Abstract:
1. A travelator conveyor for transporting passengers in a transport direction, the conveyor comprising: a first belt drum disposed at an end of the conveyor and defining a first rotational axis; a second belt drum disposed at a distance from the first belt drum in the transport direction and defining a second rotational axis; and a third belt drum disposed at a distance from the second belt drum in the transport direction and defining a third rotational axis, wherein the first, second, and third rotational axes are parallel to one another and extend transversely to the transport direction of the conveyor, and wherein each of the first, second, and third belt drums include a plurality of belt pulleys arranged thereon; a plurality of mutually parallel endless belt loops passing over at least one of the first, second, and third belt drums and having upper portions extending between the belt drums to define a moving conveying surface of the conveyor, wherein the plurality of mutually parallel endless belt loops comprise a plurality of first belt loops passed over the first belt drum and the second belt drum and a plurality of second belt loops passed over the second belt drum and the third belt drum, the plurality of first belt loops and the plurality of second belt loops being interleaved with one another on the second belt drum; and a comb plate arranged at the end of the conveyor and having a plurality of spaced teeth extending substantially parallel to each other in the transport direction, wherein the first belt loops are arranged to pass between the teeth, and wherein an upper surface of the first belt drum is at a lower level than an upper surface of the second belt drum such that the upper portions of the first belt loops are at an inclined angle relative to the upper portions of the second belt loops and the teeth of the comb plate extend substantially close to the second belt loops passing over the second belt drum.
