ABSTRACT:
A flow coat head for curtain coating, particularly of sheet material, employing a container for the coating material having a pair of end walls connected by an elongated tubularly-shaped body, provided with an elongated longitudinally extending slot in the wall thereof which forms the material discharge opening of the head, and extends continuously from one end of the body to the other, with the body wall peripherally extending continuously from one of its longitudinal slot edges to the other thereof, forming a slot having a transverse width at least equal to the maximum desired operating width of the material discharged, pressure being applied on said body member at opposite sides of the slot in directions to move the edges of the latter toward one another and thereby vary the effective discharge width of the slot.
