Abstract

A method and an apparatus for holding down a sheet on a feed table of a sheet-processing machine include a lowerable smoothing bar which can be driven according to a speed profile in time with the sheet-processing machine, which results in a targeted deflection of the smoothing bar. The deflection is preserved for the purpose of smoothing the sheet from the middle to the side.
