Abstract
A coating element has a liquid deflector member for diverting doctored coating liquid away from the surface of a coating applicator roll. The liquid deflector member is arranged beneath a blade member that removes excess coating liquid from the surface of the coating applicator roll. Excess coating liquid follows a path away from the coating applicator roll surface and down the active face of the liquid deflector member, thereby avoiding contamination of the applicator roll surface.
Claims9
An element for removing a film of excess liquid from the surface of a coating applicator and then diverting said film of excess liquid away from said surface, comprising:
- an element support member;
- blade member and a liquid deflector member, wherein said blade member having one end disposed in said element support member and an active end extending from said element support member for engaging said coating applicator, said blade member arranged at a predetermined angle θt with said coating applicator and having a point of contact therewith and wherein said liquid deflector member having one end disposed directly adjacent said one end of said blade member in said element support member and an opposite end with an active face, arranged proximate to said contact point of said blade member, extending downwardly and away from said blade member such that said active face is inclined at a predetermined angle θs relative to said active end of said blade member such that said predetermined angle θs is equal to or greater than said predetermined angle θt thereby resulting in the excess coating doctored by said blade member from said coating applicator being captured by said deflector member.
