An endless conveyor and belt where the conveyor belt is made from a plurality of laterally extending rods linked together at the edges of the belt to form a fixed pitch driving chain on one edge of the belt and a variable pitch chain on the other edge of the belt. The driving chain is formed of links extending upstream from rods and surrounding the adjacent upstream rods. The links in the variable pitch chain loosely surround the adjacent rod ends to permit relative movement between the adjacent rods. The rods rest on fixed supports which, during movement of the belt along the path of the conveyor, exert drag forces on the rods tending to rotate the upstream-extending links of the fixed pitch chain against seats on adjacent upstream links, thereby locking the links one to another and supporting the rods against drag forces without column loading. Drive forces are not transmitted across the belt. The ends of the rods at the variable pitch chain float with respect to each other.
