Abstract (en)

[Problem to be solved] To ensure stable and smooth unwinding of yarn from the yarn supply package.[Solution] A drawing and false twisting machine 1 includes a peg 12 on which a yarn supply package 5 wound with yarn 3, which is POY, can be set; a processing position 35 where the yarn 3 from the yarn supply package 5 set on the peg 12 is processed to form a wind package; and a yarn guide that guides the yarn 3 toward the processing position 35 at a downstream end of a balloon formed by the yarn 3 unwound from the yarn supply package 5 set on the peg 12. The yarn supply cart 50 is a work robot that performs work for the drawing and false twisting machine 1. The yarn supply cart 50 includes a yarn supply package position adjustment device 57 that moves at least one of the yarn supply package 5 from which the yarn 3 is being unwound and the yarn guide 13 to decrease the distance between the yarn supply package 5 and the yarn guide 13 as the unwinding of the yarn 3 from the yarn supply package 5 progresses.
