In a device for reducing the frictional force between a guiding or carrying element for sheets in a sheet-processing machine, in particular rotary printing machines, guiding and carrying elements acted upon by throttled blowing air include a sheet surface, orifices fluidically connected to a hollow interior, and a throttle disposed in the hollow interior. The elements are to be connected to an air source for blowing air out through the orifices and for generating an air cushion between a sheet and the sheet surface. Each of the orifices is preceded by the throttle with respect to a direction of air from the air source.

In a device for reducing the frictional force between a guiding or carrying element for sheets in a sheet-processing machine, in particular rotary printing machines, guiding and carrying elements acted upon by throttled blowing air include a sheet surface, orifices fluidically connected to a hollow interior, and a throttle disposed in the hollow interior. The elements are to be connected to an air source for blowing air out through the orifices and for generating an air cushion between a sheet and the sheet surface. Each of the orifices is preceded by the throttle with respect to a direction of air from the air source. ducing a frictional force between sheets and an auxiliary stack table for sheets in a feeder of a sheet-processing machine, comprising: a rake bar defining a hollow interior; said rake bar having: a sheet surface; orifices fluidically connected to said hollow interior; and a throttle disposed in said hollow interior, said throttle being a plurality of perforated plates disposed one above the other, and swirl chambers being disposed between each of said perforated plates; said rake bar to be connected to an air source for blowing air out through said orifices and for generating an air cushion between a sheet and said sheet surface of said rake bar; and each of said orifices preceded by said throttle with respect to a direction of air from the air source. 11. A device for reducing a frictional force between sheets and an auxiliary stack table for sheets in a delivery of a sheet-processing machine, comprising: a rake bar defining a hollow interior; said rake bar having: a sheet surface; orifices fluidically connected to said hollow interior; and a throttle disposed in said hollow interior, said throttle being a plurality of perforated plates disposed one above the other, and swirl chambers being disposed between each of said perforated plates; said rake bar to be connected to an air source for blowing air out through said orifices and for generating an air cushion between a sheet and said sheet surface of said rake bar; and each of said orifices preceded by said throttle with respect to a direction of air from the air source. 12. A sheet-fed rotary printing machine, comprising: sheet guiding and carrying devices; a sheet transporting element for reducing a frictional force between sheets and said guiding and carrying devices; said sheet transporting element cooperating with said sheet guiding and carrying devices to convey sheets in a printing machine; said sheet transporting element defining a hollow interior; said sheet transporting element having: a sheet surface; orifices fluidically connected to said hollow interior; and a throttle disposed in said hollow interior, said throttle being a plurality of perforated plates disposed one above the other, and swirl chambers being disposed between each of said perforated plates; said sheet transporting element to be connected to an air source for blowing air out through said orifices and for generating an air cushion between a sheet and said sheet surface of said sheet transporting element; and each of said orifices preceded by said throttle with respect to a direction of air from the air source.
