  • Patent number: 8758544
    Abstract: A method and apparatus for forming a vehicle window assembly utilizes one or more induction heating devices to adhesively bond an item of hardware to a glass substrate, which substrate is then adapted to fill an opening in a vehicle body. Preferably, the induction heating device(s) and one or more assembly aids are components of an assembly fixture which allows for automated or semi-automated production of such vehicle window assemblies.
    Type: Grant

  • Publication number: 20070196572
    Abstract: A process for preparing a pressure sensitive adhesive using a modified planetary roller extruder is described. The process in accordance with one aspect of the invention includes introducing primary raw materials including a non-thermoplastic elastomer into a feeding section of the modified planetary roller extruder, conveying the raw materials from the feeding section to a compounding section of the modified planetary roller extruder, continuously mixing the primary raw materials in the compounding section to produce a homogeneous adhesive composition. The adhesive composition may be applied to a web-form material. The compounding section of the modified planetary roller extruder includes a main spindle surrounded by and intermeshed with a plurality of planetary spindles at least one of which is a double transversal mixing spindle having a plurality of back-cut helical flights.
