Abstract

In un pneumatico per veicoli, provvisto di una fascia battistrada (9) realizzata con mescola a basso contenuto di nero di carbonio vengono previsti uno o più inserti conduttivi (12) in elastomero ad alto tasso di nero di carbonio, inglobati nella fascia battistrada stessa ed estendentisi, secondo uno sviluppo anulare, lungo l'intero sviluppo circonferenziale di quest'ultima. Ciascun inserto conduttivo (12) attraversa l'intero spessore della fascia battistrada (9), affacciandosi esternamente sulla superficie di rotolamento (9a) della fascia battistrada stessa e, da parte opposta (12) agendo in contatto cintura (6), sulla tela di carcassa (2), o su un'altra parte del pneumatico avente sufficiente conducibilità elettrica affinché la carica elettrostatica accumulata dal veicolo durante la marcia possa essere scaricata a terra attraverso il pneumatico tramite gli inserti conduttivi stessi.
