Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a printing unit and a sheet printing machine that achieve higher printing output without deteriorating printing quality.SOLUTION: In a printing unit 2 of a sheet printing machine, that comprises a printing cylinder 10, an upstream transfer cylinder 5, and a downstream transfer cylinder 5, the transfer cylinders 5 have a device for decelerating or accelerating a sheet. Particularly, the device has at least one gripper bridge capable of moving in a substantially radial direction, and thereby the gripper bridge, and consequently tangential velocity of a sheet, is adjustable. According to the printing unit 2, sheets are conveyed at a slight interval from each other at low speed during a printing process.SELECTED DRAWING: Figure 2 【課題】印刷品質を損ねることなくより高い印刷出力を達成する印刷ユニット及びシート印刷機械を提供する。【解決手段】印刷胴１０と、上流側の渡し胴５と、下流側の渡し胴５とを備えるシート印刷機械の印刷ユニット２に関し、渡し胴５は、シートを減速あるいは加速する装置を有する。特に装置は、略半径方向で移動可能な少なくとも１つのグリッパブリッジを有し、これにより、グリッパブリッジ、ひいてはシートの接線速度は、可変である。このような印刷ユニット２により、シートを印刷プロセス中に低速の速度で互いに僅かな間隔を置いて搬送する。【選択図】図２
