Abstract: A machine for arranging groups of articles, such as cans of food, comprising an endless belt on which the articles to be combined, e.g. by a heat-shrink film, are disposed in rows, the machine being characterised in that it comprises a series of drive rollers adapted each to be applied against an article in a row in order to rotate it, detectors each disposed near an article of the row to be triggered by a reference on the article, each detector being connected to the corresponding drive roller for angular positioning of the references of all the articles to be arranged in groups and oriented in the row.
