Abstract
143,623. Pickup, W. Feb. 25, 1919. Intaglio-plate printing; tripping-arrangements.-In a rotary photogravure printing - machine of the kind in which the printing-cylinder is moved by cam and link mechanism out of contact with the impression cylinder throughout every alternate revolution, the sheets are fed between the printing and impression cylinders by a horizontally reciprocating feedtable and, after being printed, pass between a pair of guides to a pair of delivery tapes. The printing-cylinder a is mounted in vertically slidable bearings b to which are pivoted vertical links o engaging two cams m on a driving-shaft n which makes one revolution for every two revolutions of the cylinder a, so that the cylinder a is slightly out of contact with the impression cylinder e throughout every alternate revolution, providing time for the insertion of the sheet between the cylinders a, e and dispensing with the use of grippers. The sheet is laid against guides l on a table h which is reciprocated on rails k by a link y and bell-crank x operated by a cam u on the shaft n, carrying the sheet forward till its front end is just beyond the line of contact of the cylinders a, e. The cylinder a is then raised by the cams m, and the sheet is printed and carried forward between steel guides z, 2 to tapes 3 which deposit the sheet printed-side-up on a delivery board 4. The machine is particularly applicable for printing sheets several times in different colours, the several impressions registering accurately with each other.
