  • Positive feed system for wallboard tape applicators
    Patent number: 5230608
    Abstract: Wallboard compound is fed by gravity from a reservoir to the inlet of a positive displacement pump which pressurizes the compound and feeds it to a wallboard taping applicator. The pressure of the compound fed to the applicator is controlled within predetermined limits so as to provide an even and near instantaneous flow of compound to the applicator.

  • Applicator for wallboard tape
    Patent number: 4775442
    Abstract: An apparatus for dispensing wallboard tape and wallboard compound is provided with a nozzle which applies the compound through a series of opposed feed channels. Each feed channel applies a bead of compound to one side of the tape as the tape passes through the nozzle in a longitudinally folded condition. Upon exiting the nozzle the tape is unfolded and the compound is uniformly extruded beneath the tape. Venting grooves extend from the feed channels to the nozzle exit to prevent clogging of the feed channels by the tape.
