Abstract
An overlay for a passenger conveyor roller track extends over the joints between segments to provide the engagement surface for the roller track. The overlay separates the engagement surface from the joints between adjacent segments to minimize vibration and improve the comfort of the ride. In one embodiment, an escalator includes a roller track having a support structure formed from multiple segments joined end to end and an overlay extending over the multiple segments. The overlay defines the engagement surface for the rollers engaged with the roller track.
