upon the properties desired the fabric 10 is shown as having a plain weave however it will be recognized by those skilled in the art for under present disclosure that the weave can be any desired weave such as a crows foot or sateen if desired referring now to fig2 a portion of a second embodiment of a papermaking fabric 20 is shown the fabric 20 includes machine direction yarns 22 and cross machine direction yarns 24 the cross machine direction yarns 24 are preferably i beam shaped yarns having the central web oriented generally horizontally this provides a fabric with increased strength stiffness and a lower caliper the machine direction yarns 22 are shown as monofilaments having a circular cross section however it will be recognized by those skilled in the art from the present disclosure that the machine direction yarns 22 could have any other desired cross sectional shape depending upon the properties desired preferably the machine direction and cross machine direction yarns 22 24 are extruded in the known manner referring now to fig3 a portion of a third embodiment of a papermaking fabric 30 is shown the fabric 30 includes machine direction yarns 32 and cross machine direction yarns 34 preferably both the machine and cross machine direction yarns 32 and 34 have a generally boxed shaped cross section with a hollow center this construction provides good contact area and stiffness in the lateral and vertical directions to provide a high stability high contact fabric having a low mass due to the use of hollow yarns 32 34 the box beam configuration also provides exceptional torsion resistance in order to maintain excellent fabric dimensional stability while the portion of fabric shown has a two over two under weave it will be recognized by those.
