Abstract:
Apparatus for coating a web of indeterminate length, comprising:a source of coating composition; an engraved cylinder at least partially in fluid contact with said source of coating composition, said engraved cylinder having a plurality of cells for collecting coating composition therein and then transferring said coating composition to said web of indeterminate length; an impression cylinder in rotating contact with said engraved cylinder, said impression cylinder and said engraved cylinder forming a web transfer path therebetween; means for advancing said web of indeterminate length through said web transfer path so that coating composition in said plurality of cells transfers to said web of indeterminate length forming an applied coat of coating composition on said web of indeterminate length; and, a coating element arranged in an upper region and along a circumferential portion of the engraved cylinder proximate to a dead center point on the engraved cylinder, said coating element comprising a blade member and a liquid deflector member, wherein said blade member having one end disposed in an element support member and an active end extending from said element support member for engaging said engraved cylinder, said blade member being arranged at a predetermined angle &thgr;t with said engraved cylinder 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 &thgr;s relative to said active end of said blade member such that said predetermined angle &thgr;s is equal to or greater than said predetermined angle &thgr;t thereby resulting in the excess coating doctored by said blade member from said engraved cylinder being captured by said deflector member.
