Definitions

  • the present invention relates to a method and apparatus for handling a plurality of threads or yarns'fed continuously from a suitable source, propelled through aftertreating baths and thence through drying orsla'shing equipment to a point of collection. More particularly this invention relates to spinning-in a group of threads that are withdrawn from the spin-bath bymeans of a common draw-01f roller and passed in the'form of a warpto aftertreatments. This type of continuous spinning. is known as the Heim system and is disclosed inter alia in U. S. Patents Nos. 2,334,325 and 2,566,438!
  • the invention is also concerned with threading-in one or more threads which may become broken during the spinning cycle at any point in advance of the drier or slasher because after the warp of'thrcads has been aftertreated, it is necessary that they be passed through' some form of drier such as a slasher where they are stretched in a wet condition and drieduHder tension.
  • the thread-in party of this invention is applicableto several types of continuous spinningsystems. in which a plurality of generally parallel running ends are to be dried on common rollers that are long enough to accom modate thethreads but cannot be stopped to thread-up one or more broken threads.
  • Another such system is disclosed in application Serial No. 122,560, now Patent 2,725,276, assigned to the. same assignee as the present application. 'Inthat application, the threads are aftertreated individually in a series of tubes but uponemerging from the last tubes are thereafter passed through the drying rollersin a manner similar to that in the Heim system.
  • Figure 1 is a perspective View of a portion of the Heim machine showing the common draw-off roller for withdrawing a warp of threads from the spin-bath, a temcollecting devices and cutting knife of the present invention being shown;
  • Figure 3 is a perspective view of the collection appav ratus and the associateidtemporary collectingdevices
  • FIG 4 illustrates with the apparatus of Figure 2 the early steps of threading-in according to the present invention
  • Figure 5 illustrates with the apparatus of Figure 3 the later steps in the threading in according to the present invention
  • v I Figure 6 is a detailed perspective view to an enlarged scale of the temporary collecting device and associated thread guides, knife guard and cutting knife arranged according tov the, present invention.
  • the present invention contemplatesa simplified procedure which eliminates considerable timeand waste. 'Before the spinning-in step is initiated, agpackage of finished yarn' 10 is mounted in a together in the form of a warp and .are passed between heated drying rollersthat define therebetween a tortuous passage-way. Since the yarnsare continuously delivered and hence must be continuously drawn by the drying rollers, it is not possible to stop the drawing action of the drying rollers in the event of yarn breakage between the feeding rollers andthe drying rollers.
  • the apparatus there 'shown comprises a rod 15 which extends parallel to the rollers 11 and 12 about midway therebetween, a housing 16 mounted to slide on the rod 15, a'compressedair supply conduit 17 leading to one end ofthe housing, a withdrawal conduit 18 leadingfrom the other end of the housing and thread guides 19 and 20 mounted on the conduits 17 and 18 I respectively.
  • the housing 16 is a suction type thread through the conduit 18.
  • the apparatus heretofore described is used to assist in threading-in aftertreating apparatus of the type depicted in Figure 1.
  • the leader 14 is established as described above and the operator then takes one of the freshly spun yarns, draws it over the roller 11 and drops it into the notch 21 of the housing 16 of the suction device.
  • the compressed air flowing in the conduit 17, passes to conduit 18 where it entrains the thread and delivers it to a waste receptacle, not shown.
  • the operator after the thread is entrained, leads the freshly spun yarn over the guide 20 and knife guard 23 while the leader 14 is passed over the guide 20, guard 23, and under the guide 19, see Figure 6.
  • the operator now ties a loop over the freshly spun thread and the leader at point 24.
  • the leader draws the freshly spun thread over the knife 22 cutting it betweenthe knot and the part passing into the notch 21.
  • the leader then draws the running end of freshly spun yarn through the aftertreatrnent baths 13 and through the drier to a temporary collecting device associated with a winding machine in the manner shown and described in copending application Serial No. 244,114, filed August 29, 1951, now U. S. Patent 2,706,089.
  • leader 14 it may be desirable to tie several freshly spun threads at 24 to leader 14 in which case these several threads are first dropped into notch 21 where they are entrained by the air flowing through conduit 18. After the threads are cut by knife 22, the leader 14 carries them through the drier to a temporary collecting device in the manner shown and described in application Serial No. 244,114, filed August 29, 1951. a
  • the yarn path over the guide 20 and guard 23 but under the guide 19 is such as to bypass the knife 22 whereas the yarn path under the guard 23 and under the guide 19 causes the yarn to be cut;
  • the leader may be broken at X as shown in Figure 1 and the running part of it collected as waste.
  • device may be positioned to several threads running in various positions between the rollers 11 and 12, the rod 15 is of the same length as the rollers and the housing is arranged to slide on the rod and to be held in any position of adjustment by a thumb screw indicated in Figure 6 by the numeral 16a.
  • the numerals 25a, 25b, 25c, 25d, 252, and 25 represent six wet rayon yarns emanating from a continuous spinning source, for example, of the type shown in Figure l, and delivered by a roller 26 to a series of drying rollers 27, 28, 29, 30 and 31.
  • the yarns issuing from the last liquid treatment of the continuous spinning system are arranged in parallel relationship and are passed over roller 26 in the form of a web comprised of a group of threads or yarns running in generally parallel mutually spaced relationship.
  • These yarns are drawn by the drying rollers 27, 28, 29, 30 and 31, all of which are heated by conventional means, not shown, and the yarns in the tortuous passageway around and between the rollers are dried.
  • the yarns then continue to run in parallel relationship to individual collection devices which, in the present instance, are a series of cone winding devices designated by reference numerals 32a, 32b, 32c, 32d, 32e and 32 In the normal threading-in of the apparatus of the In order that the suction type shown in application Serial No. 122,560, now U. S. f
  • Patent 2,725,276, threads 25a to 25 inclusive are passed through rollers 27 to 31, inclusive, in themanner shown in Figure 2, and are led each to a temporary collecting device of a suction type designated in Figure 3 by the reference numerals 33a, 33b, 33c, 330., 33c and 33,.
  • the operator individually pulls a loop between the respective collecting devices and the roller 31 and passes the loop over the various guides of the respective coning machine, starts the machine and cuts the thread running between the suction device and the coning machine.
  • This operation is not described in detail in this application since it forms the subject matter of my copending application Serial No. 244,114, filed August 29, 1951. Operation continues until the cones on the coning machine require to be doifed, at which time dofiing is effected in the manner described in the copending application mentioned above.
  • the thread 25b breaks somewhere in its run between the roller'26 and the drying roller 27. Since the drying rollers actually propel all of the threads, the end which is being drawn will pass on through the rollers 27 to 31, inclusive, and on to the coning machine 32b. The coning machine, through its own drop wire mechanism, will automatically stop when the last of the thread is wound up. On the other hand, the running end of the thread 25b which is issuing from the roller 26 can shortly become an operational hazard unless prompt steps are taken. According to this invention, the running end 25b is led by an operator to the suction device 16 so that some tension is maintained on the running part of the thread 25b and tangles are avoided.
  • Thread 25a being unbroken continues to be drawn by the thread rollers 27 to 31, inclusive, and the suction device 33a. Hence the thread 25b is eventually drawn through the drying rollers and into the suction device 33a (see Figure 5).
  • the procedures and apparatuses described in application Serial No. 244,144, filed August 29, 1951 are employed to restore normal operation.
  • the operator breaks the thread 25b and throws the running end into the suction device 33b so that both of threads 25a and 25b are collected separately. Thereafter, the coning machines may be threaded up to begin the next winding period.
  • yarn and thread have been used interchangeably, since their more specific meanings have no bearing on the operation or utility of the present invention which is equally suitable to twisted or untwisted strandular material regardless of its chemical composition.
