ABSTRACT:
Method for pneumatically braking sheets in a delivery of a sheet-fed rotary printing press by means of blast air directed opposite to a sheet-transport direction for forming an air flow for braking the sheet includes adjusting the air flow for braking the sheet to a state of equilibrium between energy of the air flow acting upon the sheet and kinetic energy of the sheet, the sheet being carried in the region of a braking path in a contact-free manner by the air flow, and device for performing the method.
