ABSTRACT:
A coating head assembly for applying a coating material to a web, comprises an applicator block; a paint reservoir defined in the applicator block for the storage of the coating material; and a generally elongated nozzle integral with the applicator block and extending in a direction substantially transverse to the direction of transportation of the web. A free edge of the nozzle opposite to the applicator block has a generally curved nozzle face. This nozzle face has a plurality of applicator grooves defined therein in communication with the paint reservoir. During the passage of the web in sliding contact with the nozzle face, the coating material is supplied outwardly from the applicator grooves for the transfer thereof onto the web, resulting in the formation of a striped pattern of the coated layer on the web.
