Document Type and Number:
Japanese Patent JP4774930
Kind Code:
B2
Abstract:
A fiber bundle concentrating device includes a fiber bundle delivery portion including a nip roller (19a,20), a suction portion (17) having a guide surface (29b), and a perforated belt (18). The fiber bundle delivery portion is located downstream of a final delivery roller pair (14,15). The guide surface (29b) has a suction hole (29a) at least in a section upstream of a nip point of the delivery portion in a moving direction of the fiber bundles (F). The perforated belt (18) rotates while sliding on the guide surface (29b). The perforated belt (18) is formed as a sheet body that contains intersecting sets of yarns (34). Part of intersecting portions (35) of the yarns (34) are fused such that fused regions (37), where the fused intersecting portions (35) are adjacent to each other, and non-fused regions (38), where the non-fused intersecting portions are adjacent to each other, are alternately arranged at least in a circumferential direction of the perforated belt.
