Abstract
Abstract Apparatus for supplying sheets to be printed to the plate cylinder of a multiple plate intaglio press, including means for changing the registration of successive sheets with the cylinder to correspond with variations in the positions of successive plates on the cylinder with respect to the sheet feeding means. The sheets move along an inclined feed board as they approach the first sheet transfer cylinder. The motion of each sheet is blocked by a movable stop means as it nears the end of the feed board. While the sheet is stopped, a set of grippers on the first sheet transfer cylinder engage the sheet at a location determined by the position of the stop means. The stop means is then retracted and the first and subsequent transfer cylinders then move the sheet along to the plate cylinder. The registry of the sheet with the plate cylinder is determined by the sheet blocking position of the stop means. The sheet blocking position of the stop means is shiftable and is shifted for successive sheets, to correspond to the differences in position of the successive plates on the plate cylinder. The sheet blocking position is shifted synchronously with the rotation of the plate cylinder, either in response to a pick-up unit which detects a certain angular position of the plate cylinder and operates the stop shifting means, or by a synchronous drive between the plate cylinder and a shaft on the stop shifting means.
