Abstract
Abstract A process for forming composite plastic and fabric articles to a desired shape wherein a sheet of thermoplastic material and a stretchable fabric are separately supported in spaced generally parallel planes over a forming surface with the fabric closer than the sheet to the forming surface. The sheet is heated to a pliable state and forced toward the molding surface to carry the fabric as well as the sheet into conforming relation with the mold surface. The resulting shaped object is chilled in the mold into a rigid condition under which it may be removed and trimmed or vice versa.
