A method for releasing printed sheets on to a stack has a pneumatic braking system with air jets directed to both sides of the sheet at the time of release

摘要

The printing unit (1) has a number of color and process stations (1.1,1.2) as the sheets (2.2) are drawn off the input stack (2.3), processed and finally conveyed to the output stack (3.2) by grippers (3.6) which automatically release the sheet which is halted by air jets (4.3,4.4).
