Abstract
A cutting mechanism includes a cutter roll and a rotational driving mechanism for rotationally driving the cutter roll. The cutter roll has a roll body and a blade portion protruding from a peripheral surface of the roll body. The blade portion is formed at a same position on a circumference of the roll body and extends in an axial direction of the roll body. The cutter roll is arranged so that the axial direction is at a predetermined angle with respect to a pull-out direction of the reinforcing fiber material. The cutting mechanism further includes a slide mechanism that displaces cutter roll in the axial direction toward a side in the pull-out direction of the reinforcing fiber material at least when the reinforcing fiber material is cut.
