Abstract: A continuous forming apparatus of a fiber reinforced composite includes a tension detection mechanism, a drive motor, and a drive control device. The drive control device is configured so that a material roll is rotationally driven in a delivery direction of a reinforced fiber base material during a time period from a time point of end of pressurization in a forming process to a time point of end of a pulling-out process, and is also configured to perform tension control on the reinforced fiber base material based on a detected tension value from the tension detection mechanism and a target tension value, during a time period from a time point of start of the pulling-out process to a time point of end of the pressurization in the forming process in a next forming operation.

Abstract: A slitter device includes a first tension detecting unit for obtaining a raw-cloth tension value which is a tension value of a sheet material fed out from a let-off mechanism, a second tension detecting unit for obtaining a divided material tension value which is the sum of the tension values of each of divided sheet materials, and a drive control device which includes a comparator to which the first tension detecting unit and the second tension detecting unit are connected, and which compares the raw-cloth tension value and the divided material tension value with each other; and a drive controller which controls an operating state of a roll driving motor such that the raw-cloth tension value and the divided material tension value coincide or substantially coincide with each other based on the comparison result of the comparator.

Abstract: A method for manufacturing a reinforcing fiber base material includes a placement step of placing a sheet-shaped reinforcing fiber material piece, in which reinforcing fibers are arranged so as to extend in one direction and bound together with a thermoplastic resin, on a table so that the orientation direction of the reinforcing fibers is at an angle with respect to a longitudinal direction of the reinforcing fiber base material, and a welding step in which, in a state in which a previously placed reinforcing fiber material piece and the reinforcing fiber material piece placed subsequent thereto are abutted against each other in the longitudinal direction, adjoining edges of the two reinforcing fiber material pieces are welded together to form a continuous sheet shape.

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.
