Abstract (en)

A fiber bundle condensing device (100) includes a condensing device (110) configured to condense a fiber bundle (F) and including a delivery bottom roller (112) that is mounted on a rotary shaft (111) and transports the fiber bundle (F), a countershafts (130) configured to drive the rotary shaft (111), a driven gear (113) mounted on the rotary shaft (111), a drive gear (132) mounted on the countershaft (130). A plurality of the countershafts (130) corresponding to a plurality of the condensing devices (110) are connected by a coupling (150). A conditional expression W > d ≥ (1/4) x W is satisfied, where W represents a width of the drive gear (132) and d represents a distance between ends of the plurality of countershafts (130) connected by the coupling (150).
