Abstract (en)
[origin: EP0394986A2] A yarn traversing apparatus comprises: a first traverse member, which is disposed downstream by a predetermined distance from a fulcrum for traverse motion, for traversing the yarn from a center toward ends of traverse stroke; and a second traverse member, which is disposed downstream by a predetermined distance from the first traverse member, for traversing the yarn from the ends of traverse stroke toward the center of traverse stroke; the first traverse member comprising a rotary blade moving from the center of traverse motion toward the ends of traverse stroke and a guide rail restricting a speed of the yarn conveyed by the rotary blade, so that speed of the yarn conveyed by the first traverse member is made substantially constant; the second traverse member comprising a rotary blade moving from the ends of traverse stroke toward the center of traverse motion and a guide rail restricting a speed of the yarn conveyed by the rotary blade of the second traverse member, so that a speed of the yarn conveyed by the second traverse member is made almost same as that of the first traverse member at the center of traverse motion and is gradually decreased from a speed between 1.5 and 7 times of that of the first traverse member to that of the first traverse member at the ends of traverse motion.
