摘要:
Disclosed is a process for the manufacture of a series of photoconductor webs spaced apart from each other on a carrier web by electrically conductive spacing strips extending transversely of the carrier web, comprising (a) transporting a carrier web having an electrically conductive surface disposed thereon in a feed direction across a backing member and in close proximity to a slot die arranged transversely to the feed direction; (b) pumping a photoconductive coating solution into the slot die; (c) flowing the photoconductive solution intermittently from the slot die orifice onto the carrier web for periods of time sufficient to produce the spaced photoconductor webs, the flow of the coating solution being substantially uniform during each coating period and the entire quantity of coating solution required for each coating photoconductor web being extruded from the slot die orifice in the form of a substantially uniform stream; (d) maintaining the distance between the carrier web and the die orifice constant and so small that the coating solution issuing from the die orifice forms a bridge between the orifice of the slot die and the carrier; and (e) drying the coated material. Also disclosed is an apparatus for carrying out the foregoing process.
