ABSTRACT:
An inventive mold is adapted to adhere skin materials having a boundary portion and a resin to each other, and is provided with a resin blocking member which is so embedded as to extend substantially along the boundary portion of the skin materials placed in the mold, and a movable member for projecting the resin blocking member from a molding surface. If such a mold is used, a flow of the resin supplied into the mold can be controlled by projecting the resin blocking member to thereby control an arrival timing of the resin at the boundary portion. Thus, displacement of the boundary portion and wrinkling can be securely prevented from occurring.
