Abstract (en)
[origin: EP2107433A1] The method involves providing an intermediate piece in soft material e.g. collet (12), piercing a hole in the intermediate piece, and mounting the intermediate piece on a support shaft, where the intermediate piece defines a face (18) and an edge (20) around the hole. A piece in hard material e.g. hairspring (10), is pierced by an opening. The piece in hard material is placed on the edge of the intermediate piece. The intermediate piece is deformed in a manner to integrate the pieces axially and angularly to form an assembly. The assembly is mounted on the shaft. An independent claim is also included for a collet-hairspring assembly comprising a flange that is folded over an intermediate piece.
