ABSTRACT:
Disclosed herein is a method of producing a trim board, which comprises by steps: (a) hot-pressing trimming and piercing a resin-impregnated substrate at the same time to produce a shaped substrate; (b) laying an outer skin member onto one surface of the shaped substrate with an interposal of a hot-melt sheet therebetween; (c) pressing the outer skin member against the shaped substrate while the shaped substrate is still hot, thereby to produce a skin covered unfinished trim board; (d) trimming and piercing the outer skin member at portions which correspond to the portions of the shaped substrate at which the trimming and piercing have been carried out at the step (a), the step (d) being so made that a peripheral portion of the outer skin member at which the trimming and piercing have been effected protrudes by a certain degree beyond a peripheral edge of the shaped substrate at which the trimming and piercing have been effected; and (e) turning back the protruding peripheral portion of the outer skin member and fixing the same to a peripheral back portion of the shaped substrate.
