Semi-dry head, 2-needle Lockstitch Sewing System Inspire the Knowledge in Sewing Adjustment. Epoch-making Sewing Systems in history. Digital sewing system proposes the production process added with a computerized new value to all the people who engage in production. Active tension mechanism is adopted Seam quality is improved by introducing the separately-driven right and left active tension mechanisms. The needle thread tension is automatically corrected according the sewing speed. Consistently seam quality is, therefore, achieved regardless of changes in sewing speed. The needle thread tension is automatically corrected according to the remaining amount of bobbin thread. Seam quality is, therefore, stabilized even when the remaining amount of bobbin thread has reduced. In the case of using the automatic needle thread tension correction feature according to the remaining amount of bobbin thread, the bobbin-thread change notification signal is provided to warn the operator when the remaining amount of bobbin thread has reduced to the predetermined level. Active presser foot mechanism is adopted Thanks to the adoption of the active presser foot, the presser foot pressure can now be corrected according to the sewing speed. Multilayered portion detection device (S/G type: Standard equipment, F type: Option) The sewing machine is provided as standard with the multilayered portion detection device. This device contributes to the realization of stable pitch / well-tensed seam when sewing the multilayered portion.
