A coater apparatus, for coating moving web, with fixed and movable lips

摘要

A coater apparatus (10) is disclosed for applying coating material onto a moving web. The apparatus (10) includes an applicator (16) having a first and a second end, the applicator (16) defining a feeding chamber (22) for the reception therein of the coating material (12). The applicator (16) includes a fixed lip (24) which extends from the feeding chamber (22) towards the web (14). A movable lip (26) extends from the feeding chamber (22) such that when the movable lip (26) is disposed in a first disposition thereof, the movable lip (26) cooperates with the fixed lip (24) for defining therebetween a slot for guiding the coating material (12) from the feeding chamber (22) towards the moving web (14). However, when the movable lip (26) is pivoted away from the fixed lip (24) to a second and third disposition thereof, flushing and cleaning of the applicator (16) is permitted.
