ABSTRACT:
A device for regulating the tension of a travelling web moved as a result of the application of traction includes a roller freely rotatable about its axis arranged transversely with respect to the direction of web travel. This roller is in contact with one side of the web and deflects the latter upstream of the traction means. A spindle of the roller is supported at each end by a support which allows a movement of the end in a direction substantially perpendicular to the web, by applying to the end, in this direction and towards the web, a predetermined force which is identical from one support to the other and is constant, whatever the position of the end. The device applies tension over the length and width of the web such as a paper web as is used in the corrugated cardboard industry.
