Abstract: An optical fiber bundle manufacturing apparatus includes: a winding member; a guide member movable in a direction parallel to a rotary axis, the guide member being configured to guide an optical fiber wire to any one of first winding positions, a converging winding position and second winding positions; and a processor configured to perform processing to move the guide member such that a first branching portion branching into p branches, a converging portion converging the first branching portion branching into p branches into one, a second branching portion branching into q branches, and a connecting portion connecting the first branching portion and the second branching portion are formed in this order by the optical fiber wire.

Abstract: While a winding member is making one rotation, an optical fiber is once skewed relative to the circumferential direction and further shifted by a desired length in the width direction of a circumferential surface. In this state, the winding member winds up the optical fiber. This operation is performed in the same direction every rotation when the winding member rotates (N−1) times. Next, in the N-th rotation of the winding member, a guide member performs the guide to the optical fiber to skew reversely to the direction of shifting in the (N−1) rotations of the winding member.
