Abstract
A printing machine has a plurality of printing stations which print images on both major surfaces of each sheet passing through the printing machine. A reversing arrangement turns the respective sheet between two of the printing stations so that the major surface of the respective sheet having a fresh image thereon faces downwardly. A support arrangement is provided which supports this sheet during its advancement to the next following printing station, and includes a blow casing having upwardly oriented passages through which air issues in upward direction to create an air cushion between the respective sheet and the blow casing for supporting the respective sheet during its advancement. An elongated bracket is arranged upwardly of the blow casing and supports a region of the respective sheet which is devoid of the image, during the advancement of the sheet in a path portion located upwardly of the blow casing. The position of the bracket in the transverse direction of the machine is adjustable by means of a drive and a transmission which includes a transmission shaft having several sections interconnected by an elastic coupling. The blow casing is curved, and the number of the apertures per unit area within the curved portion and within the lateral portions of the blow casing exceeds that without such portions.
