Processing method for inserting electronic devices that are suitable for communicating in radio frequency into respective rubber sleeves, each of which comprises two overlapping strips (6, 7) that enclose therebetween a corresponding electronic device that is suitable for communicating in radio frequency; the processing method comprises the steps of: advancing a first rubber belt preferably arranged horizontally along an insertion path by means of a conveyor, wherein the first rubber belt is intended to form a first strip of each sleeve; and placing the electronic devices that are suitable for communicating in radio frequency upon an upper surface of the first rubber belt by means of a first feed device; the processing method is characterized in that it comprises the further steps of: placing, by means of a second feed device, upon the upper surface of the first rubber belt and upon each electronic device that is suitable for communicating in radio frequency, that was previously placed upon a corresponding sheet of rubber, that completely covers the electronic device that is suitable for communicating in radio frequency, wherein each sheet of rubber is intended to form a second strip of each sleeve; and cutting out, by means of a cutting device arranged downstream of the second feed device along the direction of travel of the first rubber belt, at least the first rubber belt in performing a perimeter cut around each electronic device that is suitable for communicating in radio frequency in order to separate each sleeve containing a respective electronic device that is suitable for communicating in radio frequency from the rubber belt. advancing a first rubber belt preferably arranged horizontally along an insertion path by means of a conveyor, wherein the first rubber belt is intended to form a first strip of each sleeve; and placing the electronic devices that are suitable for communicating in radio frequency upon an upper surface of the first rubber belt by means of a first feed device; the processing method is characterized in that it comprises the further steps of: placing, by means of a second feed device, upon the upper surface of the first rubber belt and upon each electronic device that is suitable for communicating in radio frequency, that was previously placed upon a corresponding sheet of rubber, that completely covers the electronic device that is suitable for communicating in radio frequency, wherein each sheet of rubber is intended to form a second strip of each sleeve; and cutting out, by means of a cutting device arranged downstream of the second feed device along the direction of travel of the first rubber belt, at least the first rubber belt in performing a perimeter cut around each electronic device that is suitable for communicating in radio frequency in order to separate each sleeve containing a respective electronic device that is suitable for communicating in radio frequency from the rubber belt. placing, by means of a second feed device, upon the upper surface of the first rubber belt and upon each electronic device that is suitable for communicating in radio frequency, that was previously placed upon a corresponding sheet of rubber, that completely covers the electronic device that is suitable for communicating in radio frequency, wherein each sheet of rubber is intended to form a second strip of each sleeve; and cutting out, by means of a cutting device arranged downstream of the second feed device along the direction of travel of the first rubber belt, at least the first rubber belt in performing a perimeter cut around each electronic device that is suitable for communicating in radio frequency in order to separate each sleeve containing a respective electronic device that is suitable for communicating in radio frequency from the rubber belt.
