Abstract
A coater assembly includes an array of side-by-side selectively closable slot portions to control pressurized fluid flow onto a substrate during relative movement between the coater assembly and the substrate to form a coating pattern on the substrate. A control module produces the coating pattern via control over selective independent closure of the slot portions based on a mapping matrix of individually addressable coatable elements.
Claims15
A coating system comprising:
- a coater assembly including:
- a first portion to contain a pressurized volume of fluid;
- and
- a second portion including a linear array of side-by-side selectively closable slot portions to control pressurized fluid flow from the first portion via each respective slot portion onto a substrate during relative movement between the coater assembly and the substrate, the array extending in a first orientation generally transverse to a substrate advance direction;
- and
- a control module to control selective independent closure of the slot portions to form on the substrate a coating pattern via a mapping matrix of individually addressable uniformly-sized coatable elements.
A method of manufacturing comprising:
- arranging a coater assembly to include:
- a first portion to contain a pressurized volume of fluid;
- and
- a second portion includes a linear array of selectively closable slot portions, each in communication with the first portion and the array extending along a length of the first portion and positioned adjacent a substrate support for pressurized fluid flow selectively through the respective slot portions onto a substrate, the coater assembly and the substrate support being movable relative to each other;
- and
- coupling a controller to the coater assembly to enable mapping a coating pattern according to individually selectable coatable portions and noncoatable portions and producing the mapped coating pattern via selective independent opening and closure of the slot portions.
A computer software product comprising a non-transitory tangible medium storing a set of instructions for operating a coater assembly that includes independently controllable slot portions arranged in series transverse to a media advance direction and in coating relation to a media, the instructions comprising a set of instructions which, when loaded into a memory and executed by a processor, causes selective independent closure of the slot portions to form on the substrate a coating pattern via a mapping matrix of individually selectable coatable elements.
