Zusammenfassung:	PCT No. PCT/GB96/02915 Sec. 371 Date May 11, 1998 Sec. 102(e) Date May 11, 1998 PCT Filed Nov. 27, 1996 PCT Pub. No. WO97/21505 PCT Pub. Date Jun. 19, 1997A method of orienting cans on a continuously rotating machine, in which the machine has a plurality of rotating heads for can bodies (2), each of the heads having a sensor (9) for detecting the orientation of the can body. Each head comprises a mandrel (6), chuck (8) and can carrier (7). In one embodiment, the chuck and mandrel rotate at different speeds. The can body is generally held by the chuck but is transferred to the mandrel in order to impose the required orientation on the can body. In an alternative embodiment, each chuck is driven by an independent motor (15) and orientation is achieved by imposing a motion profile on the chuck to correct any error. An unique mark or series of marks is provided at or around a free edge of the can body so that the sensor can detect the orientation of the can body. Typically these marks are hidden in the finished product by a double seam which joins the can end to the can body.
