Abstract
Il nastro oggetto del presente trovato prevede, in corrispondenza della sezione longitudinale compresa tra le fibre adiacenti dei moduli consecutivi, l'inserimento in linea di almeno un elemento di separazione filiforme, ad alta resistenza a trazione, inglobato nella resina della matrice, atto a facilitare la suddivisione manuale del nastro in moduli, in particolare di quattro fibre, senza l'impiego di alcuna attrezzatura specifica.
