ABSTRACT:
A method and apparatus for limiting the width of a coating and/or preventing damage to roll ends while coating or surface-sizing paper or an equivalent web material in a coating device in which a coating agent, such as size, coating paste or equivalent, is introduced into the coating device to an application zone defined by a coating member, a moving base, lateral seals, and a front wall and spread onto the moving base by the coating member which is loaded against the moving base. Liquid jets are sprayed into the areas outside the coating width, substantially over the width defined by the lateral seals and the roll ends, either onto the moving base before the coating member in the running direction of the moving base or directly into the nip formed by the moving base and the coating member. The liquid jets lubricate the nip and dilute the coating agent that has entered into the areas outside the coating width. The excess amount of the sprayed liquid is collected and removed to prevent entry of the excess amount of the sprayed liquid into a recirculation system the coating agent and prevent the coating agent from being diluted.
