A process for producing paper webs having a pattern formed into the web is
disclosed. The pattern is formed during formation of the web and is made
by varying the basis weight of the web. The paper web is produced by
depositing an aqueous suspension of fibers between two forming surfaces.
One or both of the forming surfaces include lower permeability areas that
create lower basis weight areas in the web. The lower permeability areas
are contained in the forming surface according to a particular pattern.
For instance, the lower permeability areas can be formed into a drainage
roll sleeve contained on a drainage roll which contacts a forming
surface. The drainage roll can be a forming roll or a breast roll.
