ABSTRACT:
A sewing machine is provided having an automatic bobbin loader. The automatic bobbin loader includes a hook assembly mounted beneath the sewing plane having a bobbin receiver. The hook assembly is driven by a drive shaft, and is moveable from a first, operating position, to a second, loading position. A bobbin loader is mounted adjacent to the hook assembly in the second position. The bobbin loader includes a suction tube that removes any remaining bobbin core. The bobbin loader then loads a replacement bobbin from the bobbin loading assembly into the bobbin receiver, prior to the hook assembly being returned to the operating position. Additionally, in order to sew through thick material, the needle is carried by a needle carriage which moves in time with the material being sewn to maintain the needle generally vertical throughout the time it is in the material being sewn.
