Papperet rullas av rullen 4 och fares Over en styrrulle 5, som tydligast framgar av fig. 1, 3 och 6, vilken styrrulle uppbares av konsoler 6 och 7, som Er anbragta i ramen 1. Papperet frail rullen 4 fores in mellan tva samverkande serier av roterbara knivar eller skivor 8 och 9, som Or anordnade pa inb6rdes avstand pa axlar och 11, sasom tydligt framgar av fig. 5. Axlarna 10 och 11 Or lagrade vid motsatta andar i lager 12 och 14, 15 och 16. Dessa lager Or anbragta i vertikalt sig strackande standare 17 och 18 och Or vertikalt installbara medelst installningsskruvar 19 och 20, som paverkas medelst manuellt reglerbara installningsrattar 21 och 22. Knivarnas eller skivornas 8 och 9 overlappningsgrad ãr fOljaktligen Mt installbar for motsvarande reglering av uppdelningsoperationen. Axlarna 10 och 11 drives samtidigt medelst kugghjul 23 och 24, som bar Under av sadan langd, att kugghjulen. 23 och 24 kan kontinuerligt drivas amen nar stor installning sker maim de roterande knivarna eller skivorna. In the drawings, 1 denotes a frame in the device shown, which frame supported posts 2, in which an axis! 3 is stored to support one mile 4 of paper in the form the roll comes from. paper machine. The paper is rolled by the roller 4 and passed over a guide roller 5, which is most clearly shown in Figs. 1, 3 and 6, which guide roller is supported by brackets 6 and 7, which are arranged in the frame 1. The paper frail roller 4 is inserted between two cooperating series of rotatable knives or discs 8 and 9, which Or are arranged at a mutual distance on shafts and 11, as is clear from Fig. 5. The shafts 10 and 11 Or are stored at opposite spirits in bearings 12 and 14, 15 and 16. These bearings Or mounted in vertically extending stands 17 and 18 and Or vertically installable by means of installation screws 19 and 20, which are actuated by means of manually adjustable installation knobs 21 and 22. The degree of overlap of the knives or discs 8 and 9 is consequently Mt installable for corresponding control of the splitting operation. The axles 10 and 11 are driven simultaneously by means of gears 23 and 24, which carried under such length, that the gears. 23 and 24 can be operated continuously when large installation takes place with the rotating knives or discs.

Knivarna eller skivorna 8 och 9 bibringas rotation medelst axlar 26, som är lagrade i ramen 1 och uppbar kugghjul 27, som ingriper med kugghjulet 24, varigenom knivarna fOljaktligen drives samtidigt. Axeln 26 straeker sig till den ena sidan av anordningens ram, sa.- som visas i fig. 1, och är forsedd med koniskt kugghjul 28, som ingriper med ett koniskt kugghjul 29, som är anbragt pa drivaxeln 2- - till en motor 31. Pappersmaterialet drages genom anordningen medelst friktionsrullar for var och en av strimlorna, som Midas. Dessa rullar fir betecknade med 32, 32a, 32b, 32c, 32d, 32e, 32f, 32g, 32h, 32i, 32j, 32k, 321, 32m, 32n, 32o, 32p, 32q och 32r, vilka fir anbragta pa axeln 33, som stracker sig till den ena sidan av maskinens ram och har ett koniskt kugghjul 34 pa anden, vilket ingriper med ett koniskt kugghjul 35 pa axeln 30. Friktionsrullarna 32-32r drives fOljaktligen samtidigt i samverkan flied narliggande friktionsrullar, som ai betecknade med 36, som var for sig samverkar med i det foregaende angivna friktionsrullar for att draga pappersstrimlorna genom anordningen och som fiven bildar stopporgan, i forhallande till vilka tvinningsoperationen av varje strimla kan utforas samtidigt. Pa grund av den pa papperet medelst friktionsrullarna 32-32r och samverkande rullar 36 utovade kraften drages papperet fram melJan de roterande knivarna eller skivorna 8 och 9 och overawes fran den upprullade banan i rullen 4 till strimlor, som visas vid 37, 37a, 37b, 37c, 37e, 37f, 37g och 37h. Omedelbart efter uppdelningen sprides dessa strimlor medelst spridareorgan 37, som har ett flertal uppat sig strackande, vertikalt anordnade atskiljningspinnar 39, mellan vilka strimlorna styres symmetriskt pa Cause sidor om pappersrullens 4 mitt genom pa inbordes avstand anordnade porslinsringar 40. De pi avstand fran varandra anordnade porslinsringarna fir anbragta i linje med de olika friktionsrullarnas mitt. I den pa ritningen visade anordningen visas antalet strimlor till nio, sa att de utforda operationerna pa varje strimla visas begransade till anordningens 15.ngsmedelplan och symmetriskt p0. dettas sidor. Det inses emellertid, att dar antalet formade, behandlade och tvinnade strimlor i maskinen enligt uppfinningen okas, fordelas strimlorna pa bada sidor av de som visats pa ritningarna, som ãr att betrakta sasom visade for uppfinningens beskrivning och ej for dennas begransning till det visade antalet. Strimlorna drages linjfirt genom anordningen medelst serierna av friktionsrullar, enskilt paverkade av rullarna 32e, 32f, 32g, 32h, 321, 32j, 32k, 321 och 32m. Under loppet av strimlornas linjara rOrelse fran ringarna 40 genom serierna av friktionsrullar behandlas strimlorna individuellt medelst vatska, som är anbragt i ett trag 41, i vilket en serie fuktrullar 42 delvis skjuter nod, och dar ytan ph fuktrullarna astadkomn-ier anliggning med pappersstrinalornas flata yta. Pappersstrimlorna bestryker var fOr sig ytan pa rullarna 42 och blir tillrackligt b5jliga for att mojliggora de enskilda strimlornas utsattande for tvinningsoperationen. The knives or discs 8 and 9 are rotated by means of shafts 26, which are mounted in the frame 1 and supported gears 27, which engage with the gear 24, whereby the knives are consequently driven simultaneously. The shaft 26 extends to one side of the frame of the device, as shown in Fig. 1, and is provided with a conical gear 28, which engages with a conical gear 29, which is mounted on the drive shaft 2- - to a motor 31 The paper material is drawn through the device by means of friction rollers for each of the strips, such as Midas. These rollers are denoted by 32, 32a, 32b, 32c, 32d, 32e, 32f, 32g, 32h, 32i, 32j, 32k, 321, 32m, 32n, 32o, 32p, 32q and 32r, which are mounted on the shaft 33, which extends to one side of the frame of the machine and has a conical gear 34 on the shaft, which engages with a conical gear 35 on the shaft 30. The friction rollers 32-32 are consequently driven simultaneously in cooperation with adjacent friction rollers, as indicated by 36, which each cooperates with the friction rollers specified above to pull the paper strips through the device and which fives form stop means, in relation to which the twisting operation of each strip can be performed simultaneously. Due to the force exerted on the paper by the friction rollers 32-32r and cooperating rollers 36, the paper is pulled between the rotating knives or discs 8 and 9 and overaws from the wound web in the roller 4 into strips, as shown at 37, 37a, 37b, 37c, 37e, 37f, 37g and 37h. Immediately after the division, these strips are spread by means of spreading means 37, which have a plurality of upwardly extending, vertically arranged separating pins 39, between which the strips are guided symmetrically on Cause sides of the paper roll 4 through inwardly spaced porcelain rings 40. fir placed in line with the center of the various friction rollers. In the device shown in the drawing, the number of strips is shown to nine, so that the challenging operations on each strip are shown limited to the mean plane of the device and symmetrically p0. its pages. It will be appreciated, however, that when the number of shaped, treated and twisted strips in the machine according to the invention is increased, the strips are distributed on both sides of those shown in the drawings, which are to be considered as shown for the description of the invention and not for limiting it to the number shown. The strips are drawn linearly through the device by means of the series of friction rollers, individually influenced by the rollers 32e, 32f, 32g, 32h, 321, 32j, 32k, 321 and 32m. During the linear movement of the strips from the rings 40 through the series of friction rollers, the strips are treated individually by means of liquid, which is arranged in a funnel 41, in which a series of moisture rollers 42 partially push node, and where the surface of the moisture rollers is arranged with paper surface terminals . The paper strips individually cover the surface of the rollers 42 and become sufficiently flexible to allow the exposure of the individual strips to the twisting operation.

Tvinningsoperationen sker i samma anordning utan strimlornas avlagsnande fran donna, i vilken varje strimla har ett fast lage vid friktionsrullarna 32e-32m och 36 och passe rar genom ett tvinningshuvud 43. Ett tvinningshuvud är anordnat for varje strimla, varvid huvudet har en slits 43a, genom vilken strimlan stracker sig. Varje tvinningshuvud 43 forsattes i rotation medelst en ganga 44 pa axeln 45, vilken ganga ingriper med ett snackhjul 43b i varje tvinningshuvud 43. De manga gangorna aro anordnade pa en axel 45, pa vilken är anbragt ett koniskt kugghjul 46, som ingriper med ett koniskt kugghjul 47 ph axeln 30. Tvinningshuvudet 43 fiirsattes i rotation med en hastighet, som är tillracklig for att tvinna resp. strimla inom det linjara avstandet mellan det fixa laget, som bildas av friktionsrullarna, och laget, som upptages av tviuningshuvudena. mom det linjara utrymmet mellan tvinningshuvudet och anordning en. for nystningen riktas varme mot varje tvirmad strang frail infraroda ljuskallor 48 och 49, varigenom de tvinnade stringarna, snorena, banden eller garnet avlamnas vid laget 50 och nystas pa spindlar 51. Varmen kan riktas mot lindningarna pa spolarna beroende pa det onskade slutresultatet. Spindlarna 51 forsattes samtidigt i rotation fran en axel 52 med ett koniskt kugghjul 53, som in-griper med ett koniskt kugghjul 54 pa axeln 30. Motorn 31 driver foljaktligen. alla anordningens delar for utforande av uppdelnings-, behandlings-, tvinnings-, torknings- och nystningsoperationerna, vilken. nystning sker pa for forsaljning avsedda spolar. Maskinen enligt uppfinningen dr aven utrustad med spannorgan Mr strimlorna och organ vid tvinnarna och spolarna for att medverka till strimlornas tvinning. Antalet spolar och strimlor av pap-per kan omspanna sextio till hundratjugo. Forfarandet enligt uppfinningen gOr det mojligt, att tillverka pappersgarn och pappersstrangar eller tradar behandlade med plast, harts, gummiderivater etc. for anvandning s0.som papperssnore eller pappersband. Varje strang torkas nfir den tillverkas och darigenom elimineras mojligheten av oriktigt fuktinnehall eller klibbighet, som annars kan uppkomma i ett fOrfarande, dar garn eller trad eller pappersprodukter torkas, nar den lindas pa en spole. Hela fOrfarandet, sa.dant det beskrivits i det foregaende, kan utforas med ett minimum av arbetskraft och tid pa grund av att flagon mellanhantering ej forekommer, nar papperet fir foremal for de olika stegen i forfarandet fran tidpunkten, nfir pappersrullen 4 anbringas pa axeln 3 till dess att spindlarna 51 uppbar de behandlade, tvinnade pappersstrangarna, ffirdiga att knytas, vavas eller saljas for manga olika findamal. The twisting operation takes place in the same device without the stripping of the strips from the mandrel, in which each strip has a fixed bearing at the friction rollers 32e-32m and 36 and passes through a twisting head 43. A twisting head is arranged for each strip, the head having a slot 43a, through which strip stretches. Each twisting head 43 was continued in rotation by means of a thread 44 on the shaft 45, which thread engages with a talk wheel 43b in each twisting head 43. The many passages are arranged on a shaft 45, on which a conical gear 46 is arranged, which engages with a conical gear 47 ph shaft 30. The winding head 43 was set in rotation at a speed sufficient to twist resp. shred within the linear distance between the fixed layer formed by the friction rollers and the layer occupied by the twin heads. mom the linear space between the twist head and device one. for coiling, heat is directed to each twisted string of infrared light sources 48 and 49, whereby the twisted strings, cords, ribbons or yarn are unloaded at layer 50 and coiled on spindles 51. The heat can be directed to the windings on the coils depending on the desired end result. The spindles 51 were simultaneously continued in rotation from a shaft 52 with a bevel gear 53, which engages with a bevel gear 54 on the shaft 30. The motor 31 consequently drives. all parts of the device for performing the splitting, processing, twisting, drying and kneading operations, which. spooling takes place on coils intended for sale. The machine according to the invention is also equipped with clamping means Mr the strips and means at the twists and coils for assisting in the twisting of the strips. The number of coils and strips of paper can span sixty to one hundred and twenty. The method according to the invention makes it possible to manufacture paper yarns and paper strands or threads treated with plastic, resin, rubber derivatives, etc. for use as paper strings or paper ribbons. Each strand is dried before it is manufactured, thereby eliminating the possibility of improper moisture content or tack, which may otherwise occur in a process where yarn or thread or paper products are dried when wound on a spool. The whole process, as described above, can be carried out with a minimum of labor and time because flake intermediate handling does not occur when the paper is formed for the various steps of the process from the time the paper roll 4 is applied to the shaft 3. until the spindles 51 carried the treated, twisted strands of paper, ready to be tied, waved or sold for many different purposes.

Forfarandet och anordningen enligt uppfinningen eliminerar den stora fOrlusit, som uppstar vid tidigare forfaranden. Kostnaderna per kilo produkt reduceras till ett stort minimum, pa grund av att arbetskraft sparas vid materialets hantering frail en operation till en annan. En battre produkt erhalles, pa — —3 o'rund av att forfarandet är kontinuerligt och mindre risk for brott eller knutar uppkommer i den fardiga produkten. En borttagbar pappers- eller plastkona eller spole kan fastas over spolen, och pappersgarnet, strangen eller bandet kan nystas direkt pa forstnamnda spole. Spolen kan foljaktligen avlagsnas frau bobinen efter det kontinuerliga forfarandet for tillverkningen, som beskrivits i det foregaende och den resulterande forpackningen kan saljas eller anvandas direkt i olika handelskanaler utan nOdvandigheten av ytterligare behandling eller hantering. The process and the device according to the invention eliminate the large loss which arises in previous processes. The costs per kilo of product are reduced to a large minimum, due to the fact that labor is saved when handling the material from one operation to another. A better product is obtained, due to the fact that the process is continuous and less risk of breakage or knots arises in the finished product. A removable paper or plastic cone or spool can be attached over the spool, and the paper yarn, string or tape can be wound directly on the former spool. Accordingly, the coil can be removed from the bobbin following the continuous manufacturing procedure described above and the resulting package can be sold or used directly in various commercial channels without the need for further processing or handling.

Uppfinningen liar beskrivits i anslutning till en foredragen utforingsform, men det är uppenbart, att uppfinningen kan bli foremal for modifikationer inom granserna for uppfinningstanken, sadan denna framgar av efterfoljande patentansprak. The invention has been described in connection with a preferred embodiment, but it is obvious that the invention can be the subject of modifications within the limits of the inventive idea, as it appears from the following patent claims.
