Abstract (en)
[origin: EP0872628A2] Each individual guide blade (2,3) is hollow and together with a head and a foot piece (4,5) forms a unified welding construction of metal plate. The foot pieces of all guide blades are suspendable in static accommodations of the turbine housing. All head and foot pieces consist of preferably two spaced apart plates similar to boiler plates (8,9,10,11), which through the arrangement of ribs, form pieces, strips or similar (12-15) form head and foot pieces stable on all sides. Facing plates (9,10) of the stable pieces act as welding plates for the face ends of the hollow blades (3).
