Patents by Inventor Frank Springmeier

Frank Springmeier 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: 6990795
    Abstract: A texturing machine for draw texturing a plurality of synthetic multi-filament yarns and which includes a plurality of side by side processing stations. Each of the processing stations comprises a plurality of processing units for advancing, texturing, drawing, and winding the yarn. At least one of the processing units is driven by an electrical individual drive, with the individual drives of the processing units of adjacent processing stations being controlled by a common group frequency changer. To enable a separate connection and disconnection of the individual drives with a simultaneous group control, the electrical individual drive of each processing unit includes an asynchronous unit and a synchronous unit. In the case of a predetermined desired frequency, this permits an automatic startup and maintenance of the desired frequency, which leads to a high degree of uniformity of the yarn treatment in each processing station.

  • Patent number: 6069426
    Abstract: A godet for guiding and advancing a yarn with a rotating godet jacket. The godet jacket is mounted to a rotor shaft, which is driven by means of a three-phase motor. The three-phase motor is controlled via a frequency inverter, which is mounted in a housing, whose interior accommodates the electronic subassemblies of the frequency inverter in a stationary and heat transferring manner. The housing of the frequency inverter is firmly connected to the housing of the three-phase motor.
