CA 2151090

Described is a method of manufacturing a lined moulded part, preferably a moulded part for internal trimming of a vehicle. Such moulded parts comprise a dimensionally stable carrier portion and, connected therewith on the visible side a lining of film, textiles or similar decorative lining material. According to the method, heated blanks of fibrous materials containing binders are shaped to form a carrier portion in a cold tool, and simultaneously connected with the lining. In a first process step, the lining material is inserted with an overhang relative to the contour of the carrier portion into a multi-function tool, and clamped and secured peripherally along the contour of the carrier portion. Thereafter the heated material of the carrier portion is inserted into the multi-function tool and shaped by closing the tool and connected in the region of the surface of the moulded portion with the lining material, an overhang of the carrier portion material being separated by shearing along the edge of the carrier portion. In a third process step, the overhang of the lining is finally trimmed peripherally by a trimming knife. Thereafter the multi-function tool is opened and the lined carrier portion is removed, whereupon the overhang of lining may be bent over about the edge of the moulded part.
