The arm (1) possesses two end plates (2, 3) with central journal (4, 5), one (5) driven. Under the swivelling axis (A) and between the plates there is the lower product support (6) connected rigidly to the plates, while above the axis and between the plates there is the cap (7) mounted on the plates so that it can swivel about the hinge axis (K) on the journals (8, 9). The cap forms a stop (10) for the bottles or cans, with its longitudinal edges (11, 12) bent downwards and, between them, there is a strip (13), fastened to the end plates, making the stop unit (11, 12, 13) complete. This unit limits the swivel (F) of the cap but allowing it to move with the arm.
