Process for preparing film strips for subsequent orders, the film strips belonging to a customer order. Each film strip includes a number of numbered masters which are fed into a preparation station. There, they are glued to a carrier belt and coiled into a film roll, which can be used at subsequent processing stations. Customer-specific order data regarding the desired number of copies of specific masters and, where applicable, the desired copy format, are entered via an input unit in the preparation station and stored onto a carrier medium which is compatible with the subsequent processing stations. In the process, the customer-specific order data are entered before the film strips are fed in. The fed-in film strips are automatically checked, before gluing to the carrier belt, for their position parallel to the conveyance direction and for the number order of the masters on the respective film strip, and by comparing with the customer-specific order data entered, it is checked whether the fed-in film strip is required for processing the customer order. If a film strip is improperly positioned or if a film strip is superfluous for processing the order, the operating personnel's attention is automatically drawn to the respective error, or the concerned film strip is automatically expelled before being glued to the carrier belt. A device according to the invention has an insertion area for the film strips which is equipped with at least one photoelectric sensor before a pair of draw-in rollers and which has, following the pair of draw-in rollers, a photoelectric scanner for the master numbers.

Process and device for preparing film strips for subsequent orders

A process and apparatus for processing strips of a photographic tape material whose surface is at least partially coated with, for example, an emulsion. In an exemplary embodiment, the apparatus includes means for determining the position of the side of the strip with the coated surface. In a first case, in which the side with the coated surface is in a desired position, a switch guides the unmodified strip onward for further processing. In a second case, in which the side with the coated surface is not in the desired position, the switch automatically guides the strip into a turning device before the strip is further processed.

Process and apparatus for processing strips of photographic tape material

A photographic printing machine for copying originals on sheet-like copy material having a storage reservoir for the copy material, and a feed mechanism which transports the copy material from the storage reservoir to an imaging unit in which the originals are copied onto the sheet-like copy material. The storage reservoir has numerous cassettes, the cassette openings of which are positioned side by side along a direction perpendicular to the transport direction of the copy material. The feed mechanism has a carriage that can move along the direction perpendicular to the transport direction of the copy material, for transporting the copy material from the respective cassette opening to the imaging unit.
