Abstract:
A method of screening an article with a dual reservoir dispensing assembly comprising a first reservoir for holding a first material to be dispensed; a first nozzle in communication with the first reservoir wherein upon a predetermined command, the first material in the first reservoir is dispensed through the first nozzle; a second reservoir for holding a second material to be dispensed; a second nozzle in communication with the second reservoir wherein upon a predetermined command, the second material in the second reservoir is dispensed through the second nozzle; a tilt means for tilting the nozzles, wherein upon a first predetermined command, the tilt means tilting the nozzles in a first direction so that the first nozzle is tilted into position for dispensing the first material, wherein upon a second predetermined command, the tilt means tilting the nozzles in a second direction so that the first nozzle is tilted out of position and the second nozzle is tilted into position for dispensing the second material, the method comprising the steps of:placing an article to be screened onto a table;placing a dual reservoir dispensing assembly into a starting position;tilting the nozzles so that the first nozzle is tilted into position for dispensing a first material;traversing the dual reservoir dispensing assembly across the article to be screened in a first direction while dispensing a first material onto the article;tilting the nozzles so that the second nozzle is tilted into position for dispensing a second material; andtraversing the dual reservoir dispensing assembly across the article to be screened in a second direction while dispensing a second material onto the article.
