Beschreibung
Zusammenfassung:	The invention provides woven papermaking fabrics having a machine direction (MD) axis and a cross-machine direction (CD) axis, a machine contacting surface and a sheet contacting surface where the sheet contacting surface comprises a plurality of twill woven protuberances defining valleys there between. Generally the protuberances are skewed relative to a principle axis of the fabric, such as the MD axis and have a non-zero element angle. The protuberances generally have an upper surface defining the upper most surface plane of the web contacting surface of the fabric. Further, the protuberance upper surface is substantially planar providing the protuberances with a height that is substantially constant along the length of the protuberance.
