  • System and method for active adhesive recirculation control
    Patent number: 11344909
    Abstract: A method for controlling a recirculation pump assembly is disclosed. The method includes receiving a process-dependent characteristic and determining a recirculation flow rate of adhesive that flows to the recirculation pump assembly based on the process-dependent characteristic. The method further includes determining a recirculation pump speed of the recirculation pump assembly for pumping the adhesive to a supply channel using the recirculation flow rate, and adjusting an operating speed of the recirculation pump assembly to match the recirculation pump speed. A system and storage device for performing the above method are also disclosed.
    Type: Grant
    Filed: July 22, 2020
    Date of Patent: May 31, 2022
    Assignee: Nordson Corporation
    Inventors: Joel E. Saine, John W. Fritz
