Definitions

  • This invention relates to thread advancing reels and more particularly, to reels having peripheries formed of a plurality of bar members used in the processing of the thread and the like.
  • the filamentary material such as viscose rayon yarn, thread and the like
  • the filamentary material is withdrawn from a liquid bath by a take-up or withdrawing reel, and then it is led for further processing to subsequent reels or collecting or treating stations.
  • the thread Because of discontinuous peripheries of bar type reels the thread, during certain processing steps, is subject to barre affects which it is desirable to eliminate. There is a tendency toward barre in the initial Withdrawing period for along with the thread there is also withdrawn amounts of liquid from the bath that is carried onto the reel to disturb normal contact of the still tender thread with the bar members because of an intervening layer of liquid between the reel bar surfaces and irregular thread and bar contact.
  • the volume of withdrawn bath liquids is not objectionable since not too great a quantity of bath liquids adheres to the thread; and the excess can be wiped off prior to the take-up reel substantially without injury or alteration of subsequent desirable thread characteristics.
  • the withdrawn thread tends to carry greater quantities of bath liquids so that a wiping device is not desirable since it introduces drag, and it becomes ineffective; also the yarn only intermittently contacts the wiping device because of the increased adhering liquid to affect the thread characteristics, for instance, dyeing.
  • barre efiects tend to appear because of initial intermittent contact with the spaced hot bars of a drier reel.
  • the thread in its initial travel over a heated reel rests on heated spaced supports and the supported thread sections are first dried while the intervening unsupported lengths are dried later. This initial unequal drying tends, also, to affect thread dyeing characteristics.
  • Thread advancing deviceshaving peripheries of spaced interdigitating bars are advantageously utilized in the processing of thread since they comprise efiicient and unitary structures that occupy a minimum of space, and also, they are adapted to advantageous arrangements facilitating the processing of thread.
  • the spacing of thread contact areas of bar members provides for a discontinuous circular support which is disadvantageous in the aforesaid processing steps. Excess liquid will adhere to the unsupported thread section while other quantities are forced outwardly in the supported sections. Eventually, of course, the entire length of the thread in its travel will be subjected to support by the bar members but the initial intermittent contact generally affects the thread in a manner so as to form barre.
  • This invention advantageously provides for a modified reel of the Knebusch type, although it is not limited thereto, that is adapted as a processing reel, a take-up or withdrawing reel, and as a drier reel.
  • a withdrawing reel it will substantially immediately throw off the spin bath liquids that are carried onto its periphery by the widthdrawn thread and yet provide for sufficient thread travel control.
  • the reel is used, generally, without a previous thread wiping guide.
  • the periphery of the reel comprises a plurality of thread storing and advancing bar members having initial tapered portions at the thread takeup end, then normal thread contacting portions for the remainder of their lengths.
  • the taper of the bars provides for a minimum thread contacting area thus, a minimum liquid adhering.
  • Either one or both sets of bars forming a reel can be tapered.
  • the bar taper generally is desirable only for that portion of the reel that is sufficient to throw off the bath liquids or to precondition the thread by slowly heating it, and thereafter the bars can be of normal contacting areas; the return to a normal contacting area permits a better control of the yarn on a reel, particularly, if a liquid treatment is to be applied.
  • Figure 2 represents the withdrawing reel in front elevation
  • Figure 3 is a side elevation of thewithdrawing reel of Figure 2;
  • Figure 4 is a section in elevationof .the reelof Figure 3;
  • Figure 5 is a cross section .of Figure 3. taken along lines 5-5.
  • the thread It is led directly: totthe reel overwhich it is'advanced .rinapluralityof generally helical turns to a desirablewtake oif point on its periphery from whenceit-is led-to a subsequent heated reel I6 .whereonitmay-be dried.
  • a liquid treatment for instance. a washing 1 step, advantageously can be .appliedonthe far end ofthe take-up reel l5 if desired.
  • the thread can'be led from a reel to a subsequent reel -;until a desirable number of processing steps'are-performed to provide a product having desirable characteristics.
  • the bar members form rigid 'reel members, one reel member.2l being concentrictothereel shaft I! while the other is positioned about an eccentric whose axis is offsetiand 'askew to the reel shaft.
  • the ,eccentrically mounted reelmember 2Ia is adapted torotate freely about its support while the concentric reel member 2
  • the reel of Figures 3 and 4 generally comprises such an aforesaid arrangement.
  • are concentric to the reel shaft ll.
  • Bars 20 form the eccentrically positioned reel member 2 la that is attached by means of a ring 24 into which the bars merge, and which ring 24 is secured to a flange 25 by means of bolts Flange25, in turn, forms apart of sleeve 30.
  • the sleeve'30 is adapted to rotate about an eccentric (not shown) that is positioned about vlithe reel shaft l1. Since the eccentric is held staiii .tionary. it. generally forms part of a reel support- "ing structure such as the flange 3
  • the reel i5 is driven by means of the gear 33 mountedat substantially the shaft end to which it is secured in a suitable and desirable manner for instance by a set screw 34.
  • the tapered sections 22, 23 of the bar members I9, 20 arenarrowed toward the yarn'bearingsurfaces to areasadapted to provide sufficient threadsupport while still permitting a substantial control of the thread. Because of the taper the'bar members 19,-20 tend to minimize the liquid-adhering area Withthe result that they more readily fling off the bath liquids since a substantial portion of liquid supporting and adhering surface has been eliminated.
  • the direction of the taper also tends to morereadily throw off liquids.
  • Such a reel periphery thus provides a substantially fluid-free .threadfor the-remainder of thereel and fora subsequent processing treatment. Further thread and bar contacts are minimized by such a bar construction substantially eliminating undesirable effects on the thread.
  • both sets of bars 19, 20 aretapered in the direction of thereel periphery.
  • the tapered bar members facilitate such a removal yet their speedof rotation need not cited so as to depend on centrifugal forcesentirely.
  • reel speeds are not of such a rate so as to carry over unusual amounts of bath fluid then a reel having a single set of tapered bar members will generally eliminate the interfering quantities of bath fluids.
  • spinning speeds are increased,.however,. to rates that .tend to carry substantial quantities of a bath liquid on .to the reel,. then it is advantageous .to have all barstaperedsince liquids will be-then more readily discardedfromthe reels.
  • the taper of bars l9 andZO mayextend substantially throughout lengthor only for a portion.
  • the length of the taperis of course, dependent on the amount of fluid carried overfrom the bath, and on the speed of the reel.
  • the bar members l9, 20 are advantageously brought to a normal peripheral width .to. provide suflicient thread bearing areas for holding the treatment liquids.
  • the bar members l9, 20 are advantageously brought to a normal peripheral width .to. provide suflicient thread bearing areas for holding the treatment liquids.
  • the thread M is made. substantiallyxfree ofthe bath liquids by .theutime .the .treatmentsis applied.
  • "Since speeds that tend to throw ofi" treating liquids may be used a liquid treatment distributing and maintaining blanket 36 advantageously may be utilized while the distributing tube 35 applies the treatment liquid. A treatment thus may be applied, maintained, and spread over a predetermined yarn area.
  • the reel I6 is of generally the same construction except that is is heated by circulating a heating fluid such as steam. hot water, etc. through its interior in the manner disclosed in the Bergmann Patent 2,294,866.
  • the bar members are advantageously tapered as those of reel I 5.
  • Wet thread is supported on bar members having a minimum thread supporting area for a desired interval of time until the thread is predried and then progressively raised to the full bar temperature.
  • Whatever markings are made on the thread on the reduced area bar members they are minimized in length or size and spaced so that the dyeing qualities of the thread are hardly affected.
  • processing reels for steps other than drying are reduced from a width of one-fourth inch to a sixteenth, and dryer reels from a half-inch to a sixteenth.
  • a thread storing, thread advancing reel comprising two sets of interdigitating bar members cooperating in a manner so as to advance thread and the like in the form of a general helix, and both of said sets of bar members having reduced thread contacting areas for a portion of their lengths, and said reduced areas being at the initial thread take-up end of the reel.
  • a thread storing, thread advancing reel comprising, two sets of interdigitating bar members, one of said sets being positioned offset and askew to the other, said sets upon rotation cooperating in a manner so as to advance thread and the like in the form of a general helix, and both of said sets of bar members having reduced thread contacting areas for a portion of their lengths, and said reduced areas being at the initial thread take-up end of the reel.
