(54)	Yarn winding machine and yarn winding method

(57) An automatic winder (10) includes a traverse device (27), a correction width setting section, and a traverse control section (46). The traverse device (27) traverses a yarn to be wound into a package (30). The correction width setting section sets an end correction width for correcting a predetermined target traverse stroke dependent on a predicted package winding diameter. The traverse control section (46) controls the traverse device (27) so as to traverse the yarn under a traverse width determined in accordance with the end correction width that has been set by the correction width setting section.
