Abstract

L'invention concerne une unité outil d'une machine de pétrissage rotatif pour façonner des pièces de préférence en barres ou tubulaires. Cette unité outil présente une pluralité d'outils de façonnage (22) qui sont agencés autour d'un axe de travail (18) et peuvent être animés d'un mouvement de levée radialement à l'axe de travail (18) au moyen d'un entraînement d'outil. Des moyens de réglage (38) associés aux outils de façonnage permettent de régler des positions de levée des outils de façonnage (22) de sorte que, à l'état fermé, lesdits outils de façonnage (22) soient en appui les uns contre les autres avec une pression de fermeture dépendant des positions de levée réglées. Selon l'invention, l'unité outil présente un dispositif de mesure pour mesurer un paramètre permettant de contrôler la pression de fermeture obtenue avec les positions de levée réglées des outils de façonnage (22).
