Abstract: A machine for cutting a moving object comprises a conveyor belt for carrying the object along an advancement direction at a line speed and comprises a driving and cutting unit configured to move in a cutting cycle according to a forward phase in order to perform the cutting of the moving object, and configured to move according to a return phase in order to return into the initial position of the cutting cycle. The cutting machine further comprises a processing unit configured to generate a driving signal for controlling the movement of the driving and cutting unit with an acceleration trend wherein the maximum absolute value of the acceleration within the return phase is smaller than the maximum absolute value of the acceleration within the forward phase.

Abstract: A device for adjusting cutting depth for the removal of weld beads inside profile sections such as tubes and the like, comprising a supporting frame (1) of an elongated shape and transverse dimensions suitable for enabling it to be contained inside a profile section or tube (2), the supporting frame (1) being associated, at one end thereof, with an arm or external rod, the device being characterized in that it comprises: —a plurality of rolling elements (3) associated with the supporting frame (1) at a pre-established mutual distance in a longitudinal direction and that partially project out from the body of the same supporting frame and are capable of coming into contact with the inner surface of the profile section or tube (2) in a zone that is diametrically opposite the one whereon the internal weld bead (4) lies; —at least two rollers (5), which are idle, arranged longitudinally at a pre-established distance from each other, and mounted on small frames (6) that are movable in transverse directions with re

Abstract: A cutting-off machine, comprising a cutting unit (2) being enabled to receive a tube (100) and to cut the tube (100) according to a plane transversal to a longitudinal axis (X) of the tube (100), movement means (8) enabled to grip stably a length (S) of cut tube (100) and move said length (S) away from the cutting unit (2) along a direction of advance (A) of the tube (100), and a cutting-off device (5) interposed between said cutting unit (2) and said movement means (8) and configured to realise cutting off of an inner welding seam (200) floating inside said tube (100).

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).
