ABSTRACT:
A gas wiping die is provided with a predetermined arrangement of cams which act against a flexible lip either directly or through intermediate push rods or the like to adjust the opening of the wiping die orifice. The invention may involve several cam shafts which may be rotated by a so-called stepping motor or motors. The arrangement allows a smooth progression of changes in the opening and camber of the coating die gas orifice slot. Various contours of cam shaft may be provided to provide easily implemented programs of die adjustment, either smoothly or discretely, to adjust for variations in coating conditions or procedure.
