Abstract
In order to provide a device for the lateral scanning of napless areas of fabric webs which operates automatically with great accuracy and reliability even at high web speeds while being of relatively simple construction, it is proposed to cause the fabric web (7) to pass over a guide roller (11) and to cause the napless areas (9, 12) of the fabric web (7) to be scanned by means of photodetectors (2-6) consisting of transmitters and receivers, in which the scanning beams are directed tangentially to the guide roller (11) and thus to the fabric web (7) at its deflection point.
