Seam quality is improved by introducing the separately driven right and left active tension mechanisms. A large hook of 1.8-fold capacity (as compared with the standard size hook) is adopted. As a result, the frequency of thread changing is reduced in half. This is the world’s first sewing machine not only for jeans and heavy-weight materials but also for a foundation that is provided with a large hook. This sewing machine provides further stable seam quality. The corner stitching capability is provided only on the LH-4588C-7. The changeover from the normal stitching to the corner stitching is carried out semi-automatically using the lever while ensuring ease of operation.
