Abstract

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).

A method for cutting manufactured articles (M), comprising the steps of advancing a manufactured article (M) along an advancement direction (A) with a predetermined speed;

predisposing a cutting device (3) in a stroke start position, said cutting device (3) being associated with said manufactured article (M) and movable along said advancement direction (A);
advancing said cutting device (3) along said advancement direction (A);
synchronizing the speed of advancement of said cutting device (3) with the speed of advancement of said manufactured article (M) so as to position said cutting device (3) at a predetermined first cutting zone (Z1) of said manufactured article (M);
activating said cutting device (3) so as to cut a first portion (P1) of said manufactured article;
characterized in that it comprises, within the same forward step, the further step of slowing down said cutting device (3) so as to advance it with a speed that is lower, null or possibly in an opposed direction, with respect to the speed of advancement of the manufactured article (M), and comprises the further steps of resynchronization of the speed of advancement of said cutting device (3) with the speed of advancement of said manufactured article (M) so as to position said cutting device (3) at a predetermined second cutting zone (Z2) of said manufactured article (M);
activating said cutting device (3) so as to cut a second portion (P2) of said manufactured article (M) of shorter length with respect to P1.
