Definitions

  • the present invention relates to a winding tube used in a yam winding device of a false twisting machine, a plurality of packages formed on the winding tube, and a method for producing the plurality of the packages.
  • a yam winding device described in the Patent Literature 1 winds a plurality of yarns in a false twisting machine.
  • One winding tube is held rotatably by a cradle.
  • the plurality of the supplied yarns may not be doubled and wound respectively onto parts of the winding tube separated from each other, thereby forming a plurality of packages.
  • the winding tube on which two packages are formed in the yam winding device is cut at a substantially center in the lengthwise direction so as to make two independent packages, and the packages are used in a post process (see the paragraph 0046 of the Patent Literature 1).
  • the formation of the plurality of the packages on the one winding tube advantageously improves the productivity of the packages.
  • the unwinding characteristic of the yam is also improved advantageously.
  • the reason why the unwinding characteristic of each package is improved is that the winding width of each package becomes small by forming the plurality of the packages on the one winding tube. For example, when one package is formed on one winding tube, the winding width is 250mm and the maximum package weight is 6kg, whereby the winding width is large. When the winding width is large, the unwinding tension is large and the yam is breakable.
  • the winding width is 110mm and the maximum package weight is 2kg, whereby the winding width of each package is small.
  • the winding width is small, the unwinding tension is small and the yam is not breakable easily.
  • the yam amount of each of the individual packages is small. Then, when the packages are used in the post process, the number of times of exchange of the packages is increased, whereby the operation efficiency of the post process is reduced.
  • a yam winding start end is inserted into a harness hole formed in the winding tube so as to fix the yam winding start end to the winding tube, and subsequently the formation of the package is started.
  • the prior preparation work before forming the package is premised on manual labor of an operator and requires a long time. Accordingly, for example, when the package which is a full roll is doffed and exchanged with a new winding tube, it is considerable to be necessary to stop supply of the yam temporarily and perform the prior preparation work though it is not clearly shown in the Patent Literature 2. When the prior preparation work is finished and the new winding tube is attached, the supply of the yam is resumed and the formation of the package is resumed.
  • the Patent Literature 3 does not disclose the prior preparation work before forming the package.
  • the present invention is provided for solving the above problem.
  • the first purpose of the present invention is to provide a winding tube in which a yam to be a tail yam can be secured beforehand at winding start of a package in the case in which the plurality of the packages are formed on the one winding tube.
  • the second purpose of the present invention is to provide a package which has enough large yarn amount and good unwinding characteristic by connecting yarns of a plurality of packages formed on a winding tube, wherein the package can be handled easily because the number of the winding tube is one.
  • the third purpose of the present invention is to provide a method for producing such the package.
  • a winding tube of the first invention is held by one cradle provided in a yam winding device of a false twisting machine. Onto the winding tube, a plurality of supplied yarns are wound so as to form a plurality of packages.
  • a capture part is provided which captures a yarn winding start end of at least one of the pair of the packages.
  • a winding tube of the second invention is subject to the winding tube of the first invention.
  • the capture part is a groove formed in an outer peripheral surface of the winding tube substantially along a peripheral direction of the winding tube.
  • a winding tube of the third invention is subject to the winding tube of the first or second invention.
  • the false twisting machine includes a yam supply part having a plurality of yam supply packages and feeding out the plurality of the yarns and a false-twisting part performing false-twisting on the plurality of the yarns fed out from the yam supply part.
  • a winding tube of the fourth invention is subject to the winding tube of the first to third inventions.
  • the plurality of the supplied yarns are two yarns.
  • the plurality of the packages are a first package and a second package.
  • the capture part is a second capture part which is provided at a position between the first package and the second package and captures a yarn winding start end of the second package.
  • the first package and the second package are formed by winding respectively the two yarns.
  • a package of the fifth invention is subject to a plurality of packages formed by winding a plurality of yarns onto the winding tube of the first to third inventions.
  • a tail yarn is formed in the one package between the pair of the packages whose yarn winding start end is captured by the capture part, and the tail yarn is connected to a yarn winding finish end of the other package.
  • a package of the sixth invention is subject to a plurality of packages formed by winding two yarns onto the winding tube of the fourth invention.
  • a second tail yarn is formed in the second package among the first package and the second package whose yarn winding start end is captured by the second capture part, and the second tail yam is connected to a yarn winding finish end of the first package.
  • a method for producing a package of the seventh invention is subject to a method for producing the plurality of the packages by winding a plurality of yarns onto the winding tube of the first to third inventions, comprising a first process in which a yarn winding start end of each of the yarns forming the plurality of the packages is captured by the capture part or between the winding tube and the cradle, a second process in which bunch winding of the plurality of the yarns is performed respectively, a third process in which the packages are formed respectively by the plurality of the yarns, a fourth process in which the bunch winding yarns of the packages except for the package the most close to a first end of the winding tube among the plurality of the packages formed in the third process are processed so as to form tail yarns, and a fifth process in which the tail yarn of the package at a side of a second end of the winding tube between the pair of the adjacent packages of the plurality of the packages is bonded and connected to a yarn winding finish end of the package at the side of the first
  • a method for producing a package of the eighth invention is subject to a method for producing the plurality of the packages in which the first package and the second package are formed by winding two yarns onto the winding tube of the fourth invention, comprising an eleventh process in which a yam winding start end of the yam forming the first package is captured by a first capture part formed between the winding tube and the cradle and a yam winding start end of the yarn forming the second package is captured by the second capture part, a twelfth process in which bunch winding of the yam forming the first package and the yam forming the second package is performed respectively, a thirteenth process in which the first package and the second package are formed by the two yarns, a fourteenth process in which the bunch winding yam of the second package is processed so as to form a tail yam, and a fifteenth process in which the tail yam of the second package is bonded and connected to a yam winding finish end of the first package.
