ABSTRACT:
The present invention relates to a web tension control device provided at a vertical drier for cloth webs, in which the cloth web is guided by means of conveyor means located in front of the lower cloth web inlet and after the lower cloth web outlet and by means of guide rollers provided in driven motion in the upper area of the drier. In order to detect without error the tension of the upward running cloth web, guide rollers 16, 17 are provided together with their common drive 18 on a rocker member 30 located outside the drier. The rocker member axis 30 is located immediately adjacent to the second guide roller 17 in running direction, while rocker member 30 is supported at the other end on a pressure cell 34 emitting a signal for the tension of the upward running cloth web.
