Abstract (en)

A sewing machine (1) includes a sewing head (11) having an upper shaft (142), a needle bar (151) and two needles (153), a double needle distance adjusting mechanism (30) and a double needle distance driving mechanism (40). The upper shaft (142) brings the needle bar (151) to move upward and downward, causing two needles (153) connected thereto to move synchronously. The double needle distance adjusting mechanism (30) includes an adjustment stem (31) extended through the needle bar (151) and brought by the double needle distance driving mechanism (40) to rotate, and an adjustment unit (32) located between the adjustment stem (31) and the two needles (153). The adjustment stem (31) in rotating enables the adjustment unit (32) to sidewardly move at least one of the two needles (153), so that the two needles (153) are located closer to or farther away from each other. With these arrangements, the distance between the two needles (153) of the sewing machine is adjustable at any time in the course of sewing workpieces requiring different double needle distances.
