Perching

in the manufacture of textiles, the operation of examining woolen fabrics for imperfections. This work is done when the web is taken from the loom. The length of cloth is stretched in a frame and the percher examines it inch by inch, using a magnifying glass for the better grades of cloth. All knots and burs are carefully removed. If any holes are found they are neatly darned. The latter process is called burling.
