MANUFACTURING APPARATUS AND METHOD OF MANUFACTURING A TOW PREPREG

The invention provides a manufacturing apparatus and a method of manufacturing a tow prepreg. A resin supply unit (30) of a manufacturing apparatus (10) supplies a resin (14) to a roller surface (28a) of an impregnated roller (28) which is capable of rotating at a constant speed. A transport mechanism (20) brings the fiber bundle (12) into contact with the resin (14) on the roller surface (28a) and thereby forms a tow prepreg (16) while the fiber bundle (12) is being transported. A fineness acquisition unit (26) acquires as a fineness acquisition value a fineness, which is defined by a mass per unit length of the fiber bundle during conveyance thereof before being brought into contact with the resin. A resin supply amount control unit (32) controls the resin supply amount based on the fineness acquisition value, in a manner so that a resin content of the tow prepreg (16) becomes a target resin content. As a result, the resin content of the tow prepreg can be controlled with high precision regardless of variat
