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.
A corrugated board sheet transporting system in a printing line, in which a plurality of printers, each provided with a printing cylinder having a printing die mounted thereon and a press roll opposing to said printing cylinder, are aligned straight in a direction of forwarding a corrugated board sheet, said printing cylinder being designed to be ascendable;
A corrugated board sheet transporting system comprising a multiplicity of printers, each comprising a press roll which is provided below a transportation path of a corrugated board sheet and a print cylinder provided above said transporting path so as to be ascended and descended, said multiplicity of printers being disposed with a predetermined space in between in a direction of forwarding said corrugated board sheet, a first feed belt unit being provided on said print cylinder side of said transportation path and a second feed belt unit being provided on said press roll side of said transportation path, said first feed belt unit being comprised of a first conveyor belt which is positionally immovable in said sheet forwarding direction and a second conveyor belt which is positionally shiftable forwardly and backwardly in said sheet forwarding direction so that said corrugated board sheet is held and transported by said first and second conveyor belts and said second feed belt unit, and wherein
