Title:
FILAMENT YARN BUNDLE FORMING DEVICE AND ITS METHOD
Document Type and Number:
Japanese Patent JP2000001264
Kind Code:
A
Abstract:

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.

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.
