ABSTRACT:
In a conveyor system having a flexible material-supporting belt made up of a plurality of sections connected end to end, there is provided a single, generally channel-shaped track for establishing a selected course of travel for the belt and an arrangement for moving the belt along the track inclusive of a pulling chain and a plurality of roller carriages on rollers affixed to the pulling chain at selected spaced intervals along the chain, the chain and rollers being entirely enclosed inside the track with the track providing entirely inside track surfaces for the rollers. Each roller carriage fastens to the belt and there may be provided a minimum spacing between roller carriages preferably one roller carriage per belt section with a roller carriage attached to each vertical chain link section placing a roller carriage at each pair of abutting ends of each belt section. The track configuration and roller mountings include combinations of vertical, horizontal and inclined dispositions for different applications.
