<p>A print head assembly for use with a screen printing machine of the carousel type having a multiple armed fixed frame and a multiple armed movable frame mounted for rotation relative thereto. The print head assembly (40) comprises: a mounting frame (45) operatively connected to an arm (13) of the carousel. A carriage (44) adapted to carry spraying heads thereon is operatively connected to the mounting frame (45) and arranged for reciprocating movement relative thereto along a path of travel. Drive means is provided for causing the reciprocating movement, the drive means comprising a piston/cylinder assembly (41) including a cylinder (43) having a longitudinal axis, and opposed ends with a piston rod (42) extending from one of those ends there being a region defined between the lateral axes at respective ends of the cylinder (43) these lateral axes extending at right angles to the longitudinal axis of the assembly. The carriage (44) is characterized in that it is operatively connected to the piston rod (42) and arranged so that at least along part of its reciprocating path of travel it is disposed with the region between the ends of the cylinder (43).</p> |
