Abstract
A coating applicator system comprising a stationary coater blade, reciprocating valve and applicator plates and, interposed between the valve and applicator plates, a stationary metering plate which includes a metering cavity. In operation, a quantity of photoelectrophoretic imaging suspension is supplied to the metering cavity in the metering plate when the valve and applicator plates are cammed in. When the reciprocating plates are cammed out, a metered amount of the suspension is deposited on the coater blade and when the plates are cammed in the imaging suspension is caused to move into a coating gap to supply a uniform quantity of suspension to a surface to be coated.
