Earlby Wakefield has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7275781
    Abstract: The invention provides a method of forming structural components for automotive vehicles from elongated tubular blanks. A longitudinally oriented tubular blank comprised of a thermoplastic material is provided. The tubular blank is fluidformed in a fluid forming cavity by orienting in a hoop direction of the tubular blank to conform the tubular blank to a predetermined shape of the fluid forming cavity to provide structural components having increased strength over the tubular blank. The structural components have biaxial and/or triaxial orientation. Fluid forming is performed within an orientation temperature range above the glass transition temperature and below the softening point of the thermoplastic material. Structural components include bumper beams, intrusion beams in vehicle doors, crush cans, and frame members. The produced structural components are strong and light weight.

  • Publication number: 20040031559
    Abstract: Automotive trim strips (32) are made by extruding a thermoplastic material onto a foil carrier (24). The foil carrier (24) has a receiving surface having a low strength adhesive for releasably receiving the thermoplastic material (22). The thermoplastic material is end formed to contour ends of the thermoplastic material such that an automotive trim strip (32) is formed having a predetermined final length. The automotive trim strips (32) are then cooled. The foil carrier (24) is removed presenting a substantially flat surface for receiving adhesives for permanently attaching the automotive trim strip (32) to the vehicle.

  • Patent number: 5904884
    Abstract: A process for forming a specific length of extruded thermoplastics material trim strip for automobiles includes the step of extruding the strip directly onto an endless carrier belt moving at a speed matching the emergence speed of the extrudate. The extrudate, therefore, is less subject to stresses causing unpredictable length changes on cooling. It is therefore possible to predetermine the cooled, matured, final lengths of strip and to provide moulded end portions on-line.
