LIQUID COATING APPARATUS AND SYSTEM FOR CLEANING ROTARY COATING APPLICATOR THEREOF WITHOUT INTERRUPTION OF COATING PROCESS

摘要

A resin application apparatus used in the production of oriented strand board hasa rotary atomizer supported within a drum for containing and tumbling wood flakes. Aspinning cup is rotatably supported by a housing of the atomized, with a gap formedbetween an outer surface of the cup and the housing. A supply line provides resin to thespinning cup for atomization thereof and coating of the tumbling wood flakes. Apassageway is formed in the housing terminating in an outlet proximate the spinning cup.Solvent is flowed through the passageway and out of the outlet, sweeping away anyaccumulated material in the gap and on the spinning cup and housing. The cleaningoperation is performed simultaneous with the flow and atomization of the resin, wherebythe resin application process continues without interruption.
