Uppfinnare: E. R. Johansson. Inventor: E. R. Johansson.
F8religgande uppfinning hanfor sig till avlindning av varpen yid vaystolar och sarskilt till reglerad automatisk avlindning. Vid vav- ning sarskilt avt. ex. konstsilkevayna- tier är det av vikt, att varpen tyangsmassigt aylindas fran varpbommen i en takt, som mycket nara ansluter sig till den, med vilken varpen i varje ogonblick erfordras vid sjalva vavpartiet i vavstolen, och standigt halles under en i huvudsak konstant eller mom ett jamforelsevis begransat omrade varierande, relativt lag spanning. Konstsilketradarna aro namligen var for sig mycket tunna och slitas Hitt av, om belastningen ar f5r star eller varierar for mycket eller for plotsligt. Det dr ocksa av vikt, att man astadkommer en tillfredsstallande anpassning av avlindningen efter den under arbetets ghng alltmera minskande diametern has den pa varpbommen upplineade rullen cv varptradar. Denna varprune har merendels ursprungligen en diameter pa omkring 400-500 mm och avlindas till omkring 150 mm slutdiameter, da en Tarplangd pa ofta ett par km avlindats. The present invention relates to the unwinding of warp yid vay chairs and in particular to controlled automatic unwinding. When weaving, especially dept. ex. In the case of artificial silk vignettes, it is important that the warp is aylindass aylindas from the warp boom at a rate which adjoins very closely to that with which the warp is at any moment required at the actual crank portion of the crank, and is constantly held under a substantially constant or mom one comparatively limited range varying, relatively low voltage. Namely, the artificial silk threads are individually very thin and wear. Find out if the load is too high or varies too much or too suddenly. It is also important to achieve a satisfactory adjustment of the unwinding according to the increasingly decreasing diameter during the work, having the roller or warp tractor aligned on the warp boom. This warp rune mostly originally has a diameter of about 400-500 mm and is wound to about 150 mm final diameter, as a Tarpland of often a couple of km is wound.
Manga forslag ha tidigare gjorts for att anpassa avlindningen sa mycket som mOjligt efter vavstolens yarpbehov. Bland dessa markas sarskilt sadana, dar varpbommen drives _av en snackvaxel, som i sin tur matas Over en eller flera armar medelst ett i takt med vavstolens varpbehoy arbetande impulsorgart, som yanligen utgores ay en i beroende av slagbommen eller vavskeden fram och ater gaende slang. For att varpen skall hallas jamnt strackt under hela frammatningsprocessen, som brukar ske intermittent med accelerationsoch retardationsperioder, har man foreslagit att Ora skruven till snackvaxeln forskjutbar I axiell led relativt varpbommen, varvid den Mlles paverkad i derma led av en belastning av nagot slag, t. ex. en motvikt, en fjfiderkraft eller ett lod. Denna belastning är lampligen reglerbar, sa, att den kan anpassas t. ex. -efter olika material eller vavbredder. Tidigare har man ocksa andrat belastningen, alit .eftersom varprullens diameter minskat for att kompensera voNspanningens dammed minskande vridningsmoment. Many proposals have previously been made to adapt the unwinding as much as possible to the yarrow's yarp needs. Among these are especially those where the warp boom is driven by a snack shaft, which in turn is fed over one or more arms by means of an impulse actuator working in step with the warp chair's warp brace, which is preferably formed in a hose depending on the striking boom or warp spoon. In order for the warp to be kept evenly stretched during the entire feeding process, which usually takes place intermittently with acceleration and deceleration periods, it has been proposed that the Ora screw to the snack shaft be displaceable axially relative to the warp boom, thereby affecting Mlles in this direction by a load of some kind. ex. a counterweight, a spring force or a weight. This load is suitably adjustable, so that it can be adapted e.g. -according to different materials or hub widths. In the past, the load has also been changed, albeit as the diameter of the warp roll has decreased to compensate for the damping torque of the winding voltage.
Foreliggande uppfinning avser nu vissa fbrbattringar i samband med avlindnigsanordningar av delta slag. Vid sildana avlindningsanordningar, dar varpbommen med densamma drivande snackvaxel Or fast i en, i t. ex. gej der, relativt anordningens stativ hoj- och sankbar konsol, liar man tidigare brukat justera varphommens hojdlage for hand, da yarprullen pa grund av den fortskridande avlindningen minskat sã mycket i diameter, att ayvikelscn Iran den efterstravade konstanta inmatningsriktningen av yarpen in i vavstolen blunt for stor. Med de krav pa precision och arbetsbesparing, som man numera liar, Or en sadan anordning ieke tillfredsstallande, och det Or nu uppfinningens framsta andamal att ge medel for forbattring i detta avseende. The present invention now relates to certain improvements in connection with winding devices of the delta type. In the case of such unwinding devices, the warp boom with the same driving snack shaft Or is fixed in one, in e.g. gej der, relative to the device's stand hoj- och sankbar bracket, liar one previously used to adjust the height of the warp homme by hand, as the yar roll due to the advancing unwinding decreased so much in diameter that ayvikelscn Iran the desired constant feed direction of the yar into the loom blind for Big. With the demands on precision and labor saving which are now being made, such a device is not satisfactory, and it is now the foremost object of the invention to provide means for improvement in this respect.
Enligt uppfinningen skall darfor konsolen vara forbunden med en lyftmekanism, sons payerkas av elf efter vavstolens varpbehov arbetande impulsorgan, sO att konsolen automatiskt holes. Uppfinningen Or ay sfirskilt intresse i sadana anordningar, dar snackvaxelns skruv Or axiellt rarlig och utsatt for en axiell, varpspanningen motbalanserande belastning, och darvid bar konsolen vara anordnad att uppbara en kring en vridningsaxel vridhar, snackskruven axiellt paverkande strackregleringshavarm, sons i sin tur pa variabelt ay-stand fran sagda yridningsaxel men pa konstant niva relativt anordningens stativ paverkas an ett belastningen overfOrande tryckorgan, lampligen en, t. ex. med en roterbar trissa forsedd arm, som Or vridbart monterad pa en relativt stativet stational. del. Lyftmekanismen, som lampligen utgores av skruv och mutter, varav den ena Or fast i konsolen och den andra i stativet och endera anordnad att likriktat kringvridas av impulsorganet, kan yam sa anordnad, att den genom impulsorganet lyfter snarare nagot for mycket On for litet, da den Or i funktion. En utf5ringsform an uppfinningen kannetecknas darvid an ett kanselorgan anordnat att, anliggande mot 2— — varprullens periferi, bringa lyftmekanismen i funktion, nar varprullens hogsta punkt befinner sig under en viss forutbestamd niva., och fir funktion, nar den forutbestamda nivan uppnatts. According to the invention, therefore, the bracket must be connected to a lifting mechanism, the son's payer is driven by an impulse means operating according to the warp chair's warping needs, so that the bracket automatically holes. The invention is of particular interest in such devices, where the screw shaft screw is axially inclined and subjected to an axial, warp tension counterbalancing load, and the bracket should be arranged to support a rotary shaft rotating about the axis of rotation, the screw screw axially acting on the tension control arm, in turn ay-position from the said axle of rotation but at a constant level relative to the frame of the device is affected by a load transmitting pressure means, suitably one, e.g. with a rotatable pulley provided arm, which Or rotatably mounted on a relatively rack stationary. part. The lifting mechanism, which is suitably made up of screw and nut, one of which is fixed in the bracket and the other in the stand and either arranged to be rotated uniformly by the impulse means, can be arranged so that it lifts through the impulse means rather a little too much. the Or in operation. An embodiment of the invention can then be characterized by a chancel member arranged to, abutting against the periphery of the warp roll, activate the lifting mechanism when the highest point of the warp roll is below a certain predetermined level, and for function when the predetermined level is reached.
Dâ det merendels stiller sig lampligt att lata det fram och &ter gaende impulsorganet arbeta pa samma niva relativt stativet, uppstar problemet att praktiskt Erverfora matningsrorelsen till snackskruven, som ju undan for undan hojer sig. Enligt en utf8ringsform av uppfinningen loses detta problem darigenom, att impulsorgan.et ar anordnat att verka pa en kring en i fOrhallande till stativet stationar axel vridbar lophavarm, som ar anordnad att, lampligen Over en trissa, ligga an emot och paverka en varpbommens snackaxel direkt eller indirekt matande, i konsolen monterad regleringshavarm pa ett efter varprullens (minskande) diameter beroende (xninskande) avstand frau regleringshavarmens vridningsaxel. When it is mostly appropriate to let the reciprocating impulse member work at the same level relative to the stand, the problem arises of practically acquiring the feed movement to the screw, which gradually rises. According to an embodiment of the invention, this problem is solved in that the impulse means is arranged to act on a barrel arm rotatable about an axis rotating in relation to the frame, which is arranged to, abruptly over a pulley, abut and actuate the snack shaft of the warp boom directly. or indirect feeding, adjusting control arm mounted in the bracket at a (decreasing) distance depending on the (decreasing) diameter of the warp roll from the axis of rotation of the control holding lever.

Ritningen visar ena sidan av en varpbomstol sedd Iran insidan och utrustad med anordningar enligt uppfinningen. The invention will now be described in connection with an embodiment shown in the accompanying drawing, which constitutes an example of how the principle of the invention can be realized but which in no way is intended to limit the scope of the invention. The drawing shows one side of a warp boom chair seen Iran inside and equipped with devices according to the invention.

The warp boom is carried of the drive plate 6 with the pin pin 9. In engagement with the gear 7 is the screw 10, which is wedged on the shaft 11, which in its one end carried a gear 13 grooved with handle 12 and in its other spirit is mounted in a bottomed sleeve 14 with a comparatively narrow axial air duct 15. A sleeve 14 corresponding to tube 20 may also be arranged to enclose the shaft 11 in the other end. The sleeve 14 rests axially displaceably on a roller 16, and a corresponding roller 17 can be arranged for the tube 20 resp. corresponding part of the shaft 11, especially if this shaft part is not subjected to an upward force during feeding (the arm 25 lifts). The arc rollers are mounted in the bracket 2 by means of the shafts 18 resp. 19 and are suitably provided with spares formed after the sleeve resp. rudder or shaft. The screw 10 and the rollers 16 and 17 are suitably arranged in a common, oil-filled housing. that the latrability of the parts should be favored.
Nedtill pa konsolen 2 är i ett Ora 21 regleringshavarmen 22 lagrad kring axeln 23. I .ett stycke med och vinkelratt mot denna hav- arm eller som en sarskild pa axeln 23 lagrad arm befinner sig vinkelhavarmen 24, som i sin ytterande Or ledat 27 f8rbunden med matningsarmen 25, vilken medelst en kulled eller axeln 28 Or forbunden med en rondell, pa vilken den eller de med tandhjulet 13 sam- verkande sparrarna 20 Oro anbringade.

Denna havarm formedlar det genom armen 33 overfOrda motviktstrycket till snackskruven 10-14. At the bottom of the bracket 2, in an Ora 21, the control lever 22 is mounted around the shaft 23. In a distance perpendicular to this sea arm or as a special arm mounted on the shaft 23, the angle lever 24 is located, which in its outer O joint 27 is connected with the feed arm 25, which by means of a ball joint or shaft 28 Or is connected to a disc, on which the ratchet 20 Oro cooperating with the gear wheel 13 is mounted. The arms 22, 24 and 25 are held in a raised position by means of the spring 29. In the bearing bracket 60 fixed in the bracket 2, the tension control lever 62 is mounted around the pin 61 at a constant position from the snack shaft. This sea arm conveys the counterweight pressure transmitted through the arm 33 to the snack screw 10-14.
Mellan strackregleringshavarmen 62 och regleringshavarmen 22 Or en avstandslank 63 anordnad vridbar kring tappen 65 i armen 62. och lopande i en bygel 64 fast i konsolen 2. Deana lank 63 kan lampligen vara reglerbar till sin langd, t. ex. genom att best& av tva I forhallande till varandra skjutbara delar. Between the tension control lever 62 and the control lever 22 Or a spacer 63 arranged rotatably around the pin 65 in the arm 62. and running in a bracket 64 fixed in the bracket 2. This link 63 can suitably be adjustable to its length, e.g. by consisting of two parts slidable relative to each other.
Slutligen Or i konsolen 2 fast en mutter 40, som samverkar med en i stativet lagrad skruv 41, genom vilken konsolen med alla darpi fasta detaljer kan h8jas och sankas. Finally, a nut 40 is fixed in the bracket 2, which cooperates with a screw 41 mounted in the frame, through which the bracket with all the darpi fixed details can be raised and collected.
I stativet ar den med regleringshavarmen 22 samverkande lophavarmen 51 lagrad kring axeltappen 52. I lophavarmen 51 Or den frail vavstolens vavparti kommande, fram och Ater gaende impulsstangen 53 lagrad kring tappen 54. Vidare ar en mot regleringshavarmen 22' anliggande trissa 55 lagrad i lophavarmens 51 topp kring tappen 56. In the stand, the running arm 51 cooperating with the regulating arm 22 is mounted around the shaft pin 52. In the running arm 51, the impulse rod 53 coming from the free hub is mounted around the pin 54. Furthermore, a pulley 55 abutting the regulating arm 22 'is mounted in the running arm 51. top around the pin 56.
Pa lophavarmen 51 Or ocksa hakarmen 50) lagrad kring tappen 57. Denna hakarm 50 samverkar med tandhjulet 49, som Or fast fOrbundet med axeln 48, pa vilken det koniska kugghjulet 43 Or fastkilat. Detta ingriper i det med skruven 41 forbundna koniska kugghjulet 42, varigenom en av hakarmen 50 d.stadkommen vridning av tandhjulet 49 fortplantas till skruven 41, som i sin tur meddelar muttern 40 och claimed konsolen 2 en vertikalrorelse. Tandhjulets axel 48 gar tvars genom varpbomsstolen till det motsatta stativet och uppbar dar ett koniskt kugghjul motsvarande kugglijulet 43, som samverkar med ett kugghjul och en skruv motsvarande kugghjulet 42 och skruven 41.- P0. stativet 1 Or vidare konsolen 31 fast. Denna uppbar medelst axeln 32 strackloparmen. 33, som i sin andra ande har en kring tappen 34 roterbar trissa 35. Pa axeln 32 verkar den pa armen 36 forskjutbara motvikten. 37, sa att trissan 35 kommer att standigt utova ett storre eller mindre tryek axiellt mot skruvaxeln 11 Over streckregleringshavarmen 62. On the barrel arm 51 or also the hook arm 50) is mounted around the pin 57. This hook arm 50 cooperates with the gear 49, which is fixedly connected to the shaft 48, on which the bevel gear 43 is wedged. This engages the conical gear 42 connected to the screw 41, whereby a rotation of the gear 49 effected by the hook arm 50 is propagated to the screw 41, which in turn notifies the nut 40 and the claimed bracket 2 a vertical movement. The shaft 48 of the gear goes transversely through the warp boom seat to the opposite frame and carries there a conical gear corresponding to the gear 43, which cooperates with a gear and a screw corresponding to the gear 42 and the screw 41.- P0. the stand 1 Or further the console 31 fixed. This carried by means of the shaft 32 the stretching arm. 33, which in its second spirit has a pulley 35 rotatable about the pin 34. On the shaft 32 the counterweight displaceable on the arm 36 acts. 37, so that the pulley 35 will constantly exert a greater or lesser pressure axially against the screw shaft 11 above the line control lever 62.
Pa varprullens 4 Overdel rullar en i hakarmslyftaren 58 lagrad trissa eller vats 59. On the upper part of the warp roll 4 a pulley or wadded 59 stored in the hook arm lifter 58 rolls.
Denna lyftare 58, som Riper axiellt i pa ritningen icke visade lager i stativet 1, vilar med sin tyngd pa. varprullen 4. Nedtill har lyfta- ren 58 en hake 47 som fattar under hakarmen 50. Skulle varprullen 4 hojas otillb8r- ligt, lyftes hakarmslyftaren 58, sonl i sin tur lyfter hakarmen 50, sa att lyftningen av konsolen 2 avbrytes. — —3 Den nu beskrivna och pa ritningen visade anordningen fungerar pa foljande satt. Nar genom impuls Iran vavstolen impulsstangen 53 drages at hoger, kommer regleringshavarmen 22, vinkelhavarmen 24 och matararmen 25 att sd.ttas i rorelse, sâ att sparrhaken 26 matar fram skruven 10 en viss vridningsvinkel. Darvid kommer kugghjulet 7 med den armed fast forbundna varpbommen att vridas medurs, sh att Tarp avlindas. Skruvaxeln 11 star harvid under belastning av motvikten 37 over armarna 36, 33 och 62, sa att om avlindningen skulle leverera mera varp an vad som vavstolen fOr Ogonblicliet fOrbrukar, skruvaxeln 11 med skruven 10 f8rskjutes nagot at hoger, varvid kugghjulet 7 vrides moturs eller hammas mer eller mindre i sin av skruvens rotation astadkomna medursvridning. Kugghjulet 7 rullar harvid sa att saga pa skruven som om denna yore en kuggstang. Skruvens axiella rorelse kan ske utan storre motstand, da den Or lagrad pa rullarna 16 resp. 17, vilka kunna lopa ph kullager. Den axiella rorelsen kan ske dampat, darigenom att sjalva axeln 11 Or Iagrad i hylsan 14, som f8rmedlar trycket fran motvikten 37. Den luft som i vissa lagen befinner sig mellan axelAuden av axeln 11 och hylsans 14 botten pressas david ut genom kanalen 15, vilket medger en god dampning, som kan goras battre darigenom att kanalen 15 mynnar mot en hearbetad yta pa armen 62. Genom att axeln 11 Or lagrad i hylsan 14 resp. roret 20 minskas ytterligare motstandet mot skruvens axiella r8relse och underlattas axelns vridning. This lifter 58, in which Riper axially in the drawing not shown in the drawing 1 in the frame 1, rests with its weight on. the warp roller 4. At the bottom, the lifter 58 has a hook 47 which grips under the hook arm 50. Should the warp roller 4 be raised improperly, the hook arm lifter 58 is lifted, which in turn lifts the hook arm 50, so that the lifting of the bracket 2 is interrupted. - —3 The device now described and shown in the drawing works as follows. When the impulse Iran hub chair is pulled to the right by the impulse Iran, the control lever 22, the angle lever 24 and the feed arm 25 will be set in motion, so that the ratchet 26 advances the screw 10 at a certain angle of rotation. Thereby, the gear 7 with the armed fixed warp boom will be turned clockwise, so that the Tarp is unwound. The screw shaft 11 is then under load of the counterweight 37 over the arms 36, 33 and 62, so that if the unwinding were to deliver more warp than what the loom for the Ogonblicliet consumes, the screw shaft 11 with the screw 10 is moved slightly to the right, whereby the gear 7 is turned counterclockwise more or less in its clockwise rotation achieved by the rotation of the screw. The gear 7 then rolls so as to saw on the screw as if it were a rack. The axial movement of the screw can take place without much resistance, as it is mounted on the rollers 16 resp. 17, which can loop ph ball bearings. The axial movement can take place by steam, by the shaft 11 itself being mounted in the sleeve 14, which transmits the pressure from the counterweight 37. The air which in some layers is between the shaft of the shaft 11 and the bottom of the sleeve 14 is thereby forced out through the duct 15, which allows a good damping, which can be improved by the channel 15 opening towards a worked surface on the arm 62. By the shaft 11 being mounted in the sleeve 14 resp. The rudder 20 further reduces the resistance to the axial movement of the screw and allows the rotation of the shaft.
Nar stangen 53 vander tillbaka och air sig. at vanster ror sig ocksa. lophavarmen 51 med trissan 55 at vanster foljd av regleringshavarmen 22 ph grund av fjaderns 29 inverkan. Havarmen 22, matningsarmen 25 och sparren 26 komma salunda att aterforas till ett nytt matningslage. Skulle nu snackan 10 ha rort sig At hoger p0 grund av for star matning av varp vid foreghende slag hos impulsstangen 53, kommer strackregleringshavarmen 62 att ha vridit sig nagot 01 hoger i kontakt med hylsan 14 och foljaktligen kommer avstandslanken 63 ocksa att ha forskjutits at hoger. Vid sin motursroreise kommer regleringshavarmen 22 da att stota mot andytan av avstandslanken 63 och lata lopha-varmen 51 fortsatta i enlighet med det fulla siaget av impulsstangen 53. Nar denna gor sitt nasta slag, kommer lophavarmen 51 att fanga upp regleringshavarmen 22, dar den lamnades i kontakt med avstandslanken 63, och havarmans 22, havarmens 24, armens 25 on sparrens 26 slag kommer att bli kortare, sh att en mindre matning av varpen ager rum. Oin mera varp skulle erfordras. On vad som i verkligheten frammatas genom slaget, kommer varpspanningen att bringa den nu accelererade varpbommen att rotera nagot mera On matningen av snackan 10 mot motvikten 37. Dar- igenom kommer snackan 10 och dess axel 11 att f8rskjutas at vanster och avstandslanken 63 kommer da ocksa att rora sig at vanster, darigenom tillatande regleringshavarmen 22 att gra ett storre slag nasta gang for att kompensera underskottet vid foreghende matningsslag. When the rod 53 wanders back and airs itself. that vanster moves too. the running arm 51 with the pulley 55 to the left followed by the regulating arm 22 ph due to the action of the spring 29. The sea arm 22, the feed arm 25 and the raft 26 will thus be returned to a new feed type. Should the snack 10 now have moved At right due to excessive feeding of warp at the previous stroke of the impulse rod 53, the tension control holder 62 will have turned slightly 01 right in contact with the sleeve 14 and consequently the distance link 63 will also have shifted to the right. . During its counterclockwise travel, the control lever 22 will then strike the front surface of the spacer 63 and allow the loop heater 51 to continue in accordance with the full throttle of the impulse rod 53. When this makes its next stroke, the loop arm 51 will catch the control lever 22 when it was paralyzed. in contact with the distance link 63, and the stroke of the warbler 22, the limb arm 24, the arm 25 and the rafters 26 will be shorter, so that a smaller feeding of the warp takes place. No more warp would be required. On what is actually advanced through the stroke, the warp tension will cause the now accelerated warp boom to rotate slightly more. to move to the left, thereby allowing the control holder 22 to make a larger stroke next time to compensate for the deficit at the previous feed stroke.
Alit eftersom varpen avlindas frail varprullen 4 minskar dennas diameter. Vid varje slag som impulsstangenOr frammatas varprullen en viss vinkel, men dd. denna yinkelvridning ger storre langd av avlindad varp ju stone varnrullens diameter Or och vavstolen standigt behover konstant langdinatning Or enligt uppfinningen en korrektion for varprullens diameterminskning inford. Denna tiligar pa sh salt, att regleringshavarmen 22 paverkas ph storre eller mindre avstand fran sin vridningsaxel 23 av trissan 55 darigenom, att lophavarmen 51 Or forskjuthar relativt armen 22, vilket kan astadkommas pO manga olika satt, t. ex. genom att armen 51 undan for undan matas nedat. Dot kan ocksa tankas att stangen 53 bringas att direkt verka pa regleringshavarmen 22 pa olika stallen. Vid utforandet enligt ritningen sker korrektionen pa sh satt, att en pa lophavarmen 51 fast hakarm 50 vid varje slag av stangen 53 paverkar tandhjulet 49 och darmed srider axeln 48 och kugghjulet 43 som i sin tur vrider kugghjulet 42 och skruven 41. Eftersom denna skruv sitter fast i stativet, kommer dess i konsolen 2 fasta mutter 40 att skruvas upp i motsvarighet till hakarmens matning. Darmed lyftas °ash konsolen 2 med darpa fasta detaljer, sarskilt regleringsha-varmen 22, skruvvaxeln 7, 10-14 och strackregleringshavarmen 62. Matningen Or sa avpassad, att varprullens toppunkt alltid befinner sig ph samma niva. Skulle matningen emellertid bli for stor, kommer enligt det visade utforandet hakarmslyftaren 58 att lyftas och haken 47 att lyfta upp hakarmen 50, sh att den kommer ur ingrepp med tandhjulet 49, till dess varprullens toppunkt sjunkit genom avlindningen. Alit because the warp is unwound from the warp roll 4 reduces its diameter. At each stroke as the impulse rodOr the warp roll is advanced a certain angle, but dd. this angular rotation gives a greater length of unwound warp, but the diameter of the warp roll and the loom constantly need constant longitudinal insertion. Or according to the invention a correction for the diameter reduction of the warp roll is introduced. This is due to the fact that the regulating arm 22 is affected at a greater or lesser distance from its axis of rotation 23 by the pulley 55 in that the running arm 51 shifts relative to the arm 22, which can be achieved in many different ways, e.g. by slowly feeding the arm 51 downwards. It is also conceivable that the rod 53 is caused to act directly on the control holder 22 in different places. In the embodiment according to the drawing, the correction takes place in such a way that a hook arm 50 fixed to the barrel arm 51 at each stroke of the rod 53 acts on the gear 49 and thereby rotates the shaft 48 and the gear 43, which in turn turns the gear 42 and the screw 41. fixed in the frame, its nut 40 fixed in the bracket 2 will be screwed up corresponding to the feed of the hook arm. This lifts the axle bracket 2 with darpa fixed details, in particular the control lever 22, the screw shaft 7, 10-14 and the tension control lever 62. The feed Or is so adapted that the top of the warp roller is always at the same level. However, should the feed become too large, according to the embodiment shown, the hook arm lifter 58 will be lifted and the hook 47 will lift up the hook arm 50, so that it comes out of engagement with the gear 49, until the top of the warp roll has sunk through the unwinding.
Eftersom regleringshavarmen 22 paverkas alit narmare sin vridningsaxel ju hogre konsolen uppskruvats, kommer armens 22 av slaget hos stangen 53 astadkomna vridningsvinkel att successivt Oka, vilket medfor en successivt okande matning av tandhjulet 13 och darmed av varpbommen Over skruvvaxeln. samma salt kommer mot viktens 37 av strackregleringshavarmen 62 formedlade anliggningstryck mot axeln 11 att minska undan far undan ju mindre varprullens diameter blir, vilket star i overensstammehe med att varpspanningens vridningsmoment minskar med minskande diameter has varprullen. Since the control lever 22 is affected more closely to its axis of rotation the higher the bracket is screwed, the angle of rotation of the arm 22 of the rod 53 will gradually increase, which results in a successively increasing feed of the gear 13 and thus of the warp boom over the screw shaft. the same salt will, against the weight 37 of the abutment control lever 62 mediated abutment pressure against the shaft 11, decrease less and less as the diameter of the warp roll becomes smaller, which is in line with the fact that the torque of the warp tension decreases with decreasing diameter of the warp roll.
Givetvis kunna manga av de i samband med ritningen beskrivna detaljerna ersattas med ph samma eller likartat salt verkande anordningar. Impulsstangen 53 kan vara ersatt av en wire eller en kedjeanordning eller ocksa_ — kan impulsen uttagas ph elektrisk vag. Eventuellt kan excentrar anvandas i detta sammanhang. Impulsstangen 53 e. d. kan bring-as att verka mot regleringshavarmen 22 direkt, varTid armen Mlles i bestamt lige, medan regleringshavarmen 22 ror sig shsom visats pa ritningen. Harvid kan det Tara lampligt att utforma armen 22 med en ph lampligt satt krokt bana for anliggningen mellan stangen 53 och armen 22. .Of course, many of the details described in connection with the drawing can be replaced with the same or similar salt-acting devices. The impulse rod 53 can be replaced by a wire or a chain device or also - the impulse can be taken out electrically vaguely. Eccentrics may be used in this context. The impulse rod 53 or the like can be caused to act against the control holder 22 directly, during which time the arm is measured in a certain straight line, while the control holder 22 moves as shown in the drawing. In this case, it may be appropriate to design the arm 22 with a suitably set curved path for the abutment between the rod 53 and the arm 22..
