Abstract

A heated backing roll is disclosed for cooperation with an elongate shoe for defining therebetween an extended pressing section for the passage therethrough of a web. The roll apparatus includes a rotatable, cylindrical body which defines a circumferential outer surface. A coating is applied to the outer surface of the body such that the coating is disposed in pressing contact with the web during the passage of the web through the pressing section. The coating has properties which inhibit sticking of the web to the coating subsequent to the passage of the web through the pressing section. The coating includes a mixture of chromium and TEFLON.
