The aim of the present invention is a method for making the machine sewing of articles in general. The common operations of sewing generally comprise a prearrangement of the superior spool (5) and passage of the thread through the thread guides to the needle and a successive prearrangement of the inferior bobbin (10) and insertion in the bobbin box (9). Once the machine is prearranged, the machine sewing of the article is made. According to the present method, the operation of prearrangement of the inferior bobbin comprises the winding of a leather thread (16) around it, while the operation of sewing of the article is made on the reverse side in such a way so that the leather thread is at sight. It is also provided a new sewing machine that allows the realization of the method in which the bobbin box comprises lift mechanisms for lifting the latch (20), thus allowing the passage under it of the continuous leather thread. |
