Abstract
An apparatus for controlling the temperature of a recording material, in particular a printing plate, in an exposer for recording printing originals. An exposer has an exposure drum for holding the printing plate, and has a cylinder. An internal pipe and webs connect the cylinder to the internal pipe. Using a rotary lead-through, a temperature-control liquid is led into the internal tube of the exposure drum and, by thermal conduction via the webs and the cylinder, keeps the printing plate at a constant temperature.
Claims14
An apparatus for controlling a temperature of a recording material in an external drum exposer having an exposure drum for holding the recording material, the apparatus comprising:
- an internal pipe disposed on an axis of the exposure drum;
- and
- at least one rotary lead-through fluidically communicating with and through which a temperature-controlled liquid flows into said internal pipe.
An exposer for controlling a temperature of a recording material, comprising:
- an exposure drum for holding the recording material and having an axis;
- an internal pipe disposed along said axis of said exposure drum;
- and
- at least one rotary lead-through fluidically communicating with and through which a temperature-controlled liquid flows into said internal pipe.
An exposer for controlling a temperature of a recording material, comprising:
- an exposure body for holding the recording material and having an axis;
- an internal pipe disposed along said axis of said exposure body;
- and
- at least one rotary lead-through fluidically communicating with and through which a temperature-controlled liquid flows into said internal pipe.
An exposure drum for controlling a temperature of a recording material, comprising:
- cylindrical body for holding the recording material and having an axis;
- an internal pipe disposed along said axis of said cylindrical body;
- and
- at least one rotary lead-through fluidically communicating with and through which a temperature-controlled liquid flows into said internal pipe.
