ABSTRACT:
The developing machine includes a plurality of processing fluid stages arranged one after the other and a plurality of drying stages arranged one after the other. Film strips are guided along a predetermined winding path through the processing fluid stages and then through the drying stages. A pulling device located downstream of the most downstream one of the drying stations pulls film strips through the developing machine along the predetermined path. A control arrangement controls the operation of the pulling device in dependence upon the tension in film strips being pulled by the pulling device. The control arrangement includes a tension-sensing device operative for sensing the tension in film strips being pulled through the developing machine at a tension-sensing location intermediate the most downstream of the processing fluid stages and the most upstream of the drying stages.
