Hermann Thuswaldner 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: 5593534
    Abstract: According to the present invention, a web of material presenting periodic string parts, is provided with garnishing material by forming loops of garnishing material around the net yarn, and subsequently fastening the loops together, preferably by applying high frequency energy. This is preferably effected in an automatic machine, in which string parts together with accompanying garnishing are inserted into apertures formed on a drum by means of electrodes which are mutually separated during the process of insertion and which are then clamped together and supplied with high frequency energy, whereafter the electrodes are again separated to release the string material and garnishing.
    Type: Grant
    Filed: May 22, 1995
    Date of Patent: January 14, 1997
    Assignee: Barracuda Technologies AB

  • Patent number: 5285567
    Abstract: The invention relates to the joining of one web, e.g., of camouflage material to a carrier net or the like with the aid of fastener devices comprising male fastener parts (10) provided with pins or like elements which are hammered into complementary holes in female fastener parts (12). The female and male fastener parts are banded together by means of plastic wires moulded along the sides of the fastener parts and are separated subsequent to being brought to a fastener applying position (40) from a respective magazine (30,41). the male fastener parts are banded with the pins positioned in the direction of the band, while the holes provided in the female fastener parts face at right angles to the band direction. The bands are advanced by means of pawl-mechanisms (32-36 and 43-48) respectively). The invention relates to the banded fastener devices, a method of manufacturing the devices and a machine for applying the devices.
