A draw-off device for taking down flexible goods with a steplessly adjustable draw-off tension from a machine producing or processing the goods, the draw-off device has at least one draw-off roller, a drive source, and a V-belt transmission connecting the draw-off roller and the drive source for driving the draw-off roller, the transmission comprising a V-belt pulley having two conical flanges, at least one of the flanges being mounted so as to be axially movable so as to alter an effective diameter of the V-belt pulley, the at least one movable flange being biased by spring force in direction of the other of the flanges, a V-shaped belt at least partially wrapping the V-belt pulley, at least one tensioning roller for and at least partially wrapped by the V-belt, a unit for adjusting the tensioning roller in a preselected position in order to adjust the take-down tension to a preselected value by a respective displacement of the at least one movable flange, and a locking unit for holding the tensioning roller in the preselected position.
