(54) Take-up apparatus


(57) [OBJECT] A take-up apparatus is provided such that an air nozzle is not provided in a yarn path leading from a melt spinning machine to a godet roller, but filaments are not wound around the godet roller.
[MEANS OF REALIZING THE OBJECT] A take-up apparatus (100) includes a melt spinning machine (10) configured to spin filaments (F), a godet roller group (20) configured to feed yarns (Y) made by combining the filaments (F), and a take-up winder (30) configured to wind the yarns (Y) fed from the godet roller group (20) around bobbins (B). While a yarn threading operation is performed on godet rollers (21) and (22), a circumferential speed of the godet rollers (21) and (22) forming the godet roller group (20) is set to a threading speed (Vs) lower than a circumferential speed in a winding period (Pw) and is increased to a winding speed (Vw) after the threading on the godet rollers (21) and (22) is completed and before winding of the yarns (Y) through a threading on the bobbins (B) is started. A circumferential speed of the bobbins (B) is increased to the winding speed (Vw) before the winding of the yarns (Y) through the threading on the bobbins (B) is started.
