Summary:Adjustment mechanism for properly gripping paper sheets of different lengths to be transferred for multicolor printing including adjusting means for adjusting the circumferential spacing of cylinder gripping means, particularly on rotary printing machines. On one end of a shaft of a sheet transfer cylinder there is rotatably mounted a gear wheel and on one end of a shaft of a cylinder for turning papers sheets is a first drive gear and a second drive gear which is adjustable relatively to the first drive gear. One drive gear of the turning cylinder is engageable with the drive gear of the sheet transfer cylinder, so that changing of the rotational orientation between the drive gears of the sheet turning cylinder effects a rotation of the gear wheel of the sheet transfer cylinder and a change in the circumferential spacing between the mechanical grippers and the suction gripping elements thereof.
