ABSTRACT:
A conveyor has a pair of outer and a pair of inner endless conveyor elements having parallel conveying stretches extending in a transport direction, and respective rows of holders on the conveyor elements with the holders of the outer elements offset in the direction from the holders of the inner elements and the holder element of each inner and outer element aligned transversely with the respective holder of the other inner and outer element. A main shaft journaled at one end of the stretches defines a main axis and respective pairs of inner and outer sprockets on the main shaft guide the respective conveyor elements around the main shaft. One of the inner sprockets and one of the outer sprockets are axially fixed on the main shaft and the other inner sprocket and the other outer sprocket are displaceable axially along the main shaft. Only one of the pairs of sprockets is rotationally coupled to the main shaft. A secondary shaft is spaced from and parallel to the main shaft. A clutch is closable for coupling the secondary shaft to the main shaft for joint synchronous rotation and openable for relative rotation of the main and secondary shafts. Respective wheels on the main shaft are coupled to the sprockets of the other pair for joint rotation therewith and are both rotationally coupled to the secondary shaft. Respective wheels on the secondary shaft are aligned with and coupled to the respective main-shaft wheels.
