Abstract
An escalator with steps having a tread surface and riser surface has riser brushes arranged at the riser surface. The riser brushes provide a barrier for the gap which is normally present between the tread surface of a first step and the riser surface of an adjacent step. The riser brushes may be mounted to a brush strip which is guided along the riser as the steps transfer between vertical and horizontal travel.
