Definitions
- the invention relates to a method and an apparatus for Production of a photographic material, one moving web-shaped underlay with one or more layers of liquid continuously coated and dried in a drying zone becomes.
- the base forms the layer support for the applied photosensitive recording layer of the photographic Materials.
- the recording layer is in usually multi-layer, is made of silver halide emulsion layers formed, which are usually covered by a protective layer.
- the Silver halide emulsion layers are by means of a Coating device, also referred to below as a caster, usually applied as a multi-liquid layer on the base.
- Production plants for the production of photographic films are operated continuously. The continuous Production process must be interrupted if that Coating machine is cleaned or when switching between various types of silver halide emulsions, briefly below Casting solutions, this requires.
- When making a photographic material is generally endeavored Keep production plant downtimes as short as possible.
- DE 26 48 574 is a production plant for manufacturing a photographic material known in which by means of a Switching device a change of casting solutions without Interruption of the casting process is possible. Doing so Plurality of castable casting solutions over a bundle of Pipelines supplied to the switching device, but only one Casting solution forwarded to the caster. The other casting solutions are kept in a cycle. When changing to another Casting solution a switching piston switches the new casting solution on Free pourer and recycle the remaining ones.
- test plants are not used in the Run, but operated discontinuously. They serve each a small amount of a new film for testing purposes to manufacture.
- the width of the film web is in a test facility usually about 20 to 30 cm, i.e. about 1/10 of the width of the Film track in a production facility.
- the coating device is designed for the discontinuous operation of the laboratory system. The Casting solutions do not become continuous but intermittent promoted.
- test facility for single or Multiple coating of a test loop known to be in one movable drying device is located.
- the loop will by means of several foundries arranged on a fixed casting table, in a chronologically defined sequence, coated with casting solution.
- the Positioning the respective caster in relation to the casting roller is done by gripping tongs and stops.
- a similar Test facility in which a closed loop is coated and the Loop is moved in the circumferential direction by a drying device, is known from EP 0 589 388.
- test facility is also described in DE 22 46 789. Also in this small laboratory system, an endless loop of a paper or Foil sheet coated by several coaters and in one Nozzle dryer dried. In contrast to the ones shown above The test casters are not stationary, but on one Rotary table movably arranged. During the operation of the The test facility can have several test casters, including those of different types to which the casting roll is placed.
- the invention is based on the object Production facilities for the production of a photographic material Downtimes caused by failure or cleaning of the Coating device and if necessary when changing the casting solution or caused by the caster to decrease.

- Coating device in a first step in operation in a coating zone Coating device is placed in a preparation zone.
- a second step is in a preparation zone ready-to-use foundry brought into the coating zone.
- This change is quick because the foundry used is immediately available. Interruptions in the production process, caused by cleaning work on the caster, can be short being held. Typical change times are in the range of a few to 20 minutes.
- a conventional one lasts Casting change, in which the casting device is mechanical only on site adjusted, connected to the delivery system and in operation there is taken, usually over an hour.
- the coating zone is the so-called casting room. Processing more sensitive to light Casting solutions take place under dark room conditions.
- Preparatory Working on the caster, such as maintenance, cleaning and in limited Extent of repair work is done in a so-called Preparation zone carried out under bright room conditions. It is recommended if these zones are in adjacent rooms and a change of coating equipment by implementing the in the Coating zone located coating device in the Preparation zone and one ready for operation in the preparation zone held coating device takes place in the coating zone.
- the change of the coating devices is preferred by a Implementation movement at least in sections along a Circular arc is carried out.
