ABSTRACT:
The needle bar (1) engaged in a pivoting cradle (2) is integral with a journal (3) connected by a connecting member (8) to a link (4) driven from the drive shaft (12) of the machine. In order to permit the head (23) of a loop holding member (25), mounted in the pedestal of the sewing machine, to engage in a loop (29) of the needle thread (27) during the ascending course of the needle (22), whatever may be its decentration, the connecting member (8) is formed by a bent extension of the crank pin of the link (4) engaged in a bore (7) of the journal (3).
