Orientation line in an endless travelling web.

摘要

In a machine cloth (1) is disposed an orientation line (3) which extends in the crosswise direction of the cloth. The configuration of the orientation line (3) is sensed by sensors (4) and is displayed on a screen (6) so that distortions or deviations in the machine cloth (1) becomes visible to the operators who may rapidly take measures to correct the incorrect position of the machine cloth (1).
