[0004] In the present discussion, the term "sorting" signifies a sorted collection of products. Subsequently to said "sorting" operation, there follows a packaging operation: the packaging operation is preferably carried out directly after the sorting operation, i.e., the sorted collected products are subjected to packaging operations; the packaging is preferably carried out indirectly, i.e., the sorted collected products are subjected to one or more operations that move them to another location where the packaging is carried out.
[0005] The known systems are suitable for operating and handling large quantities of products at high speeds , in the order of hundreds of products per minute .
[0006] Said systems have specific operating stations suitable for carrying out specific operations .
