Abstract: On a plant for continuous development of photographic material, comprising a plurality of operative units (6, 7, 8, 9, 10) for the photographic material treatment, there are provided a first and a second autonomous and independent adaptation units (12, 15), which can be interposed removably among these operative units so as to compensate the different photographic material advancement speeds between the one and the other unit, by controlling suitably the photographic material advancement devices of each adaptation unit and the operative units adjacent thereto. Advantages of the invention system include that the dangers of damagings and/or breakages of the photographic material are avoided during the advancement thereof among the various plant operating units and adaptation units, while promoting a rational and reliable arrangement and operation of the same plant.

Abstract: Transfer storage buffer apparatus for interconnecting processing machines for the development and printing of continuous-strip photographic material includes a plurality of rollers arranged on a fixed upper carriage and a movable lower carriage, respectively, at such positions that the material is alternately conveyed over the upper and lower rollers. The lower carriage is driven in both its upward and downward movement by an actuatable and adjustable elevating mechanism in the form of a pulley arrangement. The pulley arrangement includes a bracket sliding vertically on a fixed vertical support and locked to a flexible continuous-transmission element, and a lower pulley and an upper pulley over which the continuous-transmission element extends. A motor supplies power to the elevating mechanism to control the force under which the lower carriage is moved, to thereby regulate the tension on the photographic material.
