  • 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.

  • 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.
