Abstract
In this mechanism (7) a moving hook comprises a body (20) provided with a nose (202) for bearing against a corresponding knife (14), and a flexible blade (21) secured to the body so as to be capable of moving relative thereto and designed to interact with a retaining lever (16) belonging to the selector device. The selector lever (16) forms a ramp (313) over which a portion (214) of the resilient blade (21) slides when the hook (13) is moved in the vicinity of its top dead-center position. The ramp on which the selector lever slides is shaped in such a manner that the component (F.sub.A+F.sub.B+F.sub.C) parallel to the travel direction (X-X') of the moving hook (13) of the resultant of the forces (R.sub.A, R.sub.B, R.sub.C) acting on the flexible blade (21) when in contact with the ramp (313) in the vicinity of the top dead-center point of its travel and at the beginning of its downward movement (F.sub.14), is directed downwards.
