The transfer head is mounted on the arm for pivoting about the arm by way of an actuator which includes drive pulleys coupled by drive belts. The transfer head includes vacuum heads, one of which has associated with a suction cup thereof bellows for retracting the suction cup after the suction cup has sealed with the label to initiate peeling of the label from the stack. The suction cup is guidingly mounted so as to maintain its orientation at all times.
