Abstract

A calender apparatus for treating a traveling web having opposite first and second surfaces. The apparatus includes a roll which is supported for rotation about an axis and which provides a generally cylindrical outer surface. The apparatus also includes a shoe including a smooth calendering surface located in opposed facing relation to the outer surface of the roll. The web is directed between the outer surface and the shoe. The apparatus also includes a mechanism for urging the shoe toward the roll such that the calendering surface directly contacts the second surface of the web and urges the first surface of the web toward the outer surface of the roll.
