A sheet transfer drum for a rotary printing machine utilizes a plurality of sheet carrying segments which are axially adjustably positioned along a rotatable shaft. Each sheet carrying segment uses an upper bow and a lower bow with each bow, in turn, carrying a plurality of spaced sheet supporting elements. One of the sheet carrying bows is pivotable to actuate a cam-like fast acting closure or latch used to secure each sheet carrying segment to the shaft.
