An apparatus and a method for automatically applying, without the intervention of an operator, rubber elements on a die-cutter during the manufacturing step thereof, are described. The apparatus comprises a manipulator, preferably a robotic arm, and a needle gripper. The gripper withdraws the water jet pre-cut rubber elements from a sheet with double-sided adhesive tape, and places them one by one at the point provided for by the working program. 117456. An apparatus () for automatically applying ejection rubber elements () on a die-cutter () , comprising a manipulator () equipped with a needle gripper () ,{'b': '6', 'claim-text': [{'b': '14', 'a front surface (),'}, {'b': 15', '14', '15', '14', '7', '15', '14', '7', '4, 'a plurality of needles () movable with respect to the front surface () between an extracted position, at which the needles () cantileverly extend from the front surface () to penetrate into an ejection rubber element () to be withdrawn, and a retracted position, at which the needles () remain flush with the front surface () to disengage the ejection rubber element () released on a die-cutter (),'}, {'b': 15', '7', '14', '14, 'characterized in that the needles () can be stopped at an intermediate position in-between the extracted position and the retracted position, to lay down the ejection rubber element () against the front surface (), without disengaging the ejection rubber element ().'}], 'wherein the gripper () in turn comprises211314273157. The apparatus () according to claim 1 , comprising a presser element () movable with respect to the front surface () to exert pressure on a sheet () of ejection rubber elements () that rests on a working plane () claim 1 , while the needles () are gripping a single ejection rubber element ().311314.
