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.

Claims

1. A bonding device for fabricating a vehicle interior component comprising a core member and a surface skin member covering a front surface of said core member and folded back over an edge and a concave reverse surface of said core member at a peripheral part of said surface skin member, said device comprising:

a bonding station for bonding said surface skin member onto said front surface of said core member;

a peripheral part folding back station for folding said peripheral part of said surface skin member over said edge of said core member and securing said peripheral part of said surface skin member onto said concave reverse surface of said core member; and

conveying means for carrying an assembly of said core member and said surface skin member from said bonding station to said peripheral part folding back station;

wherein said bonding station includes a first die made of a block of resilient material for mounting said surface skin member thereon and said conveying means includes means for retaining said core member and means for pushing said core member against said surface skin member mounted on said first die made of a block of resilient material; and

wherein said peripheral part folding back station includes a second die for retaining said assembly of said core member and said surface skin member, a plurality of first slide bars for folding said peripheral part of said surface skin member over said edge of said core member which are slidable across an edge of said core member, and a plurality of second slide bars for pressing said peripheral part of said surface skin member against said concave reverse surface of said core member which are slidable along and substantially in parallel with said concave reverse surface of said core member adjacent said edge of said core member.

2. A bonding device according to claim 1, wherein said first and second dies each comprise lower dies, and said conveying means comprises an upper die for retaining said core member.

3. A bonding device according to claim 1, wherein said upper die includes vacuum suction holes for retaining said core member thereon.
