Definitions

  • Waste yarn spools are placed on the bobbin spindle, and when the upper Waste yarn spool is full, the waste yarn is automatically wound on the lower spool until the next time that the bobbin is removed, at which time the waste yarn spools are replaced.
  • This invention relates to methods of and an apparatus for removing the starting waste yarn occurring during a yarn twisting operation.
  • the process of this invention is applicable to ring twisters and false twist machines as well. Twisting, drawing, and similar operations on yarn are conducted with such machines and yarn is wound onto bobbins. During threading operations and during the commencement or termination of winding operations, the occurrence of waste yarn is inevitable. Since such inferior yarn is not desired to be wound onto the bobbin, it is wound on another package for removal.
  • the present invention is related to such method and an apparatus for practising such process.
  • the primary object of the present invention which has been devised for the purpose of eliminating such a loss of time and labor is to continuously conduct operations without cutting the running yarn on the yarn machine between the bobbin and waste yarn spool and to eliminate the disadvatage of the conventional process.
  • the waste yarn is Wound on one waste yarn spool. If such a spool becomes full, it must be replaced.
  • a plurality of waste yarn spools are provided one upon another detachably on the same axis.
  • This invention enables a full waste yarn spool to be replaced without cutting the as-wound yarn on the yarn machine, by providing detachably multistage waste yarn spools and introducing the waste yarn to the lower spool when the upper spool has become full, during the time of which the upper full spool is replaced and later winding of the waste yarn is onto the upper new empty spool.
  • the object of the present invention is to substantially eliminate time and labor which conventional operations would otherwise require by replacing a full waste yarn spool without cutting the as-wound yarn running on the yarn machine.
  • Another object of this invention is to lessen the waste of yarn by minimizing the number of rethreading operations and maintaining the amount of waste yarn to a minimum.
  • FIG. 1 is a diagrammatic front sectional view of an apparatus for performing the removal of inconsistent, waste yarn, and
  • FIG. 2 is a perspective view of a waste yarn spool.
  • This invention contains two embodiments relating to each other. Referring to the drawings, the first embodiment is explained below.
  • yarn 1 which has left the last rollers (not shown) of the yarn machine is wound onto bobbin 6 after it is passed through guide 2 and traveler 4 set on ring 3, said bobbin 6 being detachably mounted on spindle 5 positioned in the center.
  • Upper waste yarn spool 8 and lower waste yarn spool 9 are detachably secured on the lower part 7 of said spindle '6.
  • the yarn machine is at a standstill with the yarn donned and consequently, operation may be resumed only by starting the apparatus, without any rethreading operations.
  • the above operations are thus repeated several times until upper spool 8 becomes full of waste yarn.
  • ring 3 is moved to the lower spool 9 position (position shown with dotted lines in FIG. 1) and the waste yarn occurring at the time of termination of the winding-operation is Wound on lower spool 9 when the yarn machine is stopped.
  • the full upper waste spool can be replaced by an empty one without cutting yarn on the yarn machine.
  • the method in this invention is to replace the upper waste yarn spool many times without cutting the yarn running on the machine and only with the starting donning.
  • the present method is extremely efiicient and results in much less waste yarn.
  • the number of continuous doffings with two spools amounts to 8 to 10 times as many as that with one spool.
  • a single embodiment with 2 spools has been described, but the scope of the invention includes 3 spools or more.
  • FIG. 2 shows a waste yarn spool to be used.
  • Waste yarn spools 8 and 9 have flanges 10 and 11, and 12 and 13, respectively, and adjacent flanges 11 and 12 of spools 8 and 9 have notches 14. Without notch 14, the transfer' of the yarn from each spool to the other would be impossible. After the upper spool has become full, the yarn is to be transferred to the lower spool, but the yarn movement would be prevented by flanges 11 and 12, even if ring 3 is lowered to the lower spool.
  • the number of notches may be plural.
  • the improvement for replacing a full waste spool with an empty waste spool without cutting the running yarn on said machine which comprises installing multistage waste spools detachably around the bottom of a spindle of said bobbin, transferring said waste yarn to the lower of said waste spools when the upper of said waste spools has been wound fully, replacing said full upper waste spool by an empty waste spool, and returning the waste yarn to the upper empty spool.
  • an apparatus for removing waste yarn from uniform yarn in said yarn machine comprising multistage waste spools detachably mounted around the bottom of said spindle, said multistage waste spools having upper and lower flanges, respectively, and being separable from each other.
