  • the yarn Yg formed by the doubling is, as shown in FIG. 3(a) , slacken in the part between the downstream-side second feed roller 8b and the third feed roller 9b, and the yarn Yg in this state is subjected to slacken thermal treatment by the secondary heater 17b and then conveyed to the third feed roller 9b.
  • the yarn Yg sent out from the third feed roller 9b passes through the yarn guide 30c and is wound onto a single take up tube 19A contacting and rotated by the rotating winding drum 23, while being traversed by the traverse guide 27a which is reciprocally moved in directions in parallel to the axis of the take up tube 19A by the reciprocal movement of the belt component 26, with the result that a single package P is formed.
  • the moving distance of the traverse guide 27b when the yarn Yg is wound onto a single take up tube 19A is longer than the moving distance of each of the traverse guides 27a and 27b when the yarns Ya and Yb are wound onto two take up tube 19B, respectively.
  • the bending angle of the yarn Yg at the yarn guide 30c is of the same degree as the bending angles of the yarns Ya and Yb at the yarn guides 30a and 30b in the case of the formation of two packages.
  • a part of the yarn Yg between the yarn guide 30c and the traverse guide 27a is threaded on a substantially cylindrical guide bar 70, and is smoothly bended.
  • the part of the yarn Yg threaded on the guide bar 70 moves on the smooth outer circumference of the guide bar 70 in the axial direction of the guide bar 70, when traversed by the traverse guide 27a. This prevents the yarn Yg bended at the guide bar 70 from being seriously damaged.
  • the doffing of the package P and the yarn threading onto an empty take up tube 19A are carried out when the package P is fully formed.
  • the yarn threading onto the take up tube 19A is carried out by the automatic yarn threading device 24a. That is to say, in the present embodiment, the automatic yarn threading device 24a is used for performing yarn threading of the yarn Ya onto the take up tube 19B to form two packages P and for performing yarn threading of the yarn Yg onto the take up tube 19A to form a single package P.
  • the yarn Yg traversed by the traverse guide 27a may not oppose yarn moving lever 62 depending on the position of the yarn Yg. For this reason, when the yarn moving lever 62 is swung while the yarn Yg does not oppose the yarn moving lever 62 as in the same manner as in FIG. 8 , the yarn Yg is not moved toward the suction mouth 51.
  • the traverse guide 27a is temporarily stopped when the yarn Yg is positioned to oppose the yarn moving lever 62, and the yarn moving lever 62 is swung in this state. Thereafter, the yarn Yg is sucked into the suction mouth 51 and then the operation of the traverse guide 27a is resumed. This makes it possible to certainly move the yarn Yg toward the suction mouth 51 when the yarn moving lever 62 is swung.
  • a range opposing the yarn moving lever 62 is equivalent to the guidable area of the present invention, whereas a range not opposing the yarn moving lever 62 is equivalent to the non-guidable area of the present invention.
  • a winding device 18, which is switchable between the formation of two packages P by winding supplied two yarns Ya and Yb onto respective take up tubes 19B and the formation of a single package P by winding a yarn Yg in which yarns Ya and Yb are doubled onto a take up tube 19A, includes two automatic yarn threading devices 24a and 24b. It is therefore possible to perform yarn threading onto two take up tubes 19B at the same timing, when two packages P are formed. With this, the winding of the yarns Ya and Yb onto respective two take up tubes 19B start at the same timing. This does not complicate the operation of the operator.
  • the winding device 18 of the present embodiment winds the yarns Ya and Yb onto two take up tubes 19B provided at a relatively short interval, it is impossible to widen the gap between the automatic yarn threading devices 24a and 24b in the axial directions of the take up tube 19B.
  • the yarn providing arm 53, the yarn supporting arm 54, and the yarn pressing arm 55 of each of the automatic yarn threading devices 24a and 24b are swung about the shaft 65 or 66 extending along the axial directions of the take up tube 19B, and hence the components above do not really move along the axial directions of the take up tube 19B. It is therefore possible to provide the automatic yarn threading devices 24a and 24b at a short interval with respect to the axial directions of the take up tube 19B.
  • the present embodiment is arranged so that the yarn supporting arm 54 extends, at its leading end, to be n parallel to the axial directions of the take up tube 19B, and the yarn pressing arm 55 and the yarn supporting arm 54 sandwich the yarn Ya (Yb) to cause the yarn Ya (Yb) to closely contact the outer circumference of the take up tube 19B.
  • the yarn pressing arm 55 is detached from the yarn supporting arm 54 and moved to the original position after the formation of the bunch winding B, the traversal of the yarn Ya (Yb) by the traverse guide 27a (27b) becomes possible and the winding of the yarn Ya (Yb) onto the take up tube 19B can be immediately resumed. This makes it possible to prevent the yarns Ya and Yb to be straight-wound onto the take up tubes 19B.
  • each of the automatic yarn threading devices 24a and 24b has a yarn moving mechanism 52, it is possible to provide the suction mouth 51 to be remote from the yarn Ya (Yb) being wound. As such, the degree of freedom in the arrangement of the suction mouth 51 is increased.
  • the yarn moving lever 62 opposes the yarn Ya (Yb) wherever the yarn Ya (Yb) locates in the traversal range of the traverse guide 27a (27b), the present invention is not limited to this arrangement.
  • the yarn moving lever may be shorter than the yarn moving lever 62 of the embodiment above and oppose the yarn Ya (Yb) only when the yarn Ya (Yb) is in a part (guidable area) of the traversal range of the traverse guide 27a (27b), and not oppose the yarn Ya (Yb) when the yarn Ya (Yb) is in other parts (non-guidable area).
  • the yarn moving lever 62 is swung after the traversal of the traverse guide 27a (27b) is temporarily stopped when the yarn Ya (Yb) is moved to the position of opposing the yarn moving lever, with the result that the yarn Ya (Yb) is guided to the suction mouth 51.
  • the yarn moving mechanism 52 may not include the yarn moving lever 62 and the yarn guide plate 63.
  • the yarn moving mechanism 52 may be another mechanism which is able to guide the yarn Ya, Yb, or Yg to the suction mouth 51.
  • the suction mouth 51 is deviated from the yarn Ya (Yb) traversed by the traverse guide 27a (27b), in the axial directions of the take up tube 19B, and at the time of the yarn threading the yarn Ya (Yb) is guided by the yarn moving mechanism 52 to a position where the suction mouth 51 is able to suck the yarn.
  • the present invention is not limited to this arrangement.
  • the yarn moving mechanism 52 may not be provided, and the suction mouth 51 may be positioned so that simply opening the suction port 51a causes the yarn Ya (Yb) traversed by the traverse guide 27a (27b) to be sucked. In this case, however, the suction mouth 51 must be positioned to be able to suck the traversed yarn Ya (Yb) but not to interfere the yarn Ya (Yb) when the yarn is wound.
  • the embodiment above is arranged so that the yarns Ya and Yb are positioned by the yarn providing arms 53 to cross the border between the corresponding take up tube 19B and the bobbin holder 22a and to cross the border between the corresponding take up tube 19B and the O-ring 43, respectively.
  • the present invention is not limited to this arrangement.
  • the yarns Ya and Yb may be positioned by the yarn providing arms 53 to be in parallel to the respective borders.
  • a mechanism for sliding the yarns Ya and Yb positioned by the yarn providing arms 53 toward the borders in the axial direction of the take up tubes 19B may be provided.
  • the parts of the yarns Ya and Yb closely contacting the outer circumferences of the take up tubes 19B are certainly captured by being sandwiched between the corresponding take up tube 19B and the bobbin holder 22a and between the corresponding take up tube 19B and the O-ring 43.
  • the embodiment above is arranged so that the yarn Ya is captured by being sandwiched between the corresponding take up tube 19B and the bobbin holder 22a whereas the yarn Yb is captured by being sandwiched between the corresponding take up tube 19B and the O-ring 43.
  • the yarn Ya may be captured by being sandwiched between the corresponding take up tube 19B and the bobbin holder 22a and the yarn Yb may be captured by being sandwiched between the take up tube 19B and the bobbin holder 22b.
  • both of the yarns Ya and Yb may be captured by being sandwiched between the corresponding take up tubes 19B and the O-rings 43, respectively.
  • the bunch windings B are formed at the opposite end portions of the two take up tubes 19B, the direction of winding of the yarn Ya (Yb) is opposite between the two take up tubes 19B.
  • the present invention is not limited to the arrangement in which the yarns Ya and Yb are captured by being sandwiched between the corresponding take up tubes 19B and the bobbin holders 22a and 22b or the O-ring 43.
  • the yarns Ya and Yb may be captured by grooves formed along the circumferential directions at an axial end portion of the take up tube 19B.
  • the yarn pressing arm 55 is swung whereas the yarn supporting arm 54 is not swung, with the result that the yarns Ya and Yb are movable in the axial direction of the take up tube 19B (i.e., traversed by the traverse guides 27a and 27b).
  • the yarn supporting arm 54 may be swung in a direction away from the yarn pressing arm 55 without swinging the yarn pressing arm 55.
  • the yarn pressing arm 55 and the yarn supporting arm 54 may be swung in directions away from each other.
  • the yarn Ya (Yb) may be supported by a mechanism different from the two arms 54 and 55.
  • the embodiment above is arranged so that, in order to switch the formation of two packages P by winding yarns Ya and Yb onto two take up tubes 19B and the formation of a single package P by winding a yarn Yg onto a single take up tube 19A, the components of the automatic yarn threading device 24b, such as the suction mouth 51, the yarn moving lever 62, the yarn guide plate 63, the yarn providing arm 53, the yarn supporting arm 54, and the yarn pressing arm 55 are arranged to be removable. This arrangement, however, is not essential.
  • the components above may be arranged to be movable to positions not interfering the yarn Yg at the time of the formation of a single package P.
  • the embodiment above is arranged so that the yarn Ya (Yb) supported by the suction mouth 51 is moved to oppose the take up tube 19B by the yarn providing arm 53 that swings about the shaft 65 which is in parallel to the axial directions of the take up tube 19B, and the yarn is brought into close-contact with the outer circumference of the take up tube 19B by the yarn pressing arm 55 that swings about the shaft 66 which is in parallel to the axial directions of the take up tube 19B.
  • This arrangement is not essential.

  • the automatic yarn threading device may perform the yarn threading into the take up tube 19B by an operation different from the operation of moving the yarn Ya (Yb) to oppose the take up tube 19B and bringing the moved yarn to closely contact the outer circumference of the take up tube 19A.
  • the operator is able to perform yarn threading at a desired timing and hence the yarn threading by the operator is easily synchronized with the yarn threading by the automatic yarn threading device 24a, if, after the winding body 40 having two empty take up tubes 19B is supplied to the cradle 20 and supported by the bobbin holders 22a and 22b, the subsequent operation (swinging of the arms 53-55) is carried out by the automatic yarn threading device 24a when the operator starts the yarn threading by operating a switch or the like.

  • this arrangement is not essential.
  • Two packages P may be formed in such a manner that two yarns Ya and Yb are wound respectively onto two distant parts of a single take up tube 19A that is identical with the tube for winding the yarn Yg. In this case, two packages P are separated from each other by cutting the take up tube 19A after the completion of the winding.
  • the present invention may be utilized for a yarn winder that winds yarns onto three or more take up tubes.
  • yarn threading is carried out at the same timing onto all take up tubes 19B, when automatic yarn threading devices are provided for all take up tubes 19B and yarn threading is carried out onto all take up tubes 19B by the automatic yarn threading devices or when the number of automatic yarn threading devices provided is smaller by one than the number of take up tubes 19B and an operator performs yarn threading onto a single take up tube 19B whereas yarn threading onto the remaining take up tubes 19B is performed by the automatic yarn threading devices.
  • the number of automatic yarn threading devices provided is smaller by two or more than the number of take up tubes 19B, the number of yarns manually threaded by an operator is smaller than the number of yarns in case where yarns are manually threaded onto all take up tubes 19B by an operator. It is therefore possible to reduce the timing differences in the yarn threading onto the take up tubes 19B. Alternatively, the number of operators required for performing the yarn threading onto the take up tubes 19B at the same timing is reduced.
