Abstract
A first guide roll, a second guide roll and a backing roll are mounted on a movable frame. A feed roll is disposed substantially perpendicularly below the second guide roll upstream of the second guide roll relative to a direction of movement of a base sheet. The distance between the feed roll and the second guide roll is ninety (90) to two hundred and ten (210) times as long as a distance of travel of the backing roll when the backing roll is moved away from a coating roll.
