A hemming apparatus is provided for use with a robot in performing a hemming operation. The hemming apparatus comprises a support housing which mounts to a machine and has a pressurizable interior chamber having forward and rearward portions. A slide member includes a piston which is disposed in the chamber, and a plunger extends outwardly from the piston. Means are provided for attaching the housing to a nose having a central passageway. A bearing shaft is disposed within the central passageway, and means are provided for connecting the bearing shaft to the plunger. A hem roller is attached at the end of the bearing shaft. The rearward and forward portions of the chamber are connectible to a source of fluid pressure such that adjusting the chamber pressures moves the piston, thereby causing the bearing shaft to drive the hem roller into engagement with a work piece.
