Abstract
A device for the guidance of an endless belt for escalators or moving walkways in an endless belt of an escalator or a moving walkway, the chain rollers are guided by way of a support rail having a running track and by way of a compensating rail having a running track, and at the entry of a chain wheel, which deflects the endless belt, the chain rollers move from the rectilinear running track of the support rail onto the curved running track of the compensating rail and move from the compensating rail, at a tangent point, into engagement with the chain wheel, with the chain rollers being displaced, towards the chain wheel, by a spacing (h.sub.0), during the movement thereof, from the running track of the support rail to the tangent point, with the spacing being measured transversely to the running direction, in the direction extending at right angles to the running direction, with this displacement having an advantageous effect on the quietness of operation of the endless belt.
