1. A method for optimising the cutting of elongated products, including metal bars or profiles for reinforced concrete, comprising the steps of:
a). arranging in succession along a feeding longitudinal direction a feeding zone, a cutting assembly and a measuring path for said products, said measuring path being configured to receive cut products by said cutting assembly on a respective receiving plane;
b). arranging laterally to said measuring path a storage divided into a plurality of compartments, for housing said cut products, grouped in bunches formed also after further cutting cycles, said bunches being defined as “closed” when said bunches include a required quantity of said cut products and “open”, in formation, until the required quantity of said cut products is reached;
c). arranging a manipulator assembly comprising at least one gripping device configured to grip said cut products and operating at least beside said measuring path, said gripping device being movable in a collecting motion according to a collecting direction, in an unloading motion according to an unloading direction and in a transfer motion relative to said measuring path;
d). in a suitable phase relationship feeding said products in any number along said measuring path and operating said cutting assembly in a cutting cycle, so as to make one or more consecutive cuts on said fed products and obtain along said receiving plane one or more series of cut products in succession, of the same size or of different sizes;
e). operating said gripping device in said collecting motion according to said collecting direction to at least partially collect said cut products in said cutting cycle, said collecting device holding said collected cut products gripped;
f). actuating said gripping device in said transfer motion, gripping said cut products collected by said gripping device;
g). positioning said gripping device at a selected compartment of said storage;
h). operating said gripping device according to said unloading motion in said unloading direction so as to release at least a part of said collected cut products into said selected compartment.
