Coating method

摘要

An apparatus for applying silicone polymer coating to a web substrate comprising: a roll having a resilient surface; means to rotate the roll; a metering member comprising a hard, generally flat, elongated metallic strip having first and second polished edges with a relieved area therebetween to prevent engagement of the metering member with a metered film of liquid on the resilient roll surface except by the portion of the metering member lying between the first and second polished edges; means to urge the metering member into pressure indented relation with the resilient surface; and heat exchanger means adjacent the metering member to code the metering member adjacent the metering edge.
