Abstract

A sheeter apparatus includes: a cutter cylinder 12 for cutting a transported web W into sheets S in cooperation with a fixed knife 13; lower high-speed transportation belts 16 for transporting a cut sheet S; and a suction device 36 for sucking the cut sheet S from suction ports 41d of a suction roller 41, which causes the lower high-speed transportation belts 16 to travel, in such a manner that a surface of the sheet S which is on the other side of the surface facing the cutter cylinder 12 adheres to the outer peripheral surface of the suction roller 41.

Description

technical field [0001] The present invention relates to a sheet apparatus for cutting a printed web which has been dried and cooled after printing into sheets of predetermined length and for subsequent use while flattening the edges of the sheets Stack the resulting flakes. Background technique [0002] Web rotary presses are provided with a cutting unit for cutting the printed web, which has been dried and cooled after printing, into sheets of predetermined length and for subsequent stacking while flattening the edges of the sheets The flakes obtained. This cutting device is designed to cut the web conveyed between the cutting knife and the fixed knife of the rotating cutting drum (cutting drum) into sheets, and then discharge the sheets to the Inside the frame on the stacker. [0003] Since the cutter and the fixed knife of the cutting drum become dull, as the cutting drum rotates, the cutter rotates while the rear end of the sheet, which is the cutting position of the ...
