Zusammenfassung:	Methods and apparatuses for forming fibrous web structures are disclosed. In one embodiment, a method of forming a fibrous web comprises positioning a masking media over a foraminous forming member having a forming surface, the masking media producing covered portions and uncovered portions of the forming surface, applying vacuum pressure so as to draw air through the forming surface, depositing fibrous material onto the forming surface to form a fibrous web. The masking media may be flexible such that the at least one masking media is sucked tight to the forming surface and forms direct contact with the forming surface where vacuum pressure is applied, thereby preventing the fibrous material from flowing between the at least one masking media and the forming surface.
