Abstract
A sewing machine having a cartridge containing a spool of thread and a pre-threaded needle mounted inside of the head, the cartridge having the lower end thereof terminating in proximity to the fabric to be worked upon. The cartridge is provided with integral means for receiving a spool carrying ribbon-like material, the cartridge having a channel means integral therewith adjacent the aperture of the cartridge through which the needle passes, the spool of ribbon being so mounted, and the channel so configured, that the natural unwinding tendency of the ribbon automatically positions the ribbon on the fabric in the path of the needle.
