Abstract

Ce procédé permet d'obtenir l'amollissement ou l'arrondissement de l'extrémité des fibres ou filaments par la chaleur. Ce résultat est obtenu en chauffant les fibres ou filaments jusqu'à leur point de ramollissement en mettant entre eux un intermède qui empêche leur collage pendant la cuisson. Ces fibres ou filaments aux extrémités amollies ou arrondies peuvent sertir en art dentaire ou pour le polissage et le sablage.
