Then, roving winding F is reversely rotated by a prescribed amount and a bobbin rail 8 is raised to a position at which the presser paddle 29a corresponds to upper end of the body Fa of the roving winding F or the vicinity of the upper end. Normal rotation of the roving winding F is carried out in the conditions and then, the bobbin rail 8 is lowered to a doffing position.

摘要： PROBLEM TO BE SOLVED: To provide a method for winding a roving yarn in a roving frame by which a wound roving yarn (a roving package) having an expected shoulder shape can be formed stably without causing the collapse of the shoulder.
SOLUTION: The growth ΔΦ of a roving yarn-winding diameter at layer change required when winding the roving yarn so as to form the expected shoulder shape is estimated from the information of a roving tension detector, and the wound roving yarn is formed by determining the inversion position of a bobbin rail by using the estimated growth ΔΦ of the roving yarn-winding diameter. The ΔΦ-estimating model is formed by assuming that the growth ΔΦ of the roving yarn-winding diameter monotonously increases according to the increase of the wound diameter of the roving yarn. The growth ΔΦ of the wound diameter of the roving yarn is calculated from an updated model by updating the ΔΦ-estimating model so that the difference between the growth ΔΦp of the wound diameter of the roving yarn estimated based on the roving tension signal obtained from the roving tension detector, and the growth ΔΦq of the wound diameter of the roving yarn calculated by the model before the update may be reduced.
