Abstract: A prepreg automatic layering device includes a rotary die-cutter, a cutting mechanism and a control device. The rotary die-cutter, by cutting a prepreg sheet only in the width direction, cuts out a prepreg cut-out section in which a prepreg cut section and an unnecessary portion are integrated. The cutting mechanism is disposed before a layering stage, and separates a portion corresponding to the prepreg cut section and a portion corresponding to the unnecessary portion by cutting the prepreg sheet in the direction in which the prepreg sheet is conveyed. The control device controls the cutting mechanism.

Abstract: The method for producing an assembly is a method for producing an assembly equipped with a member to be reinforced (20), a reinforcing member body (41), and a filler (42), wherein the reinforcing member body (41) has a pair of flanges (44) arranged spaced on the surface (20B) of the member to be reinforced (20), a web (45), and a connection portion (46) which connects the flanges (44) and the web (45) and forms a filler space (V) with the surface (20B). The method for producing an assembly includes a step for inserting a filler (42) into the filler space (V), a step for attaching a crack control member (43) to cover the end of the filler (42), a step for joining the flanges (44) and the member to be reinforced (20), and a step for curing at least the member to be reinforced (20).

Abstract: Compactors arranged adjacent to each other in one direction are independent of one another. A raising and lowering mechanism raises and lowers the compactors independently of one another. A control device controls the raising and lowering mechanism.
