AN APPARATUS FOR, AND A METHOD OF, PRINTING A PATTERN ON A CONTAINER COMPONENT A printing apparatus for printing a pattern on an endless side wall of a container component comprises six handling mechanisms 13 mounted on an indexing table 11, four printing heads 10 located at spaced apart positions on the indexing table 11, and a carrier 12 associated with each handling mechanism and arranged to carry a container 1 on which a pattern is to be printed. Each handling mechanism 13 comprises an outer roller 26 driven by a motor 20 and an inner roller 32. Each carrier 12 has an endless wall part 35 having a profile which matches that of the side wall of the container and a support part 38,39 for holding a container 1 on which a pattern is to be printed. The endless wall part is held in the nip between rollers 26,32. A sensor 41 and an encoder 45 are provided for detecting the position of carrier 12. During operation, the endless wall part 35 is driven between rollers 26,32, thus causing the side wall of the container to pass in front of a printing head 10 with a constant clearance therebetween. The printing head 10 is operated so as to print a pattern in a desired position. An alternative arrangement is described for the handling mechanism 13 and the carrier 12.
