Provided is a device for manufacturing a chopped fiber bundle that is provided with a cutter roll obtained by attaching one or a plurality of disc blades on the outer circumferential surface of a roll main body such that the axis of rotation of the roll main body matches the center axis, and a nip roll disposed parallel to the direction of the axis of rotation of the roll main body, and that feeds reinforcing fiber yarn between the nip roll and cutter roll and continuously cuts the same, wherein the device is characterized by being provided with at least a rotary drive mechanism for rotating the cutter roll, and also being provided with a back and forth drive mechanism for back and forth drive of the cutter roll in the direction of the axis of rotation of the cutter roll, and/or a traverse guide for traversing the reinforcing fiber yarn in the direction of the axis of rotation of the roll main body. The present invention provides a device for manufacturing a chopped fiber bundle that can, by means of a simple device, continuously cut the reinforcing fiber yarn obliquely, and further, that is provided with a traverse guide that makes oblique cutting at a small angle possible, and provides a method for manufacturing a chopped fiber bundle. |
