A multi-axis rotary seal system to provide a gas-tight seal between a stationary hood and the end of a rotating tube kiln comprises a stationary hood positioned at the end of the rotary tube and having extended therefrom, a fully flexible bellows attached at the other end to a structural ring which, in turn, is attached to a graphite ring, slidably pressed against a flange on the rotary tube to form an atmospheric seal. The structural ring is held to the stationary hood by multi-axis supports that allow movement of the ring in three axial directions. In operation, during expansion and contraction of the rotating tube and eccentricities of motion, the integrity of the slidable seal formed by the graphite ring against the mating surface of the tube flange, is maintained by a biasing device pressing the graphite ring and the tube flange together in slidable engagement.

A punch press, of the type capable of producing a piece from a sheet of material, the piece being attached to the sheet by a tab, is provided with a separation assembly that fits into a standard tool station. The invention provides for parting of the piece from the sheet, and automatic transport of the parted piece to a position overlying a hinged drop door provided as part of a removal assembly. The invention eliminates the need for manual parting and removal of the piece from the punch press.
