Title
(EN) A METHOD FOR CUTTING MOVING MANUFACTURED ARTICLES
(FR) PROCÉDÉ DE COUPE D'ARTICLES MANUFACTURÉS EN MOUVEMENT
Abstract
(EN)
A method for cutting manufactured articles (M) comprises steps of advancing a manufactured article (M) along an advancement direction (A) at a predetermined speed; predisposing a cutting device (3) associated with the manufactured article (M) and movable along the advancement direction (A); advancing the cutting device (3); synchronizing the speed of advancement of the cutting device (3) with the speed of advancement of the manufactured article (M); activating the cutting device (3); retracting the cutting device (3); the steps of synchronising and activating the cutting device (3) are comprised between the advancement step and a corresponding retracting step in order to define a cutting cycle of the manufactured article (M). The cutting cycle comprises further steps of re- synchronising the speed of advancement of the cutting device (3) with the speed of advancement of the manufactured article (M).
(FR)
La présente invention concerne un procédé de coupe d'articles manufacturés (M) faisant appel aux étapes : d'avance d'un article manufacturé (M) dans un sens d'avance (A) à une vitesse prédéterminée; de disposition préalable d'un dispositif de coupe (3) associé à l'article manufacturé (M) et mobile dans le sens d'avance (A); d'avance du dispositif de coupe (3); de synchronisation de la vitesse d'avance du dispositif de coupe (3) avec la vitesse d'avance de l'article manufacturé (M) de façon à positionner le dispositif de coupe (3) au niveau d'une première zone de coupe prédéterminée (Z1) de l'article manufacturé (M); d'activation du dispositif de coupe (3) de façon à couper une première partie (P1) de l'article manufacturé; de retrait du dispositif de coupe (3). Selon l'invention, les étapes de synchronisation et d'activation du dispositif de coupe (3) sont comprises entre l'étape d'avance et une étape de retrait correspondante afin de définir un cycle de coupe de l'article manufacturé (M).
