An apparatus for automatically applying ejection rubber elements on a die-cutter, comprising a manipulator equipped with a needle gripper and a programmable control unit, wherein the gripper in turn comprises: - a front surface, - 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at which the needles cantileverly extend from the front surface to penetrate into an ejection rubber element to be withdrawn, and a retracted position, at which the needles remain flush with the front surface to disengage the ejection rubber element released on a die-cutter, wherein 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, characterized in that the control unit is programmed for: d') inserting in a single ejection rubber element the needles in the extracted position, and lifting the manipulator in order to separate that ejection element from a rubber sheet; e') aligning the ejection rubber element with the front surface of the apparatus, by partially retracting the needles to the intermediate position up to bring a face of the ejection rubber element to lean against the front surface so as to allow an image of the ejection rubber element to be captured in that position, and f') releasing the ejection rubber element onto the die-cutter. wherein the gripper in turn comprises: - a front surface, - 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at which the needles cantileverly extend from the front surface to penetrate into an ejection rubber element to be withdrawn, and a retracted position, at which the needles remain flush with the front surface to disengage the ejection rubber element released on a die-cutter, - a front surface, - 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at which the needles cantileverly extend from the front surface to penetrate into an ejection rubber element to be withdrawn, and a retracted position, at which the needles remain flush with the front surface to disengage the ejection rubber element released on a die-cutter, wherein 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, characterized in that the control unit is programmed for: d') inserting in a single ejection rubber element the needles in the extracted position, and lifting the manipulator in order to separate that ejection element from a rubber sheet; e') aligning the ejection rubber element with the front surface of the apparatus, by partially retracting the needles to the intermediate position up to bring a face of the ejection rubber element to lean against the front surface so as to allow an image of the ejection rubber element to be captured in that position, and f') releasing the ejection rubber element onto the die-cutter. d') inserting in a single ejection rubber element the needles in the extracted position, and lifting the manipulator in order to separate that ejection element from a rubber sheet; e') aligning the ejection rubber element with the front surface of the apparatus, by partially retracting the needles to the intermediate position up to bring a face of the ejection rubber element to lean against the front surface so as to allow an image of the ejection rubber element to be captured in that position, and f') releasing the ejection rubber element onto the die-cutter.
