A covered article such as an automotive trim panel comprises a substrate having a front surface to be covered, a back surface and a plurality of holes extending through it for vacuum drawing a trim cover stock against the front surface. The substrate has sets of parallel saw-tooth holder grooves in a peripheral margin of the back surface adjacent to an edge of the substrate that is to be wrapped by the trim cover stock and transverse manifold grooves that communicate with the holder grooves. An adhesive is applied to the front surface and the peripheral margin and the substrate is supported on a vacuum buck so that the peripheral margin overhangs the buck and the manifold grooves communicate with a vacuum source of the buck. The trim cover stock is drawn against the front surface of the substrate and a marginal portion of the trim cover stock is simultaneously drawn against the peripheral margin of the back surface by vacuum to wrap the trim cover stock around the edge of the substrate. The marginal portion of the trim cover stock is drawn into the bottom of the holder grooves to provide a mechanical interlock between the marginal portion of the trim cover stock and sharp edges of the saw-tooth holder grooves. Alternate substrates have a porous strip of various cross sections.

A method of making a covered article having a substrate and a cover comprising: providing a substrate having a front surface to be covered, a back surface and a plurality of holes extending through it from the front surface to the back surface for vacuum drawing a cover against the front surface of the substrate, providing fluid passages at the back surface in a peripheral margin adjacent an edge of the substrate to be wrapped by the cover, supporting the substrate on a vacuum buck so that the peripheral margin of the back surface overhangs the vacuum buck and the fluid passages communicate with a vacuum source of the buck, and forming a cover stock against the front surface of the substrate and a marginal portion of the cover stock against the peripheral margin of the back surface by pressure differential and with an adhesive disposed therebetween to provide a cover stock that is wrapped around the edge of the substrate and adhered to the substrate.
