1. A method for applying rubberized electronic tags to a tyre being processed, comprising:
arranging a continuous band and a plurality of rubberized electronic tags, wherein the continuous band is extended lengthwise along a longitudinal direction and has a front surface and a rear surface and wherein the rubberized electronic tags are adhered with a first adhesion force to the front surface of the continuous band and are arranged sequentially along the longitudinal direction of the continuous band,
peeling a rubberized electronic tag from the continuous band and,
applying, to a tyre being processed, said rubberized electronic tag peeled from the continuous band,
wherein the peeling said rubberized electronic tag from the continuous band comprises:
imposing, on said continuous band, a longitudinal sliding motion having a sliding speed with direction parallel to said longitudinal direction, and
imposing, on said sliding continuous band, a sliding path (P) comprising at least one first flat section, a recirculation section and a second flat section,
wherein the first flat section ends at a first transition line, wherein the recirculation section starts at the first transition line and ends at a second transition line parallel and adjacent to the first transition line to form a passage gap for the continuous band, and wherein the second flat section starts at the second transition line,
wherein, along the first flat section, the rear surface of the continuous band slides in abutment against a first flat abutment surface with sliding speed with direction parallel to said first flat abutment surface,
wherein, in a passage from the first flat section to the recirculation section, the rear surface of the continuous band is wound around a first edge delimiting the first flat abutment surface and defining the first transition line so that the direction of the sliding speed of the continuous band undergoes a first rotation,
wherein, in a passage from the recirculation section to the second flat section, the rear surface of the continuous band is wound around a second edge delimiting a second flat abutment surface defining the second transition line so that the direction of the sliding speed of the continuous band undergoes a second rotation, and
wherein, along the second flat section, the rear surface of the continuous band slides in abutment against the second flat abutment surface with sliding speed with direction parallel to said second flat abutment surface,
so that, following said first rotation at the first transition line, the rubberized electronic tags are gradually peeled from the continuous band, the continuous band continuing without rubberized electronic tags along the recirculation section, and continuing starting from the second transition line along the second flat section, adhering with a second adhesion force, smaller than the first adhesion force, to the front surface of the continuous band moving along the second flat section arriving from the recirculation section,
the method further comprising
overcoming, downstream of the second transition line, the second adhesion force, in order to definitively move the rubberized electronic tags away from the continuous band.
