Paper machine fabric with trapezoidal shaped filaments
摘要:
A fabric for use on a paper machine includes a plurality of filaments woven together. At least a portion of the filaments have a generally flat machine side base, a generally flat web side face, and a pair of generally flat side walls extending between the base and the face. The portion of the filaments having a generally trapezoidal shaped cross section is defined by the base, the face and the pair of side walls.
