Abstract
A fiber width adjusting apparatus includes a rotary body. The rotary body is configured to rotate around a rotation axis while interposing a sheet-shaped fiber, and cause, by frictional force generated between the rotary body and the sheet-shaped fiber, force to act on the sheet-shaped fiber while feeding the sheet-shaped fiber in a feed direction to vary a width and an orientation angle of the sheet-shaped fiber. The sheet-shaped fiber is impregnated with a resin or is before the impregnation with the resin. The rotation axis is parallel to a thickness direction of the sheet-shaped fiber. The force contains a component that is in a direction perpendicular to the thickness direction and to the feed direction.
