An apparatus for conveying one or more objects along a conveying path in a conveying direction includes an endless conveyor chain formed of modular links arranged in rows in a direction transverse to the conveying direction. The links include spaced outer side links forming a part of a conveying surface for the objects to be conveyed and intermediate links interconnected with side links by connector rods, the chain having at least a forward run for conveying one or more objects in the conveying direction. A driver is provided for driving the conveyor chain, and includes a first sprocket adapted for engaging at least one side link along at least one side of the chain, the first sprocket mounted for rotation about an axis generally orthogonal to the conveying direction and the transverse direction. The sprocket may comprise a split sprocket, and may be adapted for pivoting movement.
