Abstract

The peg (7) has a diametral slot (11) intended to receive the glue. The hairspring (6) penetrates into this diametral slot (11) through a radial hole (12) made in the peg (7). Its end bears against the lateral face (13) of the diametral slot (11), thus determining its longitudinal position. The glue fills the diametral slot (11) as well as the hole (12). The slot (11) is produced with the aid of a disc cutter, the radial hole (12) then being drilled until it emerges into the slot. <IMAGE>
