Definitions

  • the procedure is generally such that the copying material is passed through a development space, at the bottom of which an evaporator is attached, into which a developer liquid is dripped, from which the developer gas is released by the action of heat .
  • the disadvantage is that part of the water vapor in the developer gas is deposited on the conveyor belt or the transport rollers and on the copying material.
  • the condensed water can moisten the copying material and detach the binder of the light-sensitive layer, as a result of which the copying material can stick to the components of the development space and faults can occur as a result.
  • the diazo copying material passes through an ammonia-water vapor mixture containing 3 to 25% by weight of ammonia at a temperature between about 105 ° to 120 ° C at atmospheric pressure.
  • the diazo copy material is exposed to a pre-development atmosphere at a temperature between 100 to 110 ° C which is 20 to 80% of the ammonia concentration of the developer gas atmosphere before the development atmosphere.
  • the device for carrying out this method comprises a development chamber which is equipped with at least one heating device which is connected via a temperature controller to a temperature sensor arranged in the development chamber.
  • the object of the invention is to improve a development process of the type described in the introduction in such a way that the working conditions are less expensive than with the known processes, that the condensate precipitation in the development space, the ammonia consumption and the ammonia content in the exhaust air are reduced and that the residual ammonia in the wastewater is expelled and fed to the development atmosphere.
  • the known device according to the preamble of claim 7 is used.
  • This device is designed according to the invention in such a way that the bottom zone of the evaporator is arranged below the evaporation chamber and can be heated by an additional heating device on the underside of the evaporator to a temperature less than or equal to the temperature in the development chamber and that the evaporator is connected to the development chamber via an evaporator tube stands and adjoins the wall of the development chamber in such a way that heat transfer takes place via the wall from the development chamber to the evaporator with a temperature drop of up to 5 ° C. from the development chamber to the evaporation chamber.
  • FIGS. 1 and 2 show a device for carrying out the method according to the invention, which essentially consists of a development chamber 1 and an evaporator 11 which is attached to the side thereof, as shown in section in FIG. 2.
  • the copying material enters the development chamber 1 through an input slot 8 and leaves it through an output slot 9.
  • the development chamber 1 is largely sealed off from the outside atmosphere by a driven pair of inlet rollers 21 and by a likewise driven pair of outlet rollers 3. With the inlet rollers 21 sealing lamellae 4 'interact with the outside atmosphere. Likewise, sealing lamellae 4 rest against the outlet rollers 3 and largely seal them from the external atmosphere.
  • the rollers 21 and 3 each consist of a metal core 22 which carries a coating 23 made of ammonia and heat-resistant silicone rubber.
  • This silicone rubber is largely resistant to ammonia and heat up to 170 ° C and has a considerably longer service life than the usual rubber compounds for such coverings, which decompose and harden after some time.
  • the sealing strips 4, 4 'consist for example, of 0.05 mm thick spring steel
