Abstract (en)
[origin: EP1734161A2] A fiber bundle guiding device (30) is located between a middle bottom roller (13) and a back bottom roller (14). The guiding device (30) guides a fiber bundle (F) moving from an upstream side to a downstream side such that the width of the fiber bundle (F) is reduced. The guiding device (30) includes guiding members (31) and an oscillation portion (32). Each guiding member (31) has a guiding surface (31a) that extends along the moving direction of the fiber bundle (F) to be guided. The oscillation portion (32) vibrates the guiding members (31) to generate a sound pressure for preventing the fiber bundle (F) from contacting the guiding surfaces. Therefore, it is possible to guide a fiber bundle without contacting the fiber bundle, and to prevent deterioration over time of frictional state of the guiding surfaces due to abrasion and collection of foreign matter (Fig. 1B).
