Document Type and Number:
Japanese Patent JP3346872
Kind Code:
B2
Abstract:
A method of continuously taking out a twist-free fiber bundle from the inner side of a plurality of fiber bundle packages each having a hollow cylindrical shape is disclosed. The trailing end of a fiber bundle package and the leading end of another fiber bundle package are spliced to each other in advance. The plurality of fiber bundle packages thus spliced are attached to a body of revolution, and a fiber bundle is then taken out at a speed which is determined based on the taking-out speed of the fiber bundle in a direction so as to eliminate twist of the fiber bundle thus taken out while the rotary member is rotated. Also disclosed is a method of manufacturing a resin structure reinforced with long fibers using the thus prepared twist-free fiber bundle by impregnating it with a resin while drawing.
