Abstract: Apparatus for applying printed matter onto objects (10) has a conveyor (11) on which objects (36) are carried under one or more printing heads (16). The conveyor (11) is formed by multiple rotatable conveyor bodies (12) and is driven by a drive roller (18). The printing head (16) is also connected to the drive roller (18) by way of a linkage (14) which permits driving of the printing heads in a reciprocating manner. An accelerator device (13) is also drivably connected to the drive roller (18) and acts to rotate the conveyor bodies (12) which form the conveyor. In use, objects (36) on the conveyor (11) are rotated by the rotation of the conveyor bodies (12) under the action of the accelerator device (13), the rate of this rotation being matched to the rate of reciprocation of the printing heads (16) whereby a stationary surface on the object (36) is presented for printing.
