A process for applying a PVC heel pad to automotive carpeting to eliminate the necessity of pre-forming the heel pads before they are applied to the carpet and the products formed thereby, including the steps of applying a hot melt adhesive composition between the carpet and the back side of an unpatterned PVC sheet; positioning the composite which includes the carpet, adhesive and unpatterned PVC sheet in a metallic heel pad patterned mold; and forming in situ a pattern molding on the PVC pad simultaneously with the adhesion of the PVC pad to the carpet.
