ABSTRACT:
FIELD OF THE INVENTION
The invention relates to sewing machine bobbin winders having fill sensors. More particularly the invention relates to posts for avoiding a bobbin winder sensor on a sewing machine.
SUMMARY OF THE INVENTION
This invention eliminates the need for tedious hand winding of thread or yarn onto a spool. When used in conjunction with the bobbin winder of a typical sewing machine, the invention winds thread from a cone, skein, ball, or hank directly onto a spool. This is accomplished by installing the invention onto the bobbin winder found on most sewing machines. A separate spool may be mounted onto the invention, or the invention and spool may be constructed as a one piece unit. The invention positions the spool away from the bobbin winder's disengagement device, allowing for continuous winding of thread onto the spool with the bobbin winder. Use of the invention in this manner greatly reduces the amount of time and effort required to wind a spool, since hand winding is no longer required. The newly wound spool may then be used normally on any sewing machine, knitting machine, or serger.
