Abstract
A conveyor system in a packaging machine having leading and trailing drivers, which are disposed on endless parallel conveyor chains. To adjust the drivers to various sized boxes, the conveyor chains are adjustable transversely to the conveyor direction and are adjustable in phase. The chain wheels guiding the outer conveyor chains having the trailing drivers are disposed in a manner fixed against relative rotation, and one chain wheel is additionally axially displaceably disposed on the drive shaft. The middle chain wheel, which guides the conveyor chain having the leading drivers, is mounted on a hollow shaft disposed in a rotatable and axially displaceable manner on the drive shaft; this hollow shaft penetrates the hub of one outer chain wheel and has an aperture for an adjusting spring that connects the hub to the drive shaft. With a clamping ring that is secured in a sleeve engaging the hollow shaft, the middle chain wheel is joined to the drive shaft in an angularly adjustable manner and rotatable therewith.
