Abstract (en)
A method of forming a cop (40) by upward winding yarn (Y) around a bobbin (B) in a spinning machine by means of filling building is characterized by the step of winding the yarn (Y) to an upper limit position (UL) of a ring rail (18) by normal winding operation where upward displacement (Du) of a lower reversal position (PL) of the ring rail (18) is constantly the same while a chase length (Lc) is kept constant, and the step of increasing winding quantity of the yarn (Y) by lifting/lowering the ring rail (18) so that the chase length (Lc) gradually decreases while an upper reversal position of the ring rail is lowered from the upper limit position of the ring rail.
