The substrate is carried through the roll coating machine on a belt conveyor. A pool of coating liquid is contained between the coating roll, doctor roll and end sealing plates. The coating roll, the doctor roll and the conveyor are individually driven at variable speed, adjustable for best performance of the machine. The adjustment for substrate thickness is easily done by motorized screw lifting of roll assembly. The coating liquid level between the coating and doctor roll is adjustable and automatically controlled by ultrasonic sensor. The thickness of coating is accurately controlled, providing a uniform coverage on the product.
