Abstract
Disclosed is a portable device for winding thread around a bobbin from a spool of thread. The device includes a height adjustable thread holder configured to receive the spool of thread, a thread guide bar pivotable between a stored position and an operative position, and an adjustable tension feed device for applying tension to the thread during winding. The device also includes a spindle slot configured to receive one of a plurality of rotatable spindles that are interchangeable within the spindle slot so that different corresponding spindles can be used with the device. Also, a speed control knob for adjusting a speed at which the spindle rotates and thus at which thread is wound around the bobbin from the spool of thread, a fill knob for adjusting the amount of thread to be wound on the bobbin, and an automatic shut off mechanism are disclosed.
