Abstract: An insert for paper processors with containers for liquids which are arranged in a working direction one behind the other, whereby each insert includes a rotary endless conveyor belt as means of transportation for photographic material. The conveyor belt extends beyond the width of carrier rollers which are arranged in pairs on the input side and on the output side of the insert, whereby the pair of carrier rollers on the output side constitutes a first squeeze station, since one of these carrier rollers works as a squeeze roller. In addition to the first squeeze station, there is provided a second squeeze station which is adjacent to the first squeeze station.
