A tortilla making machine conveyor includes an endless belt adapted to be moved about an endless path by a rotatable drive roller. The belt is composed of elongated narrow boards and pivotal hinges. The boards are planar in cross-section, disposed in side-by-side relation to one another and extend in transverse relation to the path along which the belt is capable of being moved. The pivotal hinges extend in bridging relation across, and are attached to respective adjacent pairs of, the boards on interior sides thereof. Each hinge along adjacent edge portions of the pairs of boards has pivotally connected portions which project inwardly from the interior surface of the belt. The drive roller receives the endless belt in an entrained relation about it and has a series of drive teeth or cogs defined in spaced relation about its exterior periphery. Each of the drive cogs is adapted to successively receive in driving relation the inwardly-projecting pivotally-connected portions of one of the hinges as the drive roller is rotated to drivingly move the belt about its endless path.
