Abstract
A roll coater can be modified by the addition of one or more needle tubes that supply coating fluid to the roll coater in discrete locations across the face of the coating roll. The needle tubes supply a localized band of coating material onto the coating roll superimposed over the uniform coating layer already present on the surface of the coating roll from an upstream coating pond creating a stripe pattern over the uniform coating layer. By varying the relative speeds of the coating rolls in the coater, the width of the stripe can also be adjusted.
