Abstract
A portable coating apparatus is described for use with a paper converting machine such as a corrugated paperboard double-backer. Rotational power to drive gravure, transfer and smoothing rolls is extracted from the converting machine supply web by an S-wrap through the loaded nip between a pair of drive rolls. A low-powered auxiliary drive motor is automatically engaged to keep the gravure and transfer rolls conditioned with coating during brief intervals of web feed cessation. The entire unit is constructed on a space frame that is supported by caster wheels to facilitate movement to and from an appropriate converting machine position which may be between the reeled web supply unwind stand and a web preheating drum station leading into a double-backing machine.
