ABSTRACT:
A thread changing mechanism for sewing machines includes a magazine in which a plurality of needle holders is received, to be positively coupled to the sewing machine needle bar by a vertical motion of the magazine. Upon effecting a coupling, the magazine is retracted into a starting position remote from the needle bar, so that the needle bar with the needle holder can unobstructedly move during the sewing operation. The thread changing mechanism is mounted on a sewing machine as an attachment later, without particular adjustments. When the needle holders are held in the magazine the thread is engaged with each needle and held out of the way of the operating needle thread.
