ABSTRACT:
Methods for operating a material dispensing system. The method includes measuring numerical values of an operating parameter, such as line velocity, material pressure, or material temperature, of the dispensing system to predict a future numerical value of the operating parameter. The predicted numerical value of the operating parameter is used to accurately define a start time, which is measured from the detection of the presence of a workpiece being transported past an applicator of the dispensing system, at which to initiate dispensing of the material from the applicator. A calibration procedure is provided for deriving a mathematical relationship used to determine the predicted numerical value of the operating parameter.
