A molding machine places strips of a tape material side by side and molds the tape material into a molded shape having a web portion and a flange portion, the tape material including a continuous fiber bundle extending in a longitudinal direction. The molding machine includes spreading unit able to increase a width of the tape material by spreading the tape material, and a laying roller that places the tape material which has passed through the spreading unit onto a surface of a molding tool. The spreading unit continuously changes the width of the tape material to avoid generation of a gap between adjacent strips of the tape material, the adjacent strips being adjacent to each other when the tape material is placed on the surface of the molding tool, and the laying roller places the strips of the tape material side by side in a plurality of rows.

Fiber-material molding machine and fiber-material molding method

A preform figuring method includes mounting and stacking sheet-shape fibrous preparations that have been or are yet to be impregnated with a thermosetting resin on a figuring die that has first and second figuring surfaces at least either one of which is a curved surface and making a preform for a composite material which has a curved surface that corresponds to the curved surface of the figuring die as a stack of the fibrous preparations which has layers by bending the fibrous preparations mounted on the first figuring surface onto the second figuring surface. At least a fraction of the layers that constitute the stack are formed by mounting sheet-shape fibrous preparations on the first figuring surface or the fibrous preparation adjacent in a stacking direction so that the fibrous preparations partly overlap and bending portions of the fibrous preparations mounted so as to overlap onto the second figuring surface.
