OPERATING A PROCESSING MACHINE

Whether running tests or work the machine should be operated the same way. Provided all the checks have been carried out the drying cabinet heater can be turned on and the machine started.

  1. The replenishers should be turned on at leader rate.
  2. The free end of the machine leader is attached to the magazine leader.
  3. All joins must be checked to see that they are neat and the perforations "in rack" if the machine has sprockets.
  4. When the film reaches each bath, the replenishers are set to the specified rate.
  5. If sound application is necessary the applicator must be started before the film reaches it, and the operation of the bead checked as the film runs through.
  6. While the machine is running constant, vigilance is required. A general watch is kept on the running of the machine looking for build-up of tension or any other malfunctions. The following items should be continually monitored whilst the machine is running†: Drying Temperature Drying Humidity Bath Temperatures Replenishment rates Speed of the machine Correct operation of sound applicator
  7. As the films wind up on the dry end, the joins are removed and the film put in the correct can, the cans will be in the correct order.
  8. When the run is complete replenishers can be turned off, the drying cabinet turned off. If work is completed for the day, all other functions can be turned off after the film transport has been slackened.
