Abstract
A paper machine includes a clothing carried by a plurality of rolls. At least one of the rolls is movable to exert a selected tension load on the clothing. The clothing includes auxetic fibers. By moving one of the rolls to exert a selected tension and/or press load on the clothing, a thickness of the auxetic fibers is modified to become thinner under a lesser load or thicker under a greater load.
Claims26
A paper machine clothing, comprising at least one layer of fibers, at least some of said fibers being auxetic fibers.
A paper machine, comprising a clothing carried by a plurality of rolls, at least one of said rolls being movable to exert a selected load on said clothing, said clothing including auxetic fibers which become thicker in cross section as said load increases.
A method of operating a paper machine, comprising the steps of:
- carrying a clothing with a plurality of rolls, said clothing including auxetic fibers;
- and
- moving one of said rolls to exert a selected load on said clothing, thereby modifying a thickness of said auxetic fibers to become one of thinner under a lesser load and thicker under a greater load.
