sewing machines pass the needle only part-way through the fabric. On a machine needle, the eye is right behind the sharp point, rather than at the end. The needle is fastened to the needle bar, which is driven up and down by the motor via a series of gears and cams. When the point passes through the fabric, it pulls a small loop of thread from one side to the other. A mechanism underneath the fabric grabs this loop and wraps it around either another piece of thread or another loop in the same piece of thread.
