CURL REMOVAL APPARATUS AND ONE-SIDED/TWO-SIDED SHEET-FED PRESS

摘要

Disclosed is a curl removal apparatus (40) provided on a paper ejector (3) of a one-sided/two-sided sheet-fed press so that curls that occur during one-sided printing can be removed without the curl removal apparatus (40) touching the printing part of the print side during two-sided printing. The curl removal apparatus (40) comprises: curl correction members (41, 41) that form a recess (42) and extend in the widthwise direction of a printing sheet and arranged so as to face the transport track (32c) of the printing sheet; a suction apparatus (48A) that suctions the printing sheet, which runs along the transport track (32c), into the recess (42); and a movable support mechanism (43) that movably supports the curl correction members (41, 41) in a direction away from and towards the transport track (32c) of the printing sheet.
