Abstract
L'invention concerne la fabrication de cornières cintrées. On profile un feuillard en cornière droite en équerre 8. Pour obtenir des éléments de manchons 8y à bride intérieure, on lamine une aile 8f entre deux cylindres 11, 12 convergents de 2 à 3 degrés vers la pliure de la cornière, ou bien pour obtenir des éléments de manchons 8z à bride extérieure on lamine une aile 8e entre deux cylindres 21, 22 convergents de 0,1 à 3 degrés en s'éloignant de la pliure. L'invention s'applique à la fabrication d'éléments de manchons à brides internes ou externes.
