Definitions

  • the invention relates to a multiple twisting frame fitted with permanent magnets for locating the pots of the winding-off bobbins.
  • the invention consists of a multiple twisting frame, comprising a spindle bench, twist spindles together with associated pots mounted on said spindle bench, the walls of the said pots containing permanent magnets in diametrically opposed relationship, separators for the said spindles, each separator being mounted on the said spindle bench between adjacent pots, the said separators carrying a permanent magnet positioned therein to act on the permanent magnets in the walls of adjacent pots.
  • the separator may, if required, carry connecting means for balloon limiters, e.g. holders therefor, in which instance the connecting means, e.g. holders, are preferably located in the neighbourhood of the magnets in the pots.
  • the foot portions of neighbouring separators are preferably so designed that they form a cover for the belt and, if desired, inter-mediate members may be provided between each two foot portions, which may form part of the cover, and which also may contain control elements, for instance for the brakes of the spindles. Furthermore, the intermediate members may be hinged and thus arranged themselves to control the spindle brakes.
  • the permanent magnets which are interposed between each two spindles and which act in both directions first and foremost ensure that the magnetic forces will not impose unbalanced' loads on the spindle bearings.
  • the magnets form a row lengthwise of the machine and this chain of magnets in conjunction with their concave shape on each side provides a particularly reliable means for locating the individual pots, while permitting them to be spaced very closely together.
  • the magnets and their support means are located so that they do not obstruct any work that has to be done at the spindles. They also offer no opportunities for the accumulation of dirt or for the ballooning yarn to get caught and they require no special support means.
  • the pot will be retained in the correct position whichever way round it may have been inserted, in other words the pot will always point forwards to permit parts to be checked which can only be checked if the pots are always in the same unchanged position.
  • Magnetisation of the permanent magnets to form poles of alternately opposite polarities provides a particularly powerful retaining force permitting the gap widths between the separator and the pots to be of substantial width, a matter of imporance when balloon limiters are absent.
  • the permanent magnets are located at a mid-portion of the pot walls, e.g. about half way up the sides of the protective pots. This permits the winding-off bobbin to be mounted at a lower elevational level on the spindle axis, resulting in a compact form of construction in which the balloons are squat so that the draw-oif speed of very fine and delicate yarns can be increased.
  • FIGURE 1 is a fragmentary perspective view of part of a multiple twisting frame with spindles without balloon limiters
  • FIGURES la and 1b illustrate details of the arrangement according to FIGURE 1,
  • FIGURE 2 is a horizontal section of the arrangement according to FIGURE 1, and
  • FIGURE 3 is a perspective view of a portion of a multiple twisting frame with balloon limiters.
  • FIGURE 1 shows two such spindles 2.
  • FIGURES l and 3 only separators intervene between neighbouring spindles 2, balloon limiters not being provided in this instance.
  • the separators 3 according to the invention are formed with a foot portion 4 by means of which they are mounted on the spindle bench 1. Permanent magnets 6 of a shape illustrated in FIGURE 10 are inserted into each of the separators 3.
  • the permanent magnets may be simply inserted into the separators 3 as indicated in FIGURE 1.
  • the separators may be provided with special pockets formed as illustrated in section in FIGURE 2.
  • the pockets 7 completely contain the magnets 6 which fit flush into an opening 5 in each separator 3. Another particularly convenient way of accommodating the magnets is to encase them directly in the separator 3 if these are produced in the form of castings.
  • each magnet 6 is magnetised as indicated in FIGURE 2 with poles of opposite polarity on each of its magnetic-ally active sides. Naturally this does not preclude forming a single pole on each side.
  • Each magnet 6 exerts an effect on each side thereof, as will be readily understood for instance from FIGURE 2.
  • Each active side of the magnet co-operates with a magnet 8 in the protective pot 9 of the spindle.
  • Each pot 9 contains two magnets 8 on diametrically opposite sides.
  • the magnets are covered by a protecting ring 10.
  • the protecting ring which may consist preferably of aluminum or a light metal alloy, openings containing soft iron yokes 11 are provided where the magnets are located. Owing to the metal alloy, openings disposition of the magnets 8 the forces due to the pull of the magnets affecting the bearings of the protective pot 9 in the rotary part 12 of the spindle are balanced.
  • a form of magnetisation providing several poles of opposite polarity on each side permits the air gap S to be relatively wide, an advantage if twisting proceeds without a balloon limiter.
  • the magnets 6 and their co-operating magnets 8 are not formed with several poles of alternately opposite polarity as illustrated in FIGURE 2, but with only one pole, then the magnets will operate to retain the pot 9 in one particular position, irrespective of the position in which the pot is inserted. A particular side of the pot can then be made always to face forwards, permitting parts to be checked which require all the pots to face the same way to permit the check to be made. This is an advantage for instance when multistage yarn brakes are fitted, in the case of which the position of the brake is indicated by marks. The marks will then always be visible at the same place and no special manipulations thus needed.
  • FIGURE 1 illustrates double twist spindles 2 without balloon limiters
  • FIGURE 3 illustrates a spindle 2 fitted with a balloon limiter 13.
  • This balloon limiter 13 is provided with holders 14 for attaching the same to the separators 3, the arrangement being such that the holders 14 are insertable into corresponding fittings on the separators 3.
  • the brackets 14 are located roughly where the permanent magnets 6 are contained in the separators 3.
  • the foot portions 4 of the separators 3 form a protective cover for the belt, and the cover may be formed continuously by the provision of suitably shaped intermediate members permanently inserted between each of two neighbouring feet 4 or an intermediate member may be provided which, as indicated at 15, is hingeably openable by operation of hinge pins 16 and holes 17, which further allows for the insertion of the parts 15.
  • an intermediate member may be provided which, as indicated at 15, is hingeably openable by operation of hinge pins 16 and holes 17, which further allows for the insertion of the parts 15.
  • the magnets 6 which exert their effect in opposite directions are mounted about half way up the height of the spindles 2.
  • This arrangement has proved to be particularly useful because it permits the bobbin 18 to be lowered in its protective pot 9 down the spindle axis by the additional amount formerly needed for the accommodation of the magnets at the bottom of the protective pot in the conventional form of construction, thus providing the previously mentioned advantage of the invention, and which substantially Widens the range of applicability and efficiency of the spindles.
  • the magnets placed half way up the side of the pot 9 are located in the embodiment illustrated, in that region where the shape of the balloon formed by the yarn ensures that the yarn will not touch either the pot 9 or the magnets 6 on the outside.
  • the magnets 6 could be located in the separators 3 at some other level, in which case the co-operating magnets in the protective pots 9 would have to be placed at the same level.
  • a soft-iron pole piece may be placed in the separator instead of the permanent magnet as hereinbefore described.
  • soft-iron pole pieces may be placed in the pots instead of the permanent magnets as hereinbefore described.
  • a multiple twisting frame comprising a spindle bench, twist spindles together with associated pots mounted on said spindle bench, the walls of the said pots containing permanent magnets in diametrically opposed relationship; separators for the said spindles, each separator being mounted on the said spindle bench between adjacent pots, the said separators carrying a permanent magnet positioned therein to act on the permanent magnets in the walls of adjacent pots.
  • a multiple twisting frame as claimed in claim 1, comprising a plurality of pots containing permanent magnets positioned in a mid-portion of the walls thereof, the said permanent magnets being of such strength as to act in both directions to exert a balanced force on the spindle in each pot.
