Disclosed is an apparatus for properly orienting a thin flexible lighographic master sheet prior to the master sheet being fed to and clamped onto the master sheet cylinder of a lithographic press. The apparatus is basically a flat tray with movable pushers mounted thereon for shifting a sheet deposited on the tray in a lateral direction with respect to the direction of travel of the sheet and also longitudinally along the direction of travel of the sheet in order to place the sheet in a precise predetermined position with respect to a take-away mechanism. The apparatus also includes a movable wire guide device which maintains the sheet in a flat condition while it is being oriented to prevent the sheet from buckling more than the very slight degree which is specifically provided for to assure proper orientation. The device is constructed to be self-powered and readily removable from the duplicating machine with which it is normally associated.
