ABSTRACT:
Uniform embossing on both sides of a web of paper may be obtained in a single pass through an embossing nip by interposing a thin film of tough, resilient material in the form of a continuous belt of approximately 0.050 inch thickness or less between the embossing roll and the backup roll. Stationary guide members, which may be combined with air bearings, are provided to insure proper tracking of the belt.
