Zusammenfassung:	To provide an assembly that selectively controls the vacuum along sheet edges in a marker transport of a printing system.SOLUTION: A valve assembly for controlling an airflow along sheet edges on a vacuum transport assembly includes: a platen including one or more holes arranged in rows in a cross process direction; and a belt displaceable with respect to the platen in a process direction. The valve assembly includes: a flexible plate, including a first end, a second end, a first top surface, and a first bottom surface; and a first actuator connected to the second end and operatively arranged to displace the flexible plate.SELECTED DRAWING: Figure 1 【課題】印刷システムのマーカー搬送部においてシート縁部に沿って真空を選択的に制御するアセンブリを提供する。【解決手段】交差プロセス方向に列をなして配設された１つ以上の孔を含むプラテンと、プラテンに対してプロセス方向に変位可能なベルトとを含む真空搬送アセンブリ上のシート縁部に沿って気流を制御するためのバルブアセンブリであって、当該バルブアセンブリは、可撓性プレートであって、第１の端部、第２の端部、第１の上面、及び第１の底面を含む可撓性プレートと、第２の端部に接続され、可撓性プレートを変位させるように動作可能に配設された第１のアクチュエータとを含む。【選択図】図１
