    (54) A yarn traversing apparatus


    (57) The comprises:
       a first traverse member (23,24), which is disposed downstream by a predetermined distance from a fulcrum (8) for traverse motion, for traversing a yarn (y) from the center toward the ends of a traverse stroke; and
       a second traverse member (25,26), which is disposed downstream by a predetermined distance from the first traverse member (23,24), for traversing the yarn (y) from the ends of the traverse stroke toward the center of the traverse stroke;
       the first traverse member (23,24) comprising a rotary blade moving from the center of the traverse stroke toward the ends of the traverse stroke and a guide rail (37a) restricting the speed of the yarn (y) conveyed by the rotary blade, so that the speed of the yarn (y) conveyed by the first traverse member (23,24) is made substantially constant;
       the second traverse member (25,26) comprising a rotary blade moving from the ends of the traverse stroke toward the center of the traverse stroke and a guide rail (38a) restricting the speed of the yarn (y) conveyed by the rotary blade of the second traverse member (25,26), so that the speed of the yarn (y) conveyed by the second traverse member (25,26) is made almost same as that of the first traverse member (23,24) at the center of the traverse stroke and is gradually decreased from a speed between 1.5 and 7 times of that of the first traverse member (23,24) to that of the first traverse member (23,24) at the ends of the traverse stroke.
