindeln reduceras. Dessutom på- skyndar värmningen torkprocessen.By heating the spindle, either if the heating takes place electrically or by steam, in combination with the supply of moisture, an iron effect is obtained, ie. the fibers in the innermost turn (s) of the paper web are compacted and a smoother surface is obtained on the paper abutting the spindle, thereby reducing the friction against the spindle. In addition, heating speeds up the drying process.
Spindeln 3 kan antingen vara cylindrisk, såsom visas i ritningen, men kan också uppvisa annan form med kuggar, bommar eller liknande, vilka eventuellt kan vara vridna i spiralform. Den kan även uppvisa en svagt konisk form för att underlätta utdragning ur pappersbanan. Spindeln kan vara av ett lågfriktionsmaterial eller uppvisa en beläggning av ett dylikt material. Exempel på lämpliga material är nylon, acetal, teflon eller lågfriktionsbehandlad metallegering.The spindle 3 can either be cylindrical, as shown in the drawing, but can also have another shape with teeth, booms or the like, which may possibly be twisted in a spiral shape. It can also have a slightly conical shape to facilitate extraction from the paper web. The spindle may be of a low friction material or have a coating of such a material. Examples of suitable materials are nylon, acetal, Teflon or low friction treated metal alloy.
Uppfinningen är inte begränsad till de visade utförings- exemplen, utan ett flertal varianter och modifieringar är tänkbara inom ramen för patentkraven.The invention is not limited to the exemplary embodiments shown, but a number of variants and modifications are conceivable within the scope of the claims.
