发明名称 Method of laminating a trim panel and folding a cover sheet edge around the panel rim
摘要 An improved method and apparatus for laminating a cover sheet onto a substrate, and folding and laminating the cover sheet edges around the back side of the substrate rim are especially suited to making finished trim panels having a strongly contoured three-dimensional configuration. A carrier frame holds the cover sheet material with a desired tension until the lamination has begun, to avoid wrinkling and sagging of the cover sheet material on a strongly contoured three-dimensional substrate. A lower mold receives the substrate, while an upper mold laminates the cover sheet onto the substrate. The upper mold can be retracted into or extended from a frame that forms a nest, while edge-folding tools are laterally movably arranged around the perimeter of the upper mold nest. The lamination and molding is initiated with the upper mold extended beyond or below the plane of the edge-folding tools and the cover sheet still held by the carrier frame, and then the two molds together are retracted above the plane of the edge-folding tools to begin the edge-folding step.
