Abstract

Un elemento anulare (2), sostanzialmente piano, di materiale elastomerico di un pneumatico di un veicolo stradale viene realizzato avanzando uno stampo (3) per l'elemento anulare (2) stesso lungo un percorso (10) estendentesi attraverso una stazione di carico (38), in cui una striscia (56) anulare grezza di materiale elastomerico viene alimentata sullo stampo (3), una stazione di stampaggio (37), in cui un contro-stampo (25) viene accoppiato a pressione allo stampo (3) per un tempo determinato, ed una stazione di scarico (39), in cui l'elemento anulare (2) stampato viene scaricato dallo stampo (3); la striscia (56) anulare grezza venendo realizzata portando lo stampo (3) in rotazione attorno ad un proprio asse (51), ed alimentando, allo stesso tempo, direttamente sullo stampo (3) stesso, un nastro (46) continuo di materiale elastomerico.
