  • Method and device for applying portions of adhesive
    Patent number: 12569873
    Abstract: A method for applying individual portions of adhesive to a substrate, in which the portions of adhesive are applied successively by means of a valve, a coil of an electromagnet being energized with an actuation voltage pulse for each successive dispensing of portions of adhesive from the valve, which causes a valve opening of the valve for an actual opening duration during which adhesive can flow out of the valve for dispensing the respective adhesive portion by moving a closure member of the valve from a closed position into an open position. The actual opening duration of at least one valve opening which follows a valve opening which precedes it in time is shortened in accordance with one or more valve operating parameters to compensate for electromagnetic interference effects which extend the actual opening duration of the subsequent valve opening.
