coating “with which the rollers are provided” would dig a notch or otherwise wear it. The use an intermediate metal roller to avoid the Deflection of roles in devices for. photographic treatment of films is too expensive.

Various attempts have been made to prevent the rollers from deflecting and over their whole Need to maintain a uniform contact pressure «For example, a roller squeezer is known, where the bearings are mounted on pegs " extending inward from the roll ends and carried by a continuous shaft. In paper and printing machines, catfish are usually rolls with sens? gg "Qssem diameter used" around the ratio Reduce the length to the diameter. For the Use in apparatus for photographic processing In films, however, such roles are too difficult and too difficult expensive.

The invention is based on the task of "one role" quetsch® to create »di® film strips up to about lloo mm Wide glelehmSssig squeezes and their roles easy and drifts for the purpose, "removed from purification can.

For the design of the roles in terms of their Weight and diameter apply as follows Considerations:

1 »If less material is used,

lower costs! 2. The rollers must be used for cleaning and maintenance can be taken regularly j 5. if the diameter is smaller, there is a smaller one There is a tendency that the opening or closing credits of the Film, which is passed between the rollers, rests on the periphery of a / rollers. "

The object is achieved according to the invention in that the first roller, which is long in relation to its diameter, is mounted with its ends facing away from each other in bearings fixed in the direction of loading, and that the second Role with their ends turned away from each other in lower right direction is movably mounted, a compared with the first role has a lower ratio between bending stiffness and weight and on the first Roll along a m & ntelllnle of old uniform contacts extending over the said effective roll length pressure is applied.

In order to achieve a uniform contact pressure between the So no attempt is made to get both roles.
