In a suction roller for the movement of sheet-shaped workpieces, particularly for their acceleration or braking, economical production and a design advantageous for flow technology are achieved by providing a wheel body having channels starting at one face, which are open on at least one side and which rotate in sequence past a fixed suction nozzle positioned on one face, as well as a surrounding band (toothed belt) applied to the external circumference of the wheel body with protrusions (teeth) extending outward and indentations between them, with each indentation connected by means of at least one connection boring with a channel.
