This invention produces three-dimensional shapes such as window lineals by first lining a foam die with a continuously moving reinforcing veil. Once the veil is in the foam die, a foam is blown into the die. The foam expands in the die forcing the veil against the die wall. The veil is selected so that the foam never fully penetrates the veil, but adheres to it. The material exiting the foam die is now properly shaped to enter the curing die. Resin is then injected onto the foam core where it penetrates the veil, is cured in the heated curing die and exits as a finished product of a plastic skin adhered to a foam core with a veil sandwiched therebetween.
