ABSTRACT:
Disclosed is a corrugated board sheet transporting system in a printing line, in which a plurality of printers, each provided with an ascendable printing cylinder having a printing die mounted thereon and a press roll opposing to the printing cylinder, are aligned in a corrugated board sheet forwarding direction. This system consists of a first feed belt unit and a second feed belt unit for holding the corrugated board sheet with the first feed belt unit, which are disposed between every adjacent two printers; the first feed belt unit consisting of a first conveyor belt which is fixed with respect to the sheet forwarding direction and a second conveyor belt which can be shifted forward and backward with respect to the sheet forwarding direction; wherein the second conveyor belt is designed to be shifted, when the printing cylinder is ascended or descended to be spaced from the press roll, to advance to a position closer to the printing cylinder in the printer. Since the first conveyor belt and the second conveyor belt are disposed to overlap partly with each other, the corrugated board sheets can stably be transferred therebetween even in the absence of the printing cylinder.
