Abstract

Un pneumatico vulcanizzato (2) viene montato su un cerchio (7) supportato in modo girevole da un'incastellatura primaria (5) oscillabile attorno a due assi (Z, X) ortogonali fra loro e rispetto all'asse di rotazione (Y) del pneumatico (2). Un elaboratore elettronico, in cui è memorizzata una sequenza di dati di base relativa ad un disegno d'impronta da riprodurre sul pneumatico, viene alimentato con una sequenza di dati di rilevazione relativi allo sviluppo superficiale di detto pneumatico. I dati di base vengono elaborati in funzione della sequenza di dati di rilevazione per creare una sequenza di dati di applicazione in base ai quali l'elaboratore elettronico provvede a comandare un emettitore a raggio laser (10) che traccia il richiesto disegno d'impronta sulla superficie esterna del pneumatico, come somma di successive porzioni distinte, ciascuna tracciata, sul pneumatico fermo, mediante oscillazioni del raggio laser entro un cono di ampiezza prefissata.
