The basic production process of a set of couches can be divided into: the production of sofa frames, frame bottoming, sofa fillers, jacket cutting and sewing, and a set of sofa jackets. Production of sofa frame Before starting the production of sofas, experienced masters will draw a good sofa board, and without a good sample, it is impossible to make a good set of sofas. After the board is ready, the frame of the sofa can be officially made. At present, sofa frames are mainly divided into solid wood and composite boards. The frame of a sofa is similar to a human skeleton, supporting the entire sofa. The firmness of the sofa frame structure and the rationality of the design angle will affect the quality and functionality of the sofa. Underlay The foundation mainly involves adding springs and bandages to the sofa. 1. Rubbing: Tie rubber bands on the back of the sofa! Because the load-bearing capacity of the back frame is not as large as that of the seat frame, rubber bands can be used. Some people also use so-called black belts, which are made from discarded tires. 2. Safety spring: Springs generally use serpentine springs (also known as S-shaped springs) to increase the load-bearing capacity of sofas, and can be fixed with specialized spring clips to reduce noise. Spring installation must be firm and there must be no abnormal movement when pressed hard. The quantity depends on specific needs. 3. Mesh fabric: Cover the cushion area with breathable mesh that you know well, which can effectively prevent moisture and increase the lifespan of the sofa. Sofa filling The padding inside the sofa includes sponge, down, and artificial cotton. The types of sponges are mainly high, medium, and low density sponges. The sponges inside the sofa will affect the sitting sensation, and the quality of the filled sponges will also affect the service life of the sofa. Coat cutting and sewing The sofa you see, each side is a board, called a leather board. Place the leather board on the cowhide to draw, pay attention to avoiding unqualified leather, and start cutting the leather later. You can also use a blade to cut, of course, if it's fabric, you can use electric scissors, which can cut multiple layers at once. After cutting the leather, pack the sofa cushion, armrests, backrest, and sort them in order to facilitate the smooth and efficient production of the next "sewing" process. Sewing, a flat car, involves joining the cut leather piece by piece. Sewing is a crucial process that affects the appearance and quality of a sofa. Set sofa jacket Cover the sofa with sewn leather or fabric covers. Properly position the sofa according to its appearance and secure it with gun nails. If it is a fabric sofa, hardware such as zippers need to be installed.
