PARTIALLY SEPARATED FIBER BUNDLE, INTERMEDIATE BASE MATERIAL, MOLDING, AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2019/151076

A1

Provided are: a method for producing partially separated fiber bundles that is capable of stably separating fiber bundles continuously over long periods even when there are spliced parts in the partially separated fiber bundle; and a method for producing an intermediate base material or molding using the same. For said purpose, when conveying fiber bundles, which have spliced parts resulting from joining fiber bundles to each other, along the longitudinal direction, the present invention provides a method for producing partially separated fiber bundles that separates portions of the fiber bundles by thrusting a protruding part of a separating means into the fiber bundles, wherein the timing for the thrusting by the separating means into the fiber bundle is varied on the basis of spliced part position information obtained by detecting the spliced parts.
