ABSTRACT:
An automatic thread winding apparatus for automatically winding thread on a plurality of double-flanged bobbins of a type for use in sewing machines. The apparatus includes a bobbin supply unit for supplying bobbins in an arbitrary manner and in a row onto a thread winding unit. The bobbins in a row are successively transferred, one at a time, to the thread winding unit by a shuttling mechanism. Thread winding takes place while each one of the empty bobbins are firmly held between a tailstock and a headstock. The bobbin after having been wound with a predetermined quantity of thread is subsequently doffed onto a temporary storage mechanism wherein cutting of a portion of the thread extending between the filled bobbin and the temporary storage mechanism takes place. All of these processes are timed and sequentially performed by various cam mechanisms.
