ABSTRACT:
In a web-coating apparatus a web moving continuously in a travel direction passes in a contact arc partially around a cylindrical surface of a backing roller centered on an axis. An applicator system has an applicator roller extending parallel to the backing roller, having a smooth cylindrical outer surface, and forming a gap with the backing roller. The web passes through the gap. A substantially stationary support extends generally parallel to the backing roll axis across a full width of the web and a pusher element limitedly movable generally radially toward and away from the backing-roller axis on the support bears radially of the backing-roller axis on the applicator roller along the full width of the web. An inflatable hose between the pusher element and the support along the full width of the web urges the element and applicator roller toward the backing roller. A coating liquid is supplied to the gap across the full width of the web.
