ABSTRACT:
An upper thread-hooking method for industrial sewing machines uses an upper thread-hooking device installed above one side of the needle and the presser foot for hooking the thread and cutting with a cutter by means of an electronic component moving a main sway arm and an auxiliary sway arm. The hooking device is located between the needle eye and the needle point behind the needle, performing a hooking thread process so that the hooking member never occupies the gap between the needle point and the presser foot. Then the sewing machine may have the highest rising level for the presser foot for comparative thick cloth to be sewn, without possibility of the hooking member colliding with the needle or the presser foot.
