Abstract:
1. A cutting apparatus for perforating beams, each of said beams having two longitudinal edges delimiting a body portion, said cutting apparatus comprising: a main longitudinal support structure; a cutting zone located along the main longitudinal support structure; a controllable conveying assembly comprising at least one conveying belt located in the cutting zone, supporting and translating the beams one after the other longitudinally along a conveying direction, at a translation speed; a detector to detect a presence of a beam in the cutting zone and to generate a detecting signal accordingly; a pair of longitudinal bars provided with rotatable free wheels, the longitudinal bars being aligned with the longitudinal edges of the beams, the rotatable free wheels pressing the longitudinal edges of the beam against the at least one conveying belt; a controllable router, the router being located in the cutting zone, said router being controllably movable substantially orthogonally and transversally with respect to the beam; and a controller including a hard disk for storing a predetermined perforation pattern, the controller being operatively connected to the conveying assembly, the detector and the router, the controller having an input for receiving the detecting signal and outputs for sending control signals to: and thereby perforate the body portion of the beam following the predetermined perforation pattern.
