Abstract

1436043 Web feeding &c. CHAMBON Ltd 11 Jan 1974 [11 Jan 1973] 01398/74 Heading B8R A web tensioning device in an apparatus comprising a pair of upstream rollers A and a pair of downstream rollers B includes a drum 7c disposed between the rollers A, B and supporting over part of its periphery a web 4, the drum being associated on diametrically opposite sides with a pair of dancer rollers 7b, 9b mounted on levers 7d, 9d, for independent rotation about the shown axis, whereby the roller 7d which is biased by a weight 8 is displaced by the web on variation of web tension and causes a device 12 to actuate the dancer roller 9b such that the levers 7d, 9d are always forming an extension of one another. Arrangement of levers maintains web tension and length constant. In addition the lever 9d, which is coupled to a second arm 9e controlling a speed regulator 10 for a roller 1 of the first pair of rollers A, controls also the speed regulator 10 in response to induced movement by the dancer roller 7b.
