The Label Assembly line comprises of three lines: two work lines, and one "Not OK" line. The rims originating from the main system come to a stop in front of the operator, where a label is manually applied using a special label gun. The camera system then inspects the applied label, and if deemed satisfactory ("Ok"), the system proceeds. However, if a "Not Ok" is received during the label inspection, the product is sorted onto the rework line in the center for further processing. Transitions within the system are facilitated through a specialized timing system and a pneumatic transition system.
