Abstract
A method and apparatus for high speed application of sizing compositions in which there is a pair of oppositely rotating rolls forming a coating nip therebetween through which a paper web to be sized is directed. Sizing composition is delivered to the nip in sufficient quantity to form a pond of sizing composition above the nip. The invention is particularly concerned with reducing the effects of translational energy which is transmitted into the pond from the rolls by providing at least one flexible baffle member which extends into the pond on opposite sides of the paper web into proximity with the nip. The baffle member should be sufficiently long to absorb translational energy which would otherwise be absorbed by the pond of sizing material.
