Definitions

  • ABSTRACT Thread guiding device for ring spinning and ring twisting frames includes a ring having a radially inner engagement surface and a bottom engagement surface, and an ear-shaped traveller mounted on the ring for traveling around the same, the traveller being in engagement only with the inner and bottom engagement surfaces of the ring in the course of travel thereof about the ring.
  • Such thread guiding devices for ring spinning and ring twisting frames are formed generally from socalled flange rings with C-shaped or elliptical travellers that are mounted thereon. They are preferably used for spinning and for fine twisting.
  • a disadvantage of these thread guiding devices is that the speed of travel of the traveller cannot exceed a predetermined maximum because of unfavorable lubrication conditions. Numerous attempts to increase the traveller speed by varying the mutual engagement surfaces of the ring and the traveller have not had any salutary results.
  • a thread guiding device for ring spinning and ring twisting frames comprising a ring having a radially inner engagement surface and a bottom engagement surface, and an ear-shaped traveller mounted on the ring for travelling around the same, the traveller being in engagement only with the inner and bottom engagement surfaces of the ring in the course of travel thereof about the ring.
  • Rings with ear-shaped ring travellers are, in fact, known, having been used essentially only for twisting. These ear-shaped ring travellers do not however engage the ring only at the radially inner surface thereof but rather, due to the inclined position of the traveller caused by the thread path or pull, also engage the underside and the upper side of the ring.
  • the thread or yarn accordingly runs either through a pocket formed in the ring traveller, or the ring is provided with a recess which affords the yarn or thread space for an adequate passing therethrough.
  • the ring traveller does not engage the ring at the upper side or surface thereof, so that features such as the provision of a pocket in the ring traveller or a recess in the ring are dispensed with.
  • Adequate space for passage therethrough of the yarn or thread is provided between the ring traveller and the upper surface of the ring in accordance with the invention, as is attained otherwise only for c-shaped travellers.
  • the radius of curvature of the traveller and of the ring in the vicinity of the uppermost limit of contact between the ring and the ring traveller, i.e. in the vicinity of the zone at which the thread being processed is passed through the traveller is of significance.
  • the forces exerted on the ear-shaped ring traveller do not only force the traveller against the radially inner surface of the ring but also apply considerable pressure of the foot of the traveller against theunderside or bottom surface of the ring.
  • the radially inner surface of the ring engaged by the ring traveller in addition to the curvature thereof, has an inclination to the horizontal of from 4-14, preferably 10, in the sense of an increase of diameter in a downward direction. In this manner, a considerable portion of the upwardly directed tension components of the ring traveller that originate from the thread path or pull is compensated, as is more fully explained hereinafter with regard to the description of the illustrated embodiments.
  • a lubrication supply device is connected to the surface of the ring engaged by the traveller.
  • the thread guiding device presents the marked advantage that the traveller can no longer ride with its edge on the ring, which considerably increases the longevity or durability thereof, and fiber fly forming between the ring traveller and the upper surface of the ring is driven off to the outside.
  • advantages have been obtained for the ocnventional rings with ear-shaped ring travellers when employing the invention of the in stant application which were obtainable heretofore only with difficulty or were not attainable at all with the varied types of special construction.
  • the lubrication supplying device for the surface of the ring engaged by the traveller is formed of lubricant supply lines and grooves for the ring. It is also possible, in accordance with the invention, to make the ring of a porous material which has been found to be especially suitable for the use of ring travellers, the ring travellers being formed at least at the engaging surfaces thereof of plastic material.
  • a ring for ear-shaped travellers wherein the total height of the ring is at most 10 mm, and wherein the surfaces thereof engageable with the traveller continuously merge into the upper surface of the ring.
  • Such a ring for earshaped travellers differs from the heretofore known rings for ear-shaped travellers by the fact that it has a relatively small total height and by the fact that no recess is provided therein for passage of yarn or thread therethrough.
  • a thread guiding device wherein the surface of the ring engaging; the traveller merges with the upper surface of the ring with an initial radius of curvature that is from one-fifth t0 one-tenth the height of the ring.
  • a holder for the ring whose height or thickness is smaller than one-third the height of the ring.
  • every means which serves for holding the ring between both ends of the traveller i.e., also, for example, besides the well-known ring crosspieces also, for example, the ring bank, if the ring is directly inserted into the ring bank.
  • the ear-shaped ring traveller is provided with an upper large and a lower small hook-shaped portion, respectively, which together surround the ring, the inner height of the traveller being 12 mm at maximum and the large hookshaped portion thereof being curved in one direction.
  • the ear-shaped ring traveller of the invention distinguishes from heretofore known earshaped ring travellers, on the one hand, by its relatively small size and, on the other hand, by the omission of a pocket therein, which affords passage therethrough of yarn or thread in the heretofore known ear-shaped ring travellers.
  • the large hook-shaped portion of the traveller has a length which-is substantially double that of the smaller hook-shaped portion. Moreover, it is another feature of the invention to construct the larger hook-shaped portion with an inner width which is at least 1.2 times the inner width of the smaller hookshaped portion. Furthermore, in accordance with an added feature of the invention, the spacing of the ends of the ear-shaped ring traveller corresponds substantially to half the inner height of the traveller.
  • the produced fiber fly and dust which is unnecesaary for lubrication can escape without hindrance.
  • these fibers and dust particles accumulate either in the recess of the ring or in the pocket of the ring traveller because the engagement between the ring and the ring traveller at the upper surface of the ring prevents escape thereof to the outside.
  • special dust removing means are provided at the revolving path of the ring traveller in the heretofore known devices, which is no longer necessary for a device according to the invention of the instant application.
  • FIG. 1 is a sectional view of a thread guiding device according to the invention showing a ring accompanied by a traveller, only part of the ring being illustrated, the unillustrated part thereof being a mirror image of the illustrated part;
  • FIG. 2 is a view of the ring traveller reduced in size as seen from the inside of the ring;
  • FIG. 3 is a view similar to FIG. 1 of another embodiment of a thread guiding device provided with a lubricant supplying device.
  • FIG. 1 there is shown a thread guiding device constructed in accordance with the invention, which is formed of a ring 1 that is secured in a ring holder or ring bank 2.
  • An ear-shaped ring traveller 3 is rotatably mounted on the ring 1 and serves for guiding a yarn or thread F in a nonillustrated spinning cop.
  • the ring 1 and the ear-shaped ring traveller 3 are of such dimensions that, in the course of the travel of the ring traveller 3, it engages the ring 1 only at the inner surface or side 1a and at the lower surface or side 1b thereof and not, however, as was conventional heretofore at the upper surface of side 10 thereof, so that between the upper side 10 of the ring and the ear-shaped ring traveller 3, adequate space remains for affording passage therethrough of the yarn or thread F.
  • the inner height 31 of the traveller is considerably greater than the height 1 l of the ring 1. Since the upper surface 1c of the ring 1 however can also have a different construction within the scope of the invention of the present application, for example in accordance with the illustrated dotted line shown in FIG. 1, small differences between the inner height 31 of the traveller 3 and the ring height 11a can occur. In a similar manner, this relationship can be changed by providing the upper hook-shaped portion 3b of the traveller with a different shape, for example, corresponding to the dotted line so that the traveller is provided with an inner height 31a.
  • the inner height of the traveller be generally at least 15 percent'greater than the ring height in order to permit occurring fiber fly and dust, even for conventional, inclined positions of the traveller, to pass freely to the outside so that no blockage can occur.
  • This force Z minus B proloses a downwardly directed component C having a vertical portion C which extends opposite in direction to the upwardly directed tensile component A of the thread.
  • an inclination of from 4 14 preferably is selected for the angle of inclination B (F IG. 2), especially desirable friction relationships of the ring traveller 3 to the ring 1 result therefrom, because the smaller lower hook-shaped portion 3a of the ring traveller 3 engages the bottom surface lb of the ring only lightly. Consequently, the wear at this location is also reduced quite markedly.
  • the aforedescribed thread guiding device for ring spinning and ring twisting frames formed of a ring and an ear-shaped ring traveller, also produces a very special effect.
  • a downwardly narrowing wedge-shaped volume 4 filled with lubrication which permits penetration into the same of the wool, grease or lanolin, avivage, fiber particles or the like given off by the thread passing through the space between the ring and the'traveller can penetrate between the ring and the ring traveller. It is known that the ring traveller 3, as it is being pulled by the thread F, assumes the inclined position indicated by the angle B shown in FIG.
  • the angle [3, as is generally known, increases with an increase in the friction between the ring and the traveller.
  • a largerangle [3 indicates however that the spacing between the upper surface lc of the ring and the inner surface of the upper large hookshaped portion 3b of the traveller becomes smaller.
  • the improved lubrication produces raising of the ring traveller 3, i.e., a reduction in the size of the angle B.
  • the illustrated ring 1 exhibits marked differences as compared to the heretofore known rings for ear-shaped travellers.
  • the total height 11 of the ring 1 should not be more than 10 mm, i.e., the ring 1 of the instant application is considerably lower in height than the heretofore known rings for ear-shaped travellers. The reason therefor is that the fiber grease between the traveler and the ring is no longer adequate when this limit is markedly exceeded.
  • the height of the ring is sufficient if the thread guiding device according to the invention is employed, for example, for
  • the ring 1 does not have any recess for the passage therethrough of the thread or yarn F. Instead of such a recess, the traveller engagement surface 1a merges into the upper surface lb of the ring with a starting radius which is one-fifth to one-fifteenth, preferably one-tenth of the ring height.
  • This radius r in combination with a suitably shaped ring traveller permits the formation of an especially advantageous wedge-shaped volume 4 filled with lubricant.
  • a further feature of the new ring of the invention is that the height 12 of the ring crosspiece 1d is smaller than one-third of the ring height 1 1. Due to this feature it is assured that even for an advantageous coincidence of several limiting conditions a reliable guidance of the ear-shaped ring traveller 1, which does not engage the ring at the upper surface thereof, both during the starting up phase as well as during the regular travelling phase of the traveller. If the ring is provided with another kind of holder instead of a cross-piece M, for example, it is inserted directly into the ring bank, the given relationships are equally applicable as long as it is concerned with the region swept by the ends of the ring traveller 3.
  • the novel ear-shaped ring traveller of the embodiment illustrated in FIG. 1, which is used in a thread guiding device according to the invention, has a traveller with an inner height 31 of 12 mm maximum.
  • the upper large hook-shaped portion 3b is curved only in one direction and the ring traveller thus has no pocket for passage of thread F therethrough.
  • an ear-shaped ring traveller without a pocket for the passage of thread therethrough is employed for the first time, the inner height thereof being less than 12 mm.
  • the length 36 of the large hookshaped portion 3b is substantially twice as large as the length 32 of the small hook-shaped portion 3a. The ratio of these two hook-shaped lengths can naturally deviate by about percent from the given value in accordance with the form of the rlnG and the ring traveller.
  • the inner width 34 of the large hook-shaped portion be at least 1.2 times the inner width 34 of the small hook-shaped portion 3a. It is furthermore advantageous if the spacing 35 between the traveller ends comes substantially to half the inner height of the traveller. Finally it is also clearly noted with respect to the illustrated embodiment of FIG. 1 that both the large hook-shaped end 3b as well as the small hook-shaped end 30 are directed outwardly so that incident fiber fly, dust and the like can be readily ejected.
  • FIG. 3 there is shown an additional embodiment constructed in accordance with the invention of the instant application.
  • the ring 1 is formed of porous material, for example, sintered steel, the supply of lubricant being effected through lubricant supplying line 8 as well as the lubricant storage 9.
  • the engagement surface at the ring 1' of the traveller is formed of plastic material 3c.
  • the steel portion is completely surrounded by the plstic material only in the region of the lower traveller arc or bend 3a, whereby the steel portion over the long region can avoid contact and can have a greater elastic deformability.
  • This relatively higher elastic deformability is of special significance for a ring traveller according to the invention of the instant application in that it permits a relatively easy mounting of the traveller on the ring.
  • a thread guiding device for ring spinning and ring twisting frames which combines the advantageous thread passage way of the C-shaped traveller with the advantageous large engagement surface of the ear-shape traveller without having to take into consideration the disadvantages of both types of travellers.
  • the advantageous effects of the invention are not limited to special materials for the ring or the ring traveller. It is completely possible to manufacture the ring as well as the ring traveller either of steel or a plastic material or both of steel and plastic such as, for example, the travel surface of the ring traveller on the ring can be made of plastic material such as a long-chain synthetic polymeric amide known under the trade name of nylon or the like, and the zone through which the thread passes can be formed of steel.
