ABSTRACT:
A turning device for articles conveyed on a conveyor comprises a set of conveyor belts which together convey the article, the belts being driven at different speeds which increase from one side of the conveyor to the other. The speed differential is imparted by a drive shaft around which the belts pass, each belt passing around a pulley on the shaft. The diameters of the pulleys increase from one end of the shaft to the other and the pulleys are driven in rotation together.
