Traveling along the printing table impelled by two gears , each one of them engaged in one rack conveniently fixed in the corresponding side of said table. With the repeats digitaly adjustable to the mean lengths given by the racks teeth pitch. Dinamicaly rigidized by the shaft that desmodromicaly engages the two impelling gears between them and with the two side racks. With modularized plane rigid structure allowing easily building of different sizes both in width and maximum repeat length and giving a precise alignment after a round rail gide when in static position. With positionning equidirectionnality for each printig repeat. With the longitudinal synchronisation of the rack's pitch when they are fixed to the table's structure. Improving the printing precision, its productivity, its functionnal reliability and its dimensionnal and programatic adjustability.
