  • a vane apparatus includes a vane support and a plurality of vanes attached to the vane support.
  • a vane is usually manually attached to a vane carrier.
  • a guide blade root is inserted into a blade groove present on a guide vane carrier until the guide vane has assumed its intended position relative to the guide vane carrier.
  • An intended position of the vane relative to the vane support is conventionally secured by means of a caulking element, which is deformed for this purpose. Subsequently, a coupling of the attached to a vane carrier vanes can be done via a shroud.
  • a caulking member may be driven into a blade groove after a nozzle root has been properly located in the blade groove.
  • a guide vane device can be produced more quickly and thus more cost-effectively if first a caulking element is arranged in a blade groove on a guide vane carrier and subsequently a guide vane root is driven into the blade groove.
  • the latter way of producing a Guide vane apparatus is preferred within the scope of the invention.
  • the vane For appropriate attachment of a vane to a vane carrier, the vane is conventionally driven little ergonomically with hammer blows over a caulking. This is associated with a high manual effort and rapid fatigue of a busy with the Leitschaufelbefest Trent staff, so that usually a recovery time of fifteen minutes per hour worked for the staff must be scheduled.
  • a recovery time of fifteen minutes per hour worked for the staff must be scheduled.
  • vanes typically, with one-year manufacturing of vane assemblies, up to 100,000 vanes are to be correspondingly attached to vanes, which is traditionally associated with significant labor and time.
  • the object of the invention is to provide a new way of attaching vanes to a vane carrier with which such attachment can be done ergonomically and with less effort.
  • driving a vane into a blade groove provided with a caulking element on a vane carrier does not require any manual hammering, so that this driving in of the vane can be done with much less effort and ergonomics.
