A headbox in a former for wet-forming of a fibre web has vanes (14) which separate channels (15) in the slice chamber (8) of the headbox, which channels communicate with turbulence channels (6), each vane being mounted to an anchoring element (10) with an arrangement, which comprises a pivot member (16) on the vane and an engagement groove (11) in the anchoring element. In accordance with the invention, the mounting arrangement further has an assembly bar (23) with a protrusion (24) for being received in said engagement groove to form a rigid joint and a journalling groove (25), arranged at a distance from the anchoring element and with a side opening (26) opens towards the vane (14) and having opposite pivot surfaces (27). The pivot member (16) of the vane is arranged to be received in the journalling groove (25) to co-operate with its pivot surfaces (27) to form an axis of pivot (28). The invention also relates to such a mounting arrangement and a method for mounting a vane by means of such a mounting arrangement.
