(54) Method of forming cop for spinning machine


(57) A cop forming method for a spinning machine wherein the method can protect the wind shape of a cop against deformation even when the spinning speed changes during the cop forming. The method of forming a cop in a spinning machine through up/down reciprocative motion of a ring rail for which a chase stroke, a chase speed, a step length and so forth have been set previously includes a step of correspondingly modifying the up/down reciprocative motion of the ring rail so that when the spinning speed becomes lower, the step length is increased correspondingly or the chase speed is increased correspondingly, while when the spinning speed becomes higher, the step length is decreased correspondingly or the chase speed is decreased correspondingly.
