Abstract

The machine has a fixed support on which there are mounted a device printing the sensitive sheet using a source of actinic light, an insertion and slide track for the sensitive sheet, a motor-driven sheet driving roller downstream of the printing device, and a thermostat controlling the temperature of the heat source. The latter (12) is mounted outside the roller (1) driving the sheet (2), close to the emulsioned face of the sheet and along the path it travels after printing, so as to reheat and develope it. The source can be in the form of an electrical resistance, there being a cloth of electrically insulating material between it and the sheet.
