Abstract: PROBLEM TO BE SOLVED: To prevent meandering of filament yarn and deterioration of quality due to losing its shape of a clustered filament yarn bundle by arranging a pair of filament yarn holding bars at a space, continuously winding a filament yarn round the paired filament yarn holding bars in the outer peripheral direction, and moving the filament yarn in the axial direction of the filament yarn holding bar. SOLUTION: Plural filament yarn 1a, 1b, 1c are guided to a tension applying plate by each filament yarn by a partition guide 9 and a filament yarn path guide 10. A direct acting machine 19 is moved forward and backward, whereby arbitrary compression force is transmitted to a filament yarn clamped between two tension applying plates through an elastic body and a film to apply suitable tension thereto. The filament yarn 1 which has passed through the tension applying plates is guided to the peripheral part of a filament yarn holding bar 2 by a take-up guide 7. The take-up guide 7 is rotated about the outer peripheral part of the paired filament yarn holding bars by a direct-acting actuator 6 to wind the filament yarn 1 round the filament yarn holding bars 2a, 2b. Further, the take-up guide 7 is moved pitch by pitch in the longitudinal direction of the filament yarn holding bar 2 with every turn.
