ABSTRACT:
A method and an apparatus for fabricating gravure printing cylinders of synthetic resin in which a photosetting polyamide resin used as a solution of a coating resin is applied over the surface of a cylindrical base spirally as successively overlaid layers and thereafter the applied resin is subjected to drying by a heater and to photosetting by irradiation with ultraviolet rays, electron rays or the like. The resin layer surface thus obtained is mechanically engraved by an electronic engraver for forming gravure cells. The irradiation of ultraviolet ray, electron ray, or the like may be effected during or after application of the polyamide resin over the cylindrical base. The apparatus comprises a resin solution retainer closely adjacent to the cylindrical base. A substantially vertical lever pivoted for movement toward and away from the base supports the solution retainer. The lever may be moved by an element such as a motor-driven eccentric cam.
