Abstract

In un procedimento per la fabbricazione di cinghie dentate di lunghezza qualsivoglia, un manicotto tubolare, comprendente uno strato di cordicelle (1) ed almeno uno strato in materiale elastomerico (2), viene preformato in autoclave senza vulcanizzare per produrre, sulla superficie interna del manicotto, una pluralità di cave (5) distanziate secondo un prestabilito passo di dentatura (P). Il manicotto viene tagliato elicoidalmente per ricavare una striscia continua (7) che viene successivamente avvolta su due tamburi di avvolgimento (8, 9) opportunamente distanziati, in base allo sviluppo circonferenziale che si vuole conferire alla cinghia.L'elemento anulare (10) ottenuto, ad avvolgimento ultimato, è centrato tramite le cave tra una matrice di stampaggìo (11) e un controstampo (12) e viene sottoposto ad una fase di pressatura e contemporanea reticolazione del materiale elastomerico (2), mediante chiusura secondo passi successivi fra una matrice di stampaggio (11) ed un controstampo (12) reciprocamente accostabili. Si determina così la formazione completa dei denti (3) all'interno della cinghie in lavorazione nonché la stabile unione delle spire contigue (10a) formate dall'avvolgimento della striscia continua (7)
