摘要

Press molding method comprises feeding sections of fiber mat into molding press, spraying on resin, closing mold, allowing resin to cure and trimming flash from molding. Press molding method comprises: (a) feeding sections (7) cut from a continuous belt of fiber mat (2) into the female section (22) of a molding press (20) using robot arms (58, 58') and fastening it in place with a frame (24); (b) spraying resin on to the section in the mold; (c) closing the mold on the frame/mat combination (26); (d) keeping it closed while the resin cures; an (e) removing the molded component and trimming off the flash. An Independent claim is included for a plant for carrying out the method comprising: (a) a molding press (20); (b) a frame (24) for clamping a fiber mat section in the female section of the press; (c) robot arms for moving mat sections fitted with grippers (59') and/or spray heads for resin; (d) containers (66) for fittings (9) and premoldings (10); and (e) a reel (50) of fiber mat with retaining strip (51) for the free end of the mat and cutter (52).
