To provide sheet brake equipment of a sheet-fed printing press, which does not use a vacuum wheel in comparison with conventional equipment, and which enables printing on the whole surface except both lateral margins without concern about stains in the printing on the whole surface except both the lateral margins.

Printing paper (P) is sandwiched between a paper guiding roller (13) and a paper retaining roller (12) in such a manner that timing is provided during a period from the time when the printing paper (P) is released by a chain gripper (1) to the time when the printing paper (P) abuts on a paper abutting part (5), so that a sheet brake can be applied by both the two lateral margins.
