1. A conveyor belt system comprising:
- a first conveyor belt;
a second conveyor belt adjacently aligned next to the first conveyor belt;
a planar conveying surface of the first conveyor belt forming an angle of less than 180 degrees with a planar conveying surface of the second conveyor belt;
a third conveyor belt adjacently aligned downstream of the first conveyor belt;
a fourth conveyor belt adjacently aligned downstream of the second conveyor belt and next to the third conveyor belt; and
a control unit configured to control the belt speed of each conveyor belt, such that an object entering the system at the first conveyor belt and second conveyor belt may be rotated at a certain degree with regard to the travel direction of each conveyor belt before exiting the system at the third conveyor belt and the fourth conveyor belt.

- 15. Method for turning packages in a conveyor assembly, said assembly comprising a first pair of conveyor belts being adjacent and having parallel conveying directions, the first pair of conveyor belts including a first pair of planar conveying surfaces forming an angle of less than 180 degrees, and a second pair of conveyor belts, being similarly adjacent and having parallel conveying directions, and where the second pair of conveyor belts are positioned downstream in alignment with the first pair of conveyor belts, wherein the belt speeds with each pair differs slightly such that a package entering the conveyor assembly is partly rotated in the first pair of conveyors and partly rotated in the second pair of conveyors, such that complete rotating is accomplished after the second pair of conveyors.

18. A conveyor belt system for conveying at least one object along a conveying direction from an upstream location to a downstream location comprising:
-
a first conveyor belt rotatable around a first pair of rollers; a second conveyor belt rotatable around a second pair of rollers, the second conveyor belt extending alongside the first conveyor belt along the conveying direction; a third conveyor belt rotatable around a third pair of rollers, the third conveyor belt being positioned downstream of the first conveyor belt; a fourth conveyor belt rotatable around a fourth pair of rollers, the fourth conveyor belt being positioned downstream of the second conveyor belt and extending alongside the third conveyor belt along the conveying direction; and a control unit configured to;
(i) rotate the first conveyor belt at a different speed than the second conveyor belt to rotate the object as the object is conveyed along the conveying direction by the first conveyor belt and the second conveyor belt; and
(ii) rotate the third conveyor belt at a different speed than the fourth conveyor belt to rotate the object as the object is conveyed along the conveying direction by the third conveyor belt and the fourth conveyor belt. - View Dependent Claims (19)
