Abstract (en)
[origin: EP0965553A2] The invention provides a traverse apparatus having rotating wings which is capable of providing a well-formed cone-shaped package and therefor comprises two yarn guide rotating wings 10a and 10b that rotate in opposite directions, and elliptical driven gear 14 provided at the input section of the yarn guide rotating wings 10a and 10b, and an elliptical drive gear 16 engaged with the driven gear 14 and provided at the output section of a drive motor 21, wherein the yam guide rotating wings 10a and 10b are pulsated and rotated by means of the gears 14 and 16 to change the traverse speed in the axial direction of a cone-shaped package 2, and the engagement of the gears 14 and 16 is set so that the traverse speed is fast on the shorter diameter side 2a of the package 2 and slow at the longer diameter side 2b of the package 2. The amount of yarn 1 wound is small on the shorter diameter side 2a and large on the longer diameter side 2b, thereby making it possible to provide a well-formed cone-shaped package 2. <IMAGE>
