Abstract: In order, e.g., to provide a line sorter in which acoustic noise resulting from the polygon effect is reduced, there is disclosed a sorter (102) for sorting items of various shapes, sizes and weights, such as postal parcels or airport baggage. The sorter includes a closed loop comprising a plurality of sorting carts (302) for moving along an upper track section, a lower track section and end track sections in a moving direction. The plurality of carts are coupled at couplings (312), which enable the carts to pivot relatively to each other in at least one plane when in operation. Each cart is able to pivot relatively to an adjacent cart at two or more pivot points (404, 414, 1002) where the two or more pivot points are positioned a pivot point distance greater than zero apart in the moving direction of the carts.
