Abstract

Procédé consistant à former une partie courbée selon un angle déterminé d'un couteau en bande (1), sortant par intermittence de l'orifice de sortie d'un moule (20), à l'aide d'un organe poussoir (22) pouvant se déplacer sur une largeur déterminée, et d'une surface de moulage (21) située au niveau de l'orifice de sortie du moule (20), pendant que l'avance du couteau en bande (1) est arrêtée. Ce procédé permet de conférer aisément une courbure désirée à l'article.
