Abstract

PROBLEM TO BE SOLVED: To make it possible to execute a winding on a continuous filament body while a stable tension is applied even to a thin wire by a method wherein the position in the rotating shaft direction of the dancer of the tension part of a feed wire is detected and the speed of rotation of a motor for filter rotational drive use and the speed of rotation of a motor for spool axis rotational drive use are calculated and controlled on the basis of information on the detected position of the dancer. SOLUTION: A wire 31b is fed through a spool 11 and is wound on a continuous filament body 31, which is used as a wound core, from the point of a wire material nozzle 14. At the same time, the speed of rotation, which feeds the length component of the wire 31b wound on the body 31 which is transferred from the left to the right at a specified pitch, of the body 31 is added to the speed of rotation of a cylinder 10 to rotate the spool 11 in the same direction as that of the body 31, whereby a winding part 31a is continuously formed. The speed error of change of the body 31 due to a change in the tension of the wire 31b is detected by a length measuring sensor 22 as the positional change of a detecting plate 24, the error is calculated to make a control correction and the speed of rotation of a motor 19 for drive use is modified to the optimum value of a winding of the wire 31b. Thereby, even a thin wire material is never disconnected and it becomes possible to execute stably a continuous winding on the body 31.
