A fixing device for a wet type master sheet making apparatus for making a master sheet has a heated panel for fixing and drying a developed image on the master sheet while the master sheet moves on the panel, and a cleaning web placed between a surface of the panel and the master sheet to absorb extra developing liquid on the master sheet while the master sheet moves on the panel. The fixing device has web winding means for winding the web to move the web along the surface of the panel, and actuating means for selectively actuating the winding means by one of manual and electrical operations. Therefore, the user can easily and quickly tension the cleaning web to make the cleaning web tightly contact the surface of the panel by manually actuating the winding means when the cleaning web is replaced.

Fixing device for wet type master sheet making apparatus for making

A fixing apparatus for a wet-type plate making machine, which includes panel heaters 13 and 14 for fixation and drying of an electrostatic latent image an a front surface of a master X after development with developing solution and a cleaning web 20 that is laid over top surfaces of the aforenamed panel heaters 13 and 14 and that will be wound around a web take-up bobbin 20B that is disposed at an end of the same panel heater 14, and which also includes a web take-up shaft 27 that has a bobbin attachment and 27a for supporting of the aforenamed web take-up bobbin 20B and a manual operation end 27b that can be turned freely with finger tips, a first one way clutch 31 that is fitted on the take-up shaft 27 and that transmits revolving movements of a clutch sleeve 31a that is reciprocally revolved by a solenoid 29 at the apparatus securing part but transmits only those in one direction to the aforenamed take-up shaft 27, and a second one way clutch 36 that in fitted on the take-up shaft 27 and that allows forced revolving movements of the aforenamed take-up shaft 27 in a taking-up direction by the aforenamed manual operation end 27b.
