Printing apparatus for printing on a print substrate

摘要

The present invention relates to a printing apparatus for printing on a print substrate. The printing apparatus comprises: a printing station comprising a printing assembly for printing a first image on a first side of the print substrate during a first pass of the print substrate and printing a second image on a second side of the print substrate during a second pass of the print substrate; an input station for supplying the print substrate to the printing station; an output station for receiving the print substrate from the printing station, the output station comprising: a carrousel, the carrousel comprising at least two roll-up units, the carrousel being movable in a plurality of positions, in each of which a first roll-up unit of the at least two roll-up units is arranged in a substrate receiving position and a second roll-up unit of the at least two roll-up units is arranged in a position of the group of a substrate feeding position and a roll unloading position, wherein the roll-up unit in the substrate receiving position is adapted for receiving the print substrate, thereby forming a roll, and wherein the roll unloading position is different in location from the substrate receiving position.

1. A printing apparatus for printing on a print substrate, comprising:
a printing station comprising a printing assembly for printing a first image on a first side of the print substrate during a first pass of the print substrate and printing a second image on a second side of the print substrate during a second pass of the print substrate; an input station for supplying the print substrate to the printing station, the input station comprising at least one roll unit for supplying a print substrate; an output station for receiving the print substrate from the printing station, the output station comprising:
a carrousel, the carrousel comprising at least two roll-up units, the carrousel being movable in a plurality of positions, in each of which a first roll-up unit of the at least two roll-up units is arranged in a substrate receiving position and a second roll-up unit of the at least two roll-up units is arranged in a position of the group of a substrate feeding position and a roll unloading position, wherein the roll-up unit in the substrate receiving position is adapted for receiving the print substrate, thereby forming a roll, and wherein the roll unloading position is different in location from the substrate receiving position; the input station being arranged remote from the output station; the printing apparatus further comprising an input control mechanism adapted for selecting an input source for supplying the print substrate towards the printing station from one of the input station and the output station.
