Abstract: A processing apparatus such as may be used for photographic film in which the films passed through several different processing sections in succession with the tension of the film web maintained constant at all times.

The speed of conveyance of the web is increased in succession by driving the rollers at different speed or providing rollers of increasing diameter in the direction of the process outlet. One roller of each pair of rollers is provided with a stepped section having a height approximating the thickness of the web being conveyed. With this construction, a meandering correcting force is exerted on the web which overcomes the frictional force between the web and rollers thereby correcting any meandering of the web and maintaining the tension applied to the web at a value less than the strength of the web.
