See also patents for making wire-sieves. One of the most important uses of wire-cloth is for the webs in paper-making machines. These have from 2,300 to 6,400 meshes to the square inch. They are woven in lengths of 30 to 40 feet, the widths varying from 4 to 10 feet, and their ends are joined together so as to form endless bands, known as paper-machine wire. Wire of sufficient fineness can, however, be woven so as to have over 19,000 perforations or holes to the square inch. Sieves of th
