PURPOSE: To prevent a package from profile deformation or the like in a method of winding yarn with a constant wind ratio by increasing traverse speed at least once during yarn winding and thereafter again winding the yarn with a constant wind ratio.

CONSTITUTION: The rotational frequency of a touch roller TR contacting with a costant pressure a package P on a spindle S rotated by a motor M1 is detected by a first pulse oscillator 3. The rotational frequency per a predetermined time and a set value from a setter 2 are compared with each other by a first judging means 5. And according to the comparison result is feedback controlled the motor M1. Also, the rotational frequency of the motor M1 is detected by a second pulse oscillator 8, and in a second judging means 10, a calculating means 14 calculates the traverse speed of a traverse guide TG from the outputs directed according to respective set values about the rotational frequency of the motor, wind ratio from a setter 11, rotational speed of a spindle and traverse speed increasing period to control a motor M2 for traverse.
