Heavy-duty sewing machine used for decorative stitching, creating beautiful stitch patterns.


Many decorative seams now use thick thread stitching; the patterns and stitches are beautiful, especially in the decorative sewing of sofa covers, seat covers, tablecloths, etc., which require the use of heavy-duty sewing machines.

Heavy-duty sewing machines produce excellent decorative stitching effects, which are neat and beautiful, and are used by many sofa manufacturers.

Decorative stitching using thick threads, including round and flat/hollow threads, uses the thread as a visible stitch. The thickness of the thread knot is equivalent to the sum of two top threads and two bottom threads. Generally, the thickness of genuine leather is 2.5MM or more. The parts of the sofa cover where the visible stitching is pressed usually consist of two or more layers. If the thickness of the thick thread is 1MM or 1.2MM, then the thickness of the thread knot is 2MM to 2.4MM. The thickness of the two layers of sofa leather is 5MM or more, and genuine leather itself has strong toughness, so it is easy to hide the knot in the middle of the leather, without causing floating lines (the bottom lines are visible from above) or protruding lines (the top lines, or even large thread loops, are visible from below).

Heavy-duty sewing machines are the primary equipment used for decorative stitching in modern high-end sofa manufacturing, and can also sew relatively thin leather products.
