ABSTRACT:
An article or accessory and the method of making the article or accessory from a thermoplastic material is disclosed. Preformed and cut components are formed into an assembly on a female die portion of a fixture having a recess defined therein in the outline configuration of the article. A mating male die has an edge aligning with the recess of the female die. The male die is brought into close proximity to the female die and thermal energy applied. The assembly is sealed along an edge substantially perpendicular to the plane of the assembly leaving only a thin tear edge which can be severed. The resulting edge seal closely approximates turned edge leather construction in appearance.
