Abstract
At least one ribbon-like stream of a first coating composition adjacent to and in edge contact with at least one second ribbon-like stream of a second coating composition are deposited on the surface of a support member by establishing relative motion between the surface of the support member and the ribbon-like streams, simultaneously constraining and forming the ribbon-like streams parallel to and closely spaced from each other, contacting adjacent edges of the ribbon-like streams prior to applying the ribbon-like streams to the surface of the support member and thereafter applying the ribbon-like streams to the surface of the support member.
Claims9
A process for applying to a surface of a support member at least one ribbon-like stream of a first coating composition side-by-side to and in edge contact with at least one second ribbon-like stream of a second coating composition comprising providing a source for said ribbon-like streams, establishing relative motion between said surface of said support member and said source of said ribbon-like streams, simultaneously constraining and forming said ribbon-like streams parallel to, side-by-side to and spaced from each other, contacting adjacent edges of said ribbon-like streams prior to applying said ribbon-like streams to said surface of said support member, and continuously applying said ribbon-like streams to said surface of said support member whereby said ribbon-like streams extend in the direction of relative movement of said surface of said support member and said source of said ribbon-like streams to form a continuous unitary layer having a boundary between said side-by-side ribbon-like streams on said surface of said support member.
