Beschreibung
Zusammenfassung:	The invention relates to a method for mounting vanes (10) in the periphery of a turbine engine disc (12), the disc (12) comprising cavities extending alternately with teeth, the vanes (10) respectively comprising: roots to be inserted into the cavities, shrouds (26), and blades (24) connecting the roots to the shrouds. According to the invention, the method comprises the following steps: (a) positioning the vanes (10) such that the root of each blade is axially facing one of the cavities of the disc; (b) providing a mounting tool (50) comprising a tip (40) with a shape partially matching the shroud (26) of one of the vanes; (c) engaging the tip (40) of the mounting tool (50) with the shroud (26) of the vane; (d) pivoting the shroud (26) of the vane by rotating (54) the mounting tool (50); and (e) axially inserting the root of the vane into the cavity of the disc.
