Semi-dry head, 2-needle Lockstitch Sewing System
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 (only for the G type)
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. Since the sewing correction can be respectively set the multilayered portion run-on portion and for the top of multilayered portion, stitch gathering at the multilayered portion can be improved.
Corner stitching capability has been improved (only for the LH-4588C)
Changeover from the normal stitching to the corner stitching is carried out semi-automatically using the lever while ensuring ease of operation. The operator only needs to input data on the needle gauge/stitching angle through the operation panel. Then, the operator can start the corner stitching only by operating the lever during sewing. Thereafter, the sewing machine automatically changes the sewing mode between the normal stitching and the corner stitching.
This means that even the inexperienced operator can produce consistent seam quality while improving productivity
