1. A system for transporting substrates (3) in a printing machine, along a transport path oriented according to a longitudinal axis from at least one entry store (30) supplying the printable substrates, to at least one exit store (31) receiving the substrates, characterized in that it comprises:
mobile gripping means (2) each comprising an opening/closing system (22) ensuring the release or gripping of substrate (3), said gripping means (2) comprising front and rear gripping means, gripping each, either a substrate, respectively front and rear, or a part located at the front and at the rear of the same substrate, along the transport path, guide means (1), for guiding the gripping means (2) along the transport path, at least one motorisation means ensuring displacement of the gripping means (2) along the guide means (1), with independent displacement between at least the front gripping means (2) and the rear gripping means (2), the substrate transport system (3) being adapted to grip each substrate so as to tense and/or move substrates (3) of variable sizes along the transport path, the guide means (1), the gripping means (2) and their associated opening/closing system (22) being controlled by computer facilities. |
