    摘要: A device for coating a material web includes a rotatable applicator roll having a surface for collecting a film of a coating composition thereon. The roll has a length defined by first and second ends thereof and a middle region disposed between the first and second ends. The device also includes a blade having an edge. The blade is attached to a blade holder and extends along the length of the applicator roll. The blade and the applicator roll surface form an acute angle and define a coating composition sump. The blade edge and the applicator roll surface define an inlet gap. A doctor element attached to a doctor element holder is disposed downstream of the blade with respect to a direction of rotation of the applicator roll. The blade, the blade holder, the doctor element, and the doctor element holder define, at least in part, an application chamber. At least one of the elements defining the application chamber has bores or other openings for regulating coating composition thickness on the applicator roll.
