Automatic processor for emulsion coated metal templates

Claim 1

In apparatus to develop sensitized emulsion coating on a metallic base sheet, the combination comprising: a. a sequence of sheet conveying rollers rotating to convey the sheet generally horizontally in a forward direction and with the coating exposed vertically, b. treating means to deliver and direct different liquids into contact with said coating at different stations during sheet forward conveyance, said treating means including header ducting having outlets directed at the path of sheet advancement through said stations, and a source of emulsion developer liquid in communication with said ducting at one of the stations, and a source of rinse liquid in communication with the ducting at at least one other station, there being means at subsequent stations to heat the sheet for drying same and to subsequently apply a protective layer over the emulsion, and means to direct narrow streams of air laterally across the emulsion side of the sheet prior to and following said subsequent stations, c. and multiple squeegees which are spaced in said direction to engage said coating during said conveyance and to confine said different liquids at said different stations during liquid contact with said coating, said squeegees comprising rollers defining the fore and aft limits of said different stations, and guide means guiding the squeegee rollers at opposite ends thereof to float vertically so that squeegee roller weight is imposed on the sheet and directly over certain conveying rollers.
