Abstract: An automatic system for phasing advancing articles having a planar supporting base and a method of phasing objects with this device. The method allows the collection in real time of data concerning the position of the articles (OG), transmit it to an aggregation center (MCR), storing it in a data structure and reprocessing it for determining variations of speed to be imparted to the articles, and sending commands to interfacing means (MAL) towards motors (4). The system comprises individually motorized transport modules (MCS) disposed on a frame (T) and defining a sliding plane for the objects, optical sensors (SO) disposed interstitially to MSC modules for detecting instantaneous data on the position of the objects, and automatic steering and control means (UGC) for changing the speed of the articles so as to create a predetermined gap therebetween, by receiving from sensors (SO) feed back data and changing the speed of modules MSC by acting on a main shaft (2).
