ABSTRACT:
An apparatus for forming composite members has a frame assembly which is lowered onto a table. A sheet of vacuum bagging material, supported by the frame, covers a tooling surface on the table. Attached to the sheet is a downwardly depending seal which continuously extends around the sheet's periphery. This seal inserts into an upwardly opening channel that surrounds the perimeter of the table's tooling surface as the frame is lowered. The seal is inflated while in the channel and this provides in airtight seal between the sheet and tooling surface.
