MODERN ASSEMBLY LINES WITH HIGH AUTOMATION LEVELS RESULT IN HIGH CAPITAL EXPENDITURES AND, THEREFORE, NEED HIGH OUTPUT TO BE PROFITABLE. RECOMMENDED SOLUTIONS ARE FLEXIBLE AUTOMATION AND STRATEGIES THAT ACHIEVE HIGH TECHNICAL AVAILABILITY AND HIGH UTILIZATION OF THE EQUIPMENT. THEREFORE, FLEXIBILITY SHOULD ENABLE EASY AND QUICK ADAPTATION TO VARIOUS TASKS. ROBOT SYSTEMS, MOSTLY USED AS PROBLEM SOLVERS FOR FLEXIBLE ASSEMBLING, REQUIRE FLEXIBLE PART PRESENTATION TO SUCCEED. A SIMILAR FLEXIBILITY LEVEL IS RECOMMENDED, BUT OFTEN IS LACKING IN TODAY'S USED FEEDERS. FOR THIS REASON, EASY CHANGEABLE FLEXIBLE FEEDING SYSTEMS ARE NECESSARY TO REDUCE DOWNTIMES, EQUIPMENT COSTS, AND OPERATION EXPENSE. DURING VARIOUS PROJECTS AT THE INSTITUTE, STRATEGIES FOR FLEXIBILITY OF PART SUPPLYING HAVE BEEN DEVELOPED AND APPLIED. THIS PAPER DESCRIBES RESULTS OF THESE DEVELOPMENTS PRESENTING A SETUP INVESTIGA
