Abstract
A mold apparatus and method for forming a shaped laminate in one step are provided where the laminate includes a cladding layer and a foam backing layer. The apparatus includes a male mold half matable to a female mold half that define a mold cavity. An inlet is mounted on the mold apparatus for introducing foamable materials into the mold cavity. Edge folding members, carried by one of the mold halves, movable from a retracted position to an extended position, fold the cladding layer over at least part of the edge of the foam backing layer. Trim blades are located adjacent to the edge folding members movable from a retracted position adjacent the cavity to an extended position engaging the other mold half to sever the cladding layer to define the finished shape of the laminate.
