The invention provides an apparatus for conveying a pile of photosensitive printing plates in which a support is covered thereon with photosensitive resin. The apparatus comprises a base plate and a pair of end plates for holding the pile of photosensitive printing plates therebetween. The pair of end plates is vertically mounted on the base plate so that the pile of photosensitive printing plates is vertically held between the pair of end plates on the base plate.

Apparatus for conveying presensitized lithographic printing plates

A position setting apparatus for positioning a drum so that it may be uniformly coated with a photosensitive coating liquid to produce a photoreceptor, wherein the position of the drum is set by centripetally blowing a pressurized fluid from a fluid outlet means directly against the drum. The drum is positioned by the balance of the pressure of the blown fluid, and the surface of the drum is thereby protected from scratching as no mechanical device is required to touch the drum during positioning.

Photoreceptor-drum-positioning apparatus

A method of coating a first resin solution containing a polymerization inducer on a moving web-like support with a coating device, comprising conveying the support to pass near the coating device without coming in contact with the coating device, disposing the first resin solution in a form of a first resin solution layer from the coating device onto the support; the first resin solution layer having a lower surface which faces the support and an upper surface opposite to the lower surface; and the coating device having a first release point at which the upper surface leaves the coating device and a second release point at which the lower surface leaves the coating device; overlaying the first release point with a solvent, thereby superimposing a solvent layer on the upper surface of the first resin solution layer; overlaying the second release point with a second resin solution which does not contain a polymerization inducer, thereby superimposing a second resin solution layer on the lower surface of the first resin solution layer; and applying the superimposed layers onto the support so that the solvent layer forms an uppermost layer on the support.
