Definitions

  • This invention relates to double twist spindles forimparting a twist to yarn and has for an ob- .iect to provide a high speed double twist spindle of novel and improved construction which is interchangeable with the usual spindles on standard twisting frames and which is particularly adapted for use with large yarn packages.
  • Another object is to provide a device of the above type having improved means for threading and starting and capable of smooth and uniform operation.
  • the invention is particularly advantageous in the twisting of continuous silk or rayon, and more particularly of fine yarns. but it is likewise applicable to twisting or increasing the twist of any other yarn.
  • the yarn is unwound from a stationary spool onto a hollow spindle revolving at high speed, and forms one loop as it unwinds and passes through the central opening of the spindle. whereupon it emerges below the spool through a lateral aperture and forms a second loop outside the first, passing towards a guide situated at a point on the axis of rotation of the spindle.
  • Various means have previously been proposed for holding the spool stationary on the spindle, such arrangements depending on mechanical, electrical or electromagnetic means.
  • the spindle is fitted at the point opposite the outlet aperture, with a conical plate reinforced by an exterior locking ring and having several channels, e. g. three, diverging within the conical body and facilitating the introduction of a needle to insert the thread at the starting.
  • the winding is enclosed in a stationary transparent bell shaped cap separating the two loops, particularly during starting operations.
  • Still another feature consists in the'mounting of the spool on an intermediate cup supported on a housing mounted on roller bearings upon the upper part of the spindle with elastic buffers establishing a connection between the cup and the housing.
  • Fig. l is a side elevation of a double twist spindle embodyins the present invention.
  • Fig. 2 is an enlarged vertical section taken substantially on the line 22 of Fig. 4 :1
  • Figs. 3, 4, 5 and 6 are horizontal sections taken on the lines 2-2, 4-4, 5-5 and 6-8 respectively of Fig. 2;
  • Fig. 7 is an enlarged detail sectional view through one of the braking members by which the rotation of the spindle is stopped.
  • the spindle including a shaft II, the lower portion of which has a conical end il resting on a special thrust-bearing l2 in a cup ii on a bracket
  • the vertical position of the bearing I2 is adjusted by means of shim IS.
  • the cup l3 constitutes an oil sump.
  • a fixed banle it prevents creeping of oil along the shaft.
  • the shaft It is centered and supported by a roller-bearing I! in a boss ll of the bracket H.
  • the upper portion of the shaft in is formed with an axial bore 20' enlarged'at either end and registering at the bottom with symmetrically inclined openings 2
  • is hot-forced on the shaft [ll above the bearing H.
  • a circular plastic disc 25 is mounted on the sleeve 22 and has three inclined holes 28 positioned 120 apart registering with the channels 23 whose center lines are generatrices of a cone. Small resistant tubular inserts 21 are placed in these holes 26 to avoid mechanical degradation of the yarn by contact with the plastic disc.
  • the disc 25 is reinforced by a steel ring 28 coated with hard chrome.
  • This specially shaped ring is likewise pierced with three holes at 120, matching those in the disc. It has a peripheral groove 29 so shaped that the yarn having one of three holes can wind helically on the ring and make one or more turns in the groove before separating from the ring and forming the lower part of the loop.
  • the ring has a head 30 on its upper surface to match a groove 3
  • a cylindrical sleeve 25 of plastic or non-magnetic metal is iournalled on'anti-friction bearings 36 and 21 on the free upper end of the shaft 66 II with a lower shoulder 3
  • a plastic cup I! is mounted on the sleeve 35 by two semi-flexible rubber buffers 4
  • the upper portion'of this cup 32 carries the twist-halting arrangement, consisting of a steel ball 43' in a '60 cone ll concentric with the bore of the shaft It.
  • the cone 44 is also of steel. but coated with hard chrome.
  • This cone II is held in place by a nut I! screwed on the cup 32, and having a depending skirt 46 to sup-- port a metal cone 41 carrying the yarn package 40.
  • the hemispherical upper end of the cone 41 is provided with a rolled bead 50 having a high polish and applying a slight tension to the yarn passing thereon, thus avoiding untwisted filaments.
  • the general form of the cone 41 is such as to facilitate passage of the needle carrying the yarn.
  • 32 is in the form of a truncated cone and has 'two rows of three rectangular openings 52 and is spaced 120 apart and adapted to receive the poles I and II of the magnetic holding means for the spool.
  • the lower part of the cup carries a smallbircular trough 56 to catch any lubricant that may leak from the bearing 30.
  • a transparent plastic bell is seated on a flange ll of the cup 31, encloses the spindle and prevents contact, during starting, between the unwound yam and the yarn forming the balloon.
  • the outer fitting 12 in the form of an inverted cup, is a piece of pressure-cast nonmagnetic metal or plastic. It is centered and attached by screws 13 to the upper part of the bracket ll.
  • the clearance required for the passage of yarn, may vary between 2 and 3 mm.
  • the fitting 12 has a wide cut-out 15 opening above into a slit 16. These openings permit access to the revolving disc, and allow for initial needlingin of the yarn.
  • the closure consists of a pressed sheet-metal shutter ll enveloping the lower part of the outer fitting l2 and rotatable about the latter. It is centered by a groove 19a in a collar 19 of the bracket M. It has a cut-out of the same shape as that in the outer fitting. By simply tuming this part, the opening in the fitting may be opened or closed at, will. Braking is accomplished by three small pins 80, one of which is shown enlarged in Fig. 7, 120 apart, passing through the outer fitting and raised by three As they rise, three pins slightly lift the disc A and hold it. They are retained by three leaf springs 82 when the rotation of the shutter is reversed.
  • the yarn then passes down the bore 20 of the shaft l0, through one of the holes 24 in the disc 28 and in one or more turns around the chromed steel ring 20, the number of turns depending on the tension applied by the preceding elements.
  • the yarn then balloons out centrifugally and passes through the guide 00 to the winding spool.
  • the spindle for much larger windings up to 2000 grams, is similar indesign, but is of course larger and carries larger bearings, such as ball bearings where necessary in view of the greater weight.
  • the device described has numerous advantages.
  • the permanent magnet used does not involve the complications of electromagnetic or mechanical systems, and imposes no speed limitation.
  • the ball brake affords a simple and accurate maintenance of uniform tension, and
  • a double twist spindle for a yarn twister comprising a vertical shaft rotatably mounted in upper and lower: bearings and projecting upage support journalled on said shaft, above said upper bearinaan annular outer member disposed around said support, magnetic members carried by said outer member and by said support to hold said support against rotation, a rotatable sleeve on said outer member, openings in said last sleeve and in said 01 tax member to be aligned for threading the spindle, a brake carried by said outer member are-2:,ed to stop said shaft, and means actuated by said last sleeve in responseto turning thereof to set'and release said brake, said shaft having an axial bore extending from its upper end to receive yarn from saidpackage, a disc fixed to said shaft below s .d package support having a plurality of symmetrical, upwardly inclined holes communicating with said bore and terminating in the outer periphery'of said disc and adapted to paw a flexible wire for threading the spindle.
  • a spindle as set forth in claim 1, in which said brake comprises a set of pins carried by said outer member to engage said disc and said last sleeve carries inclined su'rfaces adapted to raise said pins into braking contact with said disc.
