发明名称 Spool winder for sewing machines
摘要 The invention is a removable attachment to the bobbin winder of a conventional sewing machine. It installs on a bobbin winder in lieu of a bobbin at one end and connects to a conventional spool at the opposite end. It provides for continuous winding of thread or yarn onto the spool by preventing disengagement of the bobbin winder. The invention consists of a flanged post which installs onto the bobbin winder's spindle. The post is long and narrow enough to avoid the bobbin winder's disengagement mechanism. This function eliminates the need for hand winding of spools. Once full, said spool may be used normally with any conventional sewing machine, serger, or knitting machine.
