ABSTRACT:
An embroidery machine includes a base and an arm connected to an upright column post on the base. A needle bar is movably connected to the arm and a needle frame is connected to a distal end of the needle bar. A needle unit is connected to the needle frame and removably extends through the holes in a needle plate on a top of the base. An alignment device is connected between the needle bar and the needle frame so that the needle frame can be connected to the needle bar by a guidance of the alignment device.
