Apparatus and method for applying controlled patterns of liquid |
摘要 |
<p>An apparatus for dispensing a controlled pattern of liquid material, such as hot melt adhesive, includes a pump, a liquid applicator coupled to the pump, a pressure transducer located in the liquid path between the applicator and the pump and a controller coupled with the pressure transducer. The pump supplies liquid to the liquid applicator at a variable pressure. The pressure transducer detects the pressure of the liquid and produces a signal indicating a sensed pressure. The controller receives the signal and changes the pressure of the process air discharging from the applicator based on the received signal.</p> |
