ABSTRACT:
A travelator conveyor is arranged such that an upper surface of a comb plate is at substantially the same level as a conveying surface. The conveyor includes a plurality of belt drums arranged parallel to one another transversely to a transport direction of the conveyor and a plurality of mutually parallel endless belt loops passing over the plurality of belt drums to define a moving conveying surface. The conveyor comb plate has a plurality of parallel spaced teeth between which some of the plurality of belt loops are arranged to pass. An upper surface of a first belt drum arranged at the end of the conveyor is at a lower level than an upper surface of a second belt drum such that upper portions of the belt loops passing between the comb plate teeth extend at an inclined angle with respect to the conveying surface.
