Abstract
A yarn traversing apparatus includes a first traverse member having rotary blades for traversing a yarn from a center toward ends of a traverse stroke, and a second traverse member having rotary blades for traversing the yarn from the ends toward the center of the traverse stroke in order to wind the yarn onto a bobbin to form a yarn package. Guide rails are provided so as to maintain the speed of the yarn constant as it is conveyed by the first traverse member, and to gradually decrease the speed of the yarn from the ends of the traverse stroke to the center of the traverse stroke as it is conveyed by the second traverse member, from a speed that is 1.5 to 7 times that of the first traverse member, to a speed substantially the same as that of the first traverse member.
