Thermoplastic film articles

Abstract

Abstract A process is disclosed for making articles of ornamental or unusual appearances by cutting and heating operations performed on a plurality of layers of thermoplastic film material which has been stretched, preferably in two directions at right angles to each other, during manufacture, so as to fuse the layers of material together at least at their edges and in most cases cause contraction of the film in directions parallel to their faces and expansion in a direction perpendicular thereto. A particularly effective procedure is to form an elongated composite roll or bundle of the film material or rods of thermoplastic material or both and to then slice the resulting structure transversely into wafers. These wafers may be heated differentially to cause them to deform into unusual shapes. A number of different types of articles thus made are also shown.
