LAMINATION METHOD AND LAMINATION DEVICE

To provide a technique for automatizing a lamination work of a woven prepreg material. A lamination order is decided. A plurality of piece parts 10 is cut out from a prepreg base material. In accordance with the order, the cut-out piece parts 10 are placed on a base sheet 20. The base sheet 20 having the piece parts 10 placed thereon is wound into a roll shape. The base sheet 20 is fed from the feeding reel 31 to be wound by the winding reel 32. A compaction roller 33, in accordance with the order, causes the piece parts 10 to be pressure-bonded against a jig 40 or a laminated body (in the middle of formation) to transfer the piece pats 10 from the base sheet 20. Repetition of the above operations enables lamination of the prepreg materials and achieves formation of a targeted laminated body 50 (final product).
