Latest Patents

Vean Elfes holds a patent for a heat bonded composite plastic article and the method and apparatus for its production. This invention involves a sheet of solid thermoplastic material, such as polypropylene, combined with an envelope or jacket of urethane foam. The jacket of foam is heat staked directly to the thermoplastic material in multiple adjacent but discontinuous locations. This process results in permanent compression of the foam and welding of the solid thermoplastic material into the foam. The areas on the opposite faces of the article are in substantially exact registration with one another. The apparatus for producing this article features a press-like combination of heated platens mounted on pivot arms, operated by air cylinders. Each platen is equipped with stakes that perform the compression and welding functions. Additionally, one of the platens carries a knife edge to trim the urethane foam around the periphery of the solid plastic body. An assembly method using a semi-automated apparatus is also disclosed in her patent.
