Abstract

Apparatus and a method records a flaw in a fabric web during a flaw inspection. The flaw is recorded by a mark placed on the fabric web along with the X- and Y-values of a system of points defining a boundary line around the flaw. The mark and a side edge of the fabric web, respectively, serve as reference points for these X-and Y-values.
