Needle mechanism is directly participating on creation of stitch. Needle stick, together with needle, creates rectilinear movement in the most of sewing machines. However, in case of sewing machines with invisible stitching, it is movement of six-part joint mechanism, where the main part-needle, makes movement around the bow track. Kinematic parameters of movement of needle position, speed and acceleration, have direct connection with output of sewing machine and quality of created stitch.
