PCT No. PCT/JP94/00733 Sec. 371 Date Oct. 30, 1995 Sec. 102(e) Date Oct. 30, 1995 PCT Filed Apr. 28, 1994 PCT Pub. No. WO94/25244 PCT Pub. Date Nov. 10, 1994The present invention is to improve a laminate molding method and a laminate-molding apparatus for manufacturing molded products that have an external appearance of excellent quality. For this purpose, according to a molding method, by which a mold clamping device (3) laminates sheet of skin material (Mm) and a core resin (200), the tension of the sheet of skin material Mm, which is inserted into a cavity (9) between a clamped fixed metal mold (11) and a clamped movable metal mold (12) and is laminated by the movable metal mold (12), is varied, continuously or in a stepped manner, in consonance with the insertion amount of the sheet of skin material (Mm). The laminate-molding apparatus comprises a skin material holding device (40) that is attached to the mold clamping device (3), a detector (31) that detects a stroke or a time at the time of clamping the movable metal mold (21), and a skin material holding controller (50) that, upon the receipt of a detection signal, outputs to the skin material holding device (40) a command for altering the tension of the sheet of skin material.
