ABSTRACT:
An escalator has steps has steps that have a step-tread surface with a step-tread edge. Step brushes are arranged on the step-tread edge perpendicularly or vertically. Step brushes may also be arranged on the edge of the step's step-riser edge. The brushes provide a barrier against the entry of objects into the gap between a moving step and the stationery skirt-panel of the escalator.
