发明名称 Thread feeder for sewing machines
摘要 The thread feeder is composed of an upper (warp) thread dispenser consisting of a reel (1) and of a bottom (weft) thread dispenser consisting of a bobbin (2). Both dispensers are filled with the same quantity of thread with the same properties and are combined by removable assembly of the bobbin on a support (3) integral with the reel (1). This thread feeder is principally intended to avoid the operation of winding the bobbins by the user and to avoid the risks of errors during the choice of the compatibility of the thread of one bobbin with that of the chosen reel. <IMAGE>
