<p>The machine (2) has a marking or labeling element e.g. punch (6), for marking or labeling pieces, and a delivery unit for delivering the pieces to be marked or labeled opposite to the element. The delivery unit has arms (20, 22) rotating about a common geometrical axis (X2) and carrying supporting bodies e.g. mandrels (213, 233), to support the pieces. The delivery unit comprises independent driving units for driving one of the arms to rotate around the axis independent of the other arm. The driving units have a brushless electric motor (30) mounted on a plate (4E) of a chassis (4). An independent claim is also included for a method for marking and labeling pieces.</p> |
