YARN-FEEDING UNIT FOR FILAMENT WINDING APPARATUS, FILAMENT WINDING APPARATUS AND METHOD FOR PRODUCING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a yarn-feeding unit for a filament-winding apparatus in which a spread filament bundle can stably be wound around a filament bundle-wound member without any driving force.

SOLUTION: The yarn-feeding unit 15 is attached to an attaching portion 22 of the filament winding apparatus so that a supporting part 23 may be rotatable against the attaching portion 22. The supporting part 23 has a pair of supporting walls 23a and an exit guide 25 is attached via an attachment piece 26 to the supporting wall 23a for guiding the filament bundle F that is drawn out by being accompanied with the rotation of the filament bundle-wound member. The exit guide 25 has a guide face 25a having a concave curved shape toward the rotary axis side 01 of the supporting part 23 and the apogee point from the rotary axis shaft 01 is in the range of the guide face through which the filament bundle F can pass. Filament bundle-expanding guides 28a, 28b are set to the support part 23 in order to expand the filament bundles, which are arranged on the upstream side of the filament bundle F in the direction that the filament bundle on the outlet guide 25 is drawn out.
