Machine for simultaneously making two printing plates for newspaper printing

摘要

A news-printing photoengraving machine of this invention increases photoengraving speed without unduly increasing size or manufacturing costs of a CPT-type photoengraving machine by decreasing waiting time for form plates transferred from a plate feed section. The machine comprises a plate feed section, an exposure section, a plate discharge section, and a development section to make a drawing on a form plate at the exposure section in accordance with a signal output from a computer. The form-plate feed section has a stocker case for storing form plates and a transfer unit set above the stocker case to be vertically movable for transferring form plates along a guide rail. The exposure section has at least two exposure barrels arranged at intervals, a laser-beam scanning head, a first table on a side of each exposure barrel toward the form-plate feed section, and a second table on a development-section side of each exposure barrels. The plate discharge section has a discharge table on an exposure- section side of the development section.
