A system ( 20 ) and method for hemming a vehicle body closure ( 32 ) includes a corner joining station ( 24 ) where formed sheet metal outer and inner members ( 36, 38 ) are initially joined to each other at their corners, a hemming station ( 26 ) where roll prehemming and roll final hemming of the peripheries of the outer and inner members is performed by roll robot hemming apparatus ( 68 ), and a delivery station ( 28 ) to which the hemmed closure ( 32 ) is delivered. At the hemming station ( 26 ), a plurality of fixtures ( 82 ) of different constructions selectively receive the particular closure member being processed during each cycle so as to have manufacturing flexibility. The fixtures ( 82 ) are located between a floor mounted conveyor ( 74 ) of robot transfer apparatus ( 30 ) and a floor mounted conveyor ( 84 ) of roll hemming robot apparatus ( 68 ) so that there is no interference between the transfer and hemming manipulations.
