  • RF welding device with filtering and tuning
    Patent number: 7586071
    Abstract: An RF welder, and a method of operation thereof, is disclosed that has circuitry that automatically affects system impedance so that, throughout the welding or embossing cycle, a generator is capable of delivering the same power to a die and fabric, and cabling is capable of dissipating a load that is less than a preselected amount.
    Type: Grant
    Filed: May 22, 2007
    Date of Patent: September 8, 2009
    Inventors: Mark Gruenspecht, Timothy Hopper
