Abstract: A transfer device with which the hollow bodies to be printed in a printing machine may be transferred from a supply conveyor means to a capstan plate associated with the printing device. Since the hollow bodies are supplied by the supply conveyor means with a distance between them, which is smaller than the pitch of the receiving capstans of the capstan plate serving to accept the hollow bodies, a transfer rotor is placed in between, which possesses holding units, which perform the hollow body transfer as part of a pitch matching operation. A similar arrangement may also be employed to transfer already printed hollow bodies from the capstan plate to a removal conveyor means.
