Abstract:
A coating system and method including a web path moving a substrate past a contacting element including a distribution manifold having a cavity, and a multiplicity of needle tubes in fluid communication with the cavity, the needle tubes each having a needle tip dispensing a coating material towards a point of contact between the substrate and the contacting element. In some embodiments, the distribution manifold separates into a manifold containing the internal cavity, and a removable cartridge having the plurality of needle tubes. The coating system and method can be used to apply a pre-metered coating material to the substrate.
