CLASS INTERNATIONAL SWEDISH D 03 c86b: 1 PATENT AND REGISTRATION AGENCY Ans. 1823/1958 received on 25/2 1958 issued on 16112 1963 J ZMATLIK ocx M JISA, PRAGUE, CZECHOSLOVAKIA Device for shell formation Priority requested free on 26 February 1957 (Czechoslovakia) The present invention relates to a shell forming device for obtaining a constant voltage and a minimal friction for the warp tractors in the manufacture of textiles.

Vid hittills anvanda forfaranden for framstallning av textilier har ingen konstant spanning hos varptradarna astadkommits och des- sa ha varit utsatta for en betydande 'Akanning genom foranderliga krafter oeh genom friktion. In the methods hitherto used for the manufacture of textiles, no constant tension has been achieved in the warp tractors and these have been subjected to a considerable 'Akanning by variable forces and by friction.

De hittillsvarande fahallandena vid vavning kannetecknas salunda ,av en ojamn spanning hos varptradarna vid skalbildningen och earntidigt en stor friktion mellan varpen och solvogonen. Detta dr anledningen till ett betydande antal varpbrott och driftsavbrott vid framstallningen av de fiesta textilsorter. Manga material kunna p5. grund harav overhuvud taget icke vavas industriellt. Dessutom aro dessa kanda betingelser has de hittillsvarande forfarandena for bildning av skalet ett hinder far h6ga vavstolshastigheter, en minimal kraft f6r tillslaget och sakerhetsstallning av en tillracklig renhet och storlek av skillet De forhindra vidare konstruktion av vavstolar med minimala dimensioner och darigenom aven med minimal energifOrbrukning vid maximal els.onomisk verkningsgrad. The hitherto failures in weaving can thus be drawn, by an uneven tension of the warp lines during the formation of scales and at the same time a great friction between the warp and the solvogon. This is the reason for a significant number of warp breaks and downtime in the production of most types of textiles. Many materials can p5. for this reason not at all vavas industrially. In addition to these known conditions, the hitherto methods for forming the shell have an obstacle to high wheelchair speeds, a minimum force for the impact and securing of a sufficient purity and size of the divider. maximum electrical efficiency.

De namnda olagenheterna elimineras genom att anordningen enligt uppfinningen erhallit de i patentanspralien angivna kanneteeknen, varvid uppnas aft spanningen has alla varptradarna blir lika oeh konstant, att tradfriktionen i solvogonen eller skalnalarna blir minimal och att skalvinkeln kan valjas godtyckligt .stor. Dessutom mOjliggor anordningen enligt uppfinningen bildandet av brâ eller flera skal samtidigt sa att vid va.vning av mat-tor, slangvaror eller dylikt tva eller flera in-slag kunna inforas pa en gang. Utforingsexempel pa uppfinningen skall nedan narmare beskrivas med hanvisning till bifogade ritningar. Fig. 1 visar i sektion ge- Dupl. kl. 86 c: 18/11 nom skalet, skaften, utjamningsstavarna, och strackbommen, fig. 2 samma som i fig. 1 vid andrad skaftstallning och fig. 3 ramen for lagringen av ett skaft och manovreringen av la-get hos den till detta skaft harande utjamningsstaven. The above-mentioned malfunctions are eliminated by the device according to the invention obtaining the pitches specified in the patent application, whereby the tension is obtained until all the warp threads become equal and constant, the thread friction in the solvogon or scale needles is minimal and the scale angle can be chosen arbitrarily large. In addition, the device according to the invention enables the formation of abrasive or several shells at the same time, so that when weaving mats, hose products or the like, two or more elements can be inserted at once. Exemplary embodiments of the invention will be described in more detail below with reference to the accompanying drawings. Fig. 1 shows in section ge- Dupl. at 86 c: 18/11 nom the shell, the shafts, the leveling rods, and the tension bar, fig. 2 the same as in fig. the leveling rod.

Skaften 1, 2 (fig. 1, 2) aro forsedda med solv lb, 2b, som har formen av en del av en eirkel och pa mitten aro forsedda med Ogon 1c, 2c. Medelpunkten hos de cirkelbagar, som bildas av solven, hos de bada skaften hefinner sig paStallet 3b, den s. k. vavlinjen som bildas dilr det senaste i skalet infOrda inslaget sibs till mot den genom varptradarna 4 och 5 framstallda vavnaden. Varptradarna 4, 5 Virus runt vridbara utjamningsstavar 6, 7, sum aro lagrade i icke visade styrningar i form av evolventer 8, 9 och runt den vridbara strackbommen 10. The shafts 1, 2 (Figs. 1, 2) are provided with silver lb, 2b, which has the shape of a part of a circle and in the middle are provided with eyes 1c, 2c. The center of the circular bags formed by the solvent in the two shafts is located on the stall 3b, the so-called wafer line which is formed by the last element inserted in the shell to the web produced by the warp lines 4 and 5. The warp lines 4, 5 Virus around rotatable leveling rods 6, 7, sum aro stored in guides (not shown) in the form of evolvers 8, 9 and around the rotatable tension bar 10.

Fig. 3 askadliggor ramen 11 hos skaftet 1, som ar vridbart lagrad pa en tapp 12 och drives av en dragstang 13, vilken ar ansluten till en godtycklig, kand, en tram- och aterga.ende rorelse utfOrande drivanordning. pa ramen 11 fir en tapp 14 anordnad, vars medelpunkt befinner sig i linje med medelpunkten f Or solyens lb Non lc. Fig. 3 damages the frame 11 of the shaft 1, which is rotatably mounted on a pin 12 and is driven by a tie rod 13, which is connected to an arbitrary, jaw, a tram and reciprocating movement performing drive device. on the frame 11 for a pin 14 arranged, the center of which is in line with the center of the sol lb Non lc.

Pa tappen 14 Sr ett lager 15 anordnat, vilket ar fast ombundet av ett runt utjamningsstaven 6 fort och p5 lagret 10b for strackbommen 10 fast stalband. Detta lager 10b har samma tvarsnitt och medelpunkt som strackbommen 10, SOM med sin tapp 10c ar vridbart lagrad i detta lager. Pa. utjamningsstavens 6 tapp 6b ar oglan hos en dragfjader 17 pasatt, scan med sin andra ande är fast i maskinramen och drar utjamningsstaven i pilens A riktning. On the pin 14 a bearing 15 is arranged, which is fixedly bound by a round steel band fastened around the leveling rod 6 and on the bearing 10b for the tensioning boom 10. This bearing 10b has the same cross-section and center point as the tension boom 10, which with its pin 10c is rotatably mounted in this bearing. Pa. the pin 6b of the leveling rod 6 is fitted to a tension spring 17, scan with its second spirit is fixed in the machine frame and pulls the leveling rod in the direction of the arrow A.

Den beskrivna anordningen fungerar folj ande satt. The described device works as follows.

Skaftets 1 ram 11 (fig. 3) drives genom dragstangens 13 fram- och aterghende rorelse pa sa salt att de genom skaftet 1 burna solven 2— — lb omvaxlande inta de i fig. 1 och 2 visade a.ndlagena. Den av fjadern 17 dragna utjamningsstaven 6 styres darvid av stalbandet 16 sã att dess axel ror sig langs evolventen 8. The frame 11 (Fig. 3) of the shaft 1 is driven by the forward and reciprocating movement of the drawbar 13 in such a salt that the solvents 2— - 1b carried through the shaft 1 alternately assume the ends shown in Figs. 1 and 2. The leveling rod 6 pulled by the spring 17 is thereby guided by the steel band 16 so that its axis moves along the involute 8.

Drivningen av de i skaftet 2 lagrade solven 2b och styrningen av utjamningsstaven 7 sker pa halt liknande satt som den beskrivna drivningen av solven lb och styrningen av utjamningsstaven6. The driving of the solvents 2b stored in the shaft 2 and the control of the leveling rod 7 take place in a manner similar to the described driving of the solvents 1b and the control of the leveling bar 6.

Vid andringen av skalet rOra sig solven lb, 2b, varptrAdarna 4, 5 och utjamningsstavarna 7, 8 fran den i fig. 1 visade stallningen forst till det i fig. 2 med streckade linjer antydda la-get och overgã slutligen till det i fig. 2 med heldragna linjer visade laget. When changing the shell, the solvents 1b, 2b, the warp rods 4, 5 and the leveling rods 7, 8 move from the position shown in Fig. 1 first to the layer indicated by dashed lines in Fig. 2 and finally pass to the position shown in Figs. 2 with solid lines showed the team.

Eftersom solvogonen lc, 2e i solven lb, 2b Tara sig i cirkelbagar, vilkas medelpunkter ligga pa. stallet 3b hos den blivande textilvaran 3 och utjamningsstavarnas 6, 7 axlar rora sig langs evolventerna 8, 9, vilka tillhora en med strackbommens 10 tvarsnittsomkrets identisk cirkel, ager vid skalbildningen ingen iimsesidig farskjutning rum vid varptradarnas 4, 5 beroringsstallen med solven lb, 2b och utjamningsstavarna 6, 7. Langden hos varptradarna 4, 5 mellan dessa beroringsstallen fOrblir alltid konstant, vilket stadkommes genom att laget hos utjamningsstavarna 6, 7 fran skaftens 1, 2 ramar pa.verkas av stalband, vilka i varje ogonbliek inta ett med laget av de i det respektive skaftet patradda varptradarna identiskt lage. Pa grund Wray forblir aven spanningen hos alla varptradarna alltid konstant. Since the solvogon lc, 2e in the solvency lb, 2b Tare themselves in circular bags, the midpoints of which lie on. the stable 3b of the future textile product 3 and the axes of the leveling rods 6, 7 move along the evolvers 8, 9, which belong to a circle identical to the cross-sectional circumference of the tension bar 10; the length of the leveling rods 6, 7. The length of the warp lines 4, 5 between these contact points always remains constant, which is achieved by the layer of the leveling rods 6, 7 from the frames of the shafts 1, 2 being actuated by steel bands, which at any one time in the respective shaft patraded warp traders identically lag. Due to Wray, the voltage of all the warp threads always remains constant.

Vid vavning av vavnader med flera inslag eller slagvavnader kunna tva eller flera skal bildas over varandra. Vid t. ex. mattvavning med tvd inslag bilda vid monsterinslaget de over det ovre inslaget bindande varptradarna det ovre skalet och de under det undre inslaget bindande varptradarna det undre skillet medan fyllnadsvarpen och de under det Ovre eller det undre inslaget bindande varptradarna forbli i mitten av skalet. When weaving fabrics with several elements or percussion fabrics, two or more shells can be formed on top of each other. At e.g. carpet weaving with two wefts form at the monster weft the warp-binding warts above the upper weft form the upper shell and the warp-binding warts below the lower part while the filling warp and the warp-binding warts under the upper or lower weft remain in the middle of the shell.

Utforandet av skaften 1, 2 avensom manovreringen av utjamningsstavarna 6, 7 kunna i konstruktivt avseende utforas pa talrika andra att. Alla anordningar vilkas andamdl iir att astadkomma att solvOgonen Tara sig pa sã satt att den momentana mittpunkten hos kriikningen hos den av solvOgonen tillryggalagda banan är identisk med stallet for invavningen av inslaget maste betraktas som endast en konstruktiv andring av forfarandet och anordningen enligt uppfinningen. Likasa maste alla anordningar for manOvrering av utjamningsstavarna, vilka ge samma resultat som anoTd ningen enligt uppfinningen, betraktas som endast konstruktiva andringar. Som exempel pa en sadan anordning kan en utforingsform an-Rims hos vilken utjamningsstaven manovreras hydrauliskt eller en utforingsform hos vii-. ken stalbandet 16 eller andra manOverorgan for utjamningsstaven aro belt utelamnade °eh den konstanta tradspanningen endast uppratthalles genom kraften av fjadern 17 eller av en annan pa utjan-mingsstaven 6 verkande, t. ex. pneumatisk anordning. The design of the shafts 1, 2 as well as the maneuvering of the leveling rods 6, 7 can be constructively performed on numerous others. All devices whose purpose is to cause the solvOgone to behave in such a way that the instantaneous midpoint of the crease of the web traveled by the solvOgone is identical to the place of weaving of the weft must be regarded as merely a constructive change of the method and device according to the invention. Likewise, all devices for maneuvering the leveling rods, which give the same results as the method according to the invention, are to be regarded as merely constructive changes. As an example of such a device, an embodiment can be provided in which the leveling rod is hydraulically operated or an embodiment of vii. The steel band 16 or other operating means for the leveling rod are slightly omitted, and the constant wire tension is only maintained by the force of the spring 17 or by another acting on the leveling rod 6, e.g. pneumatic device.
