A packaging line for packaging sliced foodstuffs such as meat, meat products and cheese which are cut from logs of product by a slicing machine (1) comprises a first conveyor (11) to convey slices sliced by a slicing machine towards a packaging machine, sensor means (17, 18) arranged transversely equidistant from the centre line of the first conveyor (11) to detect the edges of the slices on the first conveyor and output a signal representative of the transverse location of the slices on the first conveyor, and a multi-element strip conveyor (14) downstream of the first conveyor (11) and arranged to receive the slices from the first conveyor. The second conveyor includes a transversely movable roller (16) at its upstream or downstream end, and means responsive to the output of the sensor means (17, 18) to move the transversely movable roller of the second conveyor a distance to centralise the slices on the packaging line. The sensor means (17, 18) or another sensor means (21, 22) is arranged to detect any angular displacement of slices on the packaging line. Means responsive to the output of the sensor means (17, 18, 21, 22) drives the different elements of the multi-element conveyor (14) or another multi-element conveyor (23) at different speeds to correct any angular misalignment of the slices. |
