Abstract
A printing assembly for a printing machine comprises a drum mounted for rotary movement about an axis and supporting a plurality of object holders parallel to the drum axis and uniformly circumferentially spaced around the axis. A drum drive imparts continuous rotary movement. A printing station at the periphery of drum for printing successive objects in the course of displacement by the printing station. The printing station is carried by a beam and includes a screen and squeegee. A beam drive is synchronized with the drum drive and imparts arcuate reciprocating movement to the beam about the axis such that the printing station tracks movement of an object at the printing station. The screen is disposed substantially parallel to the axis and mounted for tangential movement to the drum and the object at the printing station. A screen drive imparts rectilinear reciprocating movement to the screen relative to the beam in synchronism with beam movement.
