Abstract
An intermediate cylinder comprising a main body, and a plurality of suction boxes formed in the main body at positions different with respect to a rotation axis of the main body. The intermediate cylinder further comprises a plurality of suction bores formed in the suction boxes so that they are open at an outer peripheral surface of the main body, an air suction source for generating suction force within the suction boxes, and a switching means for selectively switching connections between the plurality of suction boxes and the air suction source.
Claims11
A sheet-fed press including an intermediate cylinder to convey a sheet, said intermediate cylinder comprising:
- a main body;
- a plurality of suction boxes formed in said main body at positions different with respect to a rotation axis of said main body;
- a plurality of suction bores formed in said suction boxes so that they are open at an outer peripheral surface of said main body;
- suction force generation means for generating suction force within said suction boxes;
- switching means for selectively switching connections between said plurality of suction boxes and said suction force generation means;
- and
- air jet means for jetting air toward an outer peripheral surface of said intermediate cylinder so that said sheet delivered to said intermediate cylinder is stretched along said outer peripheral surface.
