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.

Element for deflecting excess liquid from a coating surface

An apparatus for coating a web of indeterminate length has a coating element comprising a liquid deflector member for diverting liquid away from a coating surface. The liquid deflector member is arranged beneath a blade member that removes excess coating liquid from the coating surface. Excess coating liquid follows a path away from the coating surface and down the liquid deflector member thereby avoiding contamination of the coating surface.

Apparatus for coating a web

The present invention is a method of providing an imaging element which includes providing a gravure cylinder having an outer surface having a plurality cells. The surface of the cylinder is moved through a coating solution of a film forming organic polymer to fill the cells with coating solution. An imaging element is moved across the outer surface of the gravure cylinder to deposit the coating solution onto the imaging element such that a fraction of the imaging element of from 0.02 to 0.98 remains uncovered with coating solution. The coating solution is dried to form a discontinuous overcoat on the imaging element.

Method of forming a discontinuous polymer overcoat for imaging elements

The present invention is an imaging element which includes a support, an imaging layer superposed on a side of said support and an overcoat overlying the imaging layer. The overcoat is composed of an organic polymer. The overcoat is discontinuous such that a fraction of the surface area of the imaging layer remains uncovered by said polymer, wherein the fraction of area not covered by the said polymer is from 0.02 to 0.98. The present invention is a photographic which includes a support, a silver halide emulsion layer superposed on a side of said support and an overcoat overlying the silver halide layer. The overcoat is composed of an organic polymer. The overcoat is discontinuous such that a fraction of the surface area of the silver halide emulsion layer remains uncovered by said polymer, wherein the fraction of area not covered by the said polymer is from 0.02 to 0.98. In one embodiment, the discontinuous overcoat is a series of parallel stripes.

A coating feed apparatus and method (,) for depositing a uniform overflow curtain-like layer of coating composition (c) to a gravure surface (,) has a reservoir (,) and means for delivering the coating composition to the gravure surface (,). The reservoir (,) has a base (,) sloped upwardly from a rear wall (,). A widthwise lip (,) is directed generally downwardly towards the gravure surface (,). Widthwise lip (,) and the undercut portion (,) together enable the coating composition (c) exiting the outlet end (,) of the reservoir (,) to overflow downwardly across widthwise lip (,) in a uniform curtain-like layer (,) towards the gravure surface (,) without creating a backflow of coating composition along the base (,).

Curtain feed method for a gravure process

An apparatus for coating surfaces consists of a basin, open to the atmosphere, divided into two channels by a wall running perpendicular to the coating direction. Liquid is supplied to the primary channel, the channel farther from the curtain. A continuous, adjustable gap between the dividing wall and the bottom of the basin offers resistance to flow but passes the coating composition from the primary to the secondary channel. The secondary channel has an edge that is horizontal and relatively low so that the coating composition overflows it to form a free-falling curtain. The dividing wall, by providing flow resistance, assists in distributing the supplied coating composition along the length of the primary channel, and reduces any flow disturbances caused by the entering coating composition. The secondary channel promotes additional evening of the flow distribution before the curtain forms.

Coating surfaces with a free falling coating composition, using a basin

A coating feed apparatus and method (10) for depositing a uniform overflow curtain-like layer of coating composition (c) to a gravure surface (14) has a reservoir (14) and means for delivering the coating composition to the gravure surface (14). The reservoir (14) has a base (24) sloped upwardly from a rear wall (22). A widthwise lip (40) is directed generally downwardly towards the gravure surface (14). Widthwise lip (40) and the undercut portion (48) together enable the coating composition (c) exiting the outlet end (26) of the reservoir (12) to overflow downwardly across widthwise lip (40) in a uniform curtain-like layer (32) towards the gravure surface (14) without creating a backflow of coating composition along the base (24).

Gravure coating feed apparatus

An apparatus to apply a uniform coating to a gravure cylinder for imprinting upon a second surface, typically a web, is disclosed herein. The apparatus includes a feed bar, which controls the flow of the coating solution, and a supply box, which includes end dams, an overflow port, and a reservoir created by a baffle. With the overflow port and baffles a uniform coating of a composition is achieved without imperfections created by evaporation or foreign matter.
