METHOD AND APPARATUS FOR PRODUCING TWISTED FANCY YARN AND TWISTED FANCY YARN

摘要

PROBLEM TO BE SOLVED: To provide both a method and an apparatus for producing a twisted fancy yarn freely changing the number of twists of a winding yarn per unit length of a core yarn in the twisted fancy yarn in the longitudinal direction, and to provide the twisted fancy yarn for knitted and woven texture capable of giving a specific design in weaving. ;SOLUTION: In this apparatus for producing the twisted fancy yarn 10, comprising a hollow spindle 2 which is rotatably supported and has an inner hole through which the core yarn 3 is passed, a bobbin 5 which is attached to the spindle 2 and wound with the winding yarn 4, a spindle rotation apparatus 7 for rotating the spindle 2, a winding yarn guide auxiliary tool 6 for guiding the winding yarn 4 on the bobbing 5 in the direction of the tip of the spindle 2 and a twisted yarn sending apparatus 9 for twisting the winding yarn 4 on the core yarn 3 in the vicinity of the tip of the spindle 2 to form a twisted yarn 8 and sending out the twisted yarn at a fixed speed, a change gear 12 for changing the sending out velocity of the twisted yarn 8 from a low-speed side to a high-speed side is attached to the twisted yarn sending out apparatus 9 and a program setting apparatus 13 for outputting a speed change signal of the sending out speed of the twisted yarn 8 based on a fixed program is connected to the change gear 12.;COPYRIGHT: (C)2001,JPO
