    means located downstream of said supplying means, including a transport path (19, 33,

         45) for changing the orientation of the leading edge of the sheet or sheet package as it is being received from a sheet supply means, moved within said transport path, and delivered to the sheet or sheet package removal means with changed orientation of a reference edge of the sheet or sheet package;

    comprisingtwo transport path guide rollers (20, 30,

         58) guiding said endless belt means in said transport path;

    a pair of superimposed endless gear belts looped about the transport path guide rollers;

    a pair of superimposed aligned plates or disks (4,

         5) movable;

    (a) away and towards each other to clamp the sheet, or sheet package between the disks or plates;

    (b) rotatably about an axis transverse to the major surface of the disks or plates (4,

    (c) conjointly with said endless gear belts (16,

         29) in said transport path;

    a cam means (23, 24,

         25) extending lengthwise of said transport path coupled to at least one of said disks or plates and controlling movement toward and away from each other as the disks or plates move in said transport path;

    the cam means controlling the respective position of the plates or disks with respect to each other for clamping and releasing the sheet or sheet package between the disks or plates;

    an upper shaft (21) to which the upper one (4) of the plates or disks is secured;

    and means for rotating the upper shaft (21) about a predetermined angle with respect to the transport path (45) to realign the reference edge of the sheet or sheet package, includinga gear (34);

    an endless gear belt (35) in engagement with said gear; and

    motor and rotation transmission means (37-42,

         36) in engagement with said gear belt to rotate the gear belt and hence impart rotation to the shaft and hence to the upper plate or disk (4) as the upper plate or disk is being moved in said transport path.
