The machine has a main flow path (2) bordered by a hub (3) and a housing (1), and a row of blades arranged in the flow path. The blades form a blade end with a gap (11), where the end and the path border are movable relative to each other in proximity of the end. A part of the gap is retracted radially from the border and formed within the path. The gap is not limited at the retraction areas by the main flow path border and. The gap is limited by an edge guiding device that passes through a main flow and is fixedly connected to the border, where the device includes a row of profiles. |
