Abstract
Abstract Apparatus for supplying sheets to be printed to the impression cylinder of an intaglio press, including a first sheet feeding cylinder for transferring sheets to the impression cylinder. The first sheet feeding cylinder is fixed on a shaft journaled on the ends of a pair of links, which are pivoted at their other ends for rotation about a fixed axis. A second sheet feeding cylinder and a gear are fixed on a shaft which rotates about that axis. The links are rotatably mounted on that shaft, which is driven in synchronism with the plate cylinder of the press. A gear fixed on that shaft meshes with another gear fixed on the shaft of the first sheet feeding cylinder. The links may be driven by a motor and appropriate gearing to swing the first sheet feeding cylinder between a printing position where it is in rolling contact with the impression cylinder and a retracted position where it is spaced from the impression cylinder far enough to allow access to the impression cylinder and the plate cylinder. Latches may be provided for holding the paper feed cylinder in either its printing position or its retracted position.

Total Claims: 26
Claim 1
Independent Claim
286 words
