Abstract
As textile fabric is spread from a roll onto a cutting table, in stacked layers, the cutting pattern is selectively projected by the apparatus of the invention onto the unrolled fabric wherever a fabric flaw is known to exist to enable the operator to determine, prior to attaching a corresponding paper pattern to the spread fabric, whether or not the flaw will otherwise be present in an area to be cut out according to the pattern. The pattern projecting apparatus is mechanically and electronically coordinated with the fabric spreading apparatus and as the projecting apparatus scans across the width of the unrolled fabric, the projected image appears to the operator to be stationary on the fabric and is properly located longitudinally and transversely on the fabric with respect to the pattern which is ultimately to be cut out.
