Can ends having an off-center aperture, are each orientated by a resiliently mounted peg which engages a surface of the can end and is rotated about a pitch circle for one complete revolution. The peg seeks and enters the aperture and thereafter causes the can end to rotate with it until it stops at a position corresponding to the desired orientation of the can end. The peg is then withdrawn from the aperture and the can end, supported in a carrier plate and is delivered to a moulding machine (not shown) in which a plastics closure is moulded into the aperture.

Apparatus for orientating about their central axes, circular can ends of the kind having an off-centre aperture therein comprising: (a) means to deliver each can end to an orienting station; (b) resiliently mounted orientating means supported at the orentation station for rotation about a pitch circle intersecting the aperture; (c) means for effecting relative motion between the orientating means and a can end at the orientating station to bring the orientating means into engagement with the can end; and (d) means for rotating the orientating means about the pitch circle to cause the orientating means to seek and enter the aperture such that continued rotation of the orientating means brings the can end to a chosen orientation at which rotation is stopped.
