  • Patent number: 5609709
    Abstract: A bonding device and bonding process for a surface skin member of a vehicle interior component which can reliably fold back and secure a peripheral part of a surface skin member onto the reverse surface of a core member without involving any positional deviation between the core member and the surface skin member even when the width of the peripheral part is small. A block of elastic material is used for a lower die for mounting a surface skin member in a bonding station, and slide bars are arranged around the lower die in a peripheral part folding back station disposed adjacent to the bonding station for provisionally shaping the peripheral part of the surface skin member. Further, vertically moveable bars are arranged around an upper die for mounting the core member thereon for pressing the peripheral part of the surface skin member which has been provisionally shaped against the reverse surface of the core member.
