1. Flat setting
The flat inlay process is generally used for flat inlays, and the inlays are no longer sewn when used in the box. Therefore, it is required that the inlays be firmly glued. Generally, neoprene with good viscosity is used. Before splicing, cut the edge pieces of the parts into a slope shape, the upper pressure piece is mesh layer, the lower pressure piece has a grain layer, the slope should be flattened, and the width of the slope on both sides is equal, and coated with neoprene after cutting. Glue; flatten the sides to join. Such as the splicing of the walls and strips of various leather suitcases, the fabric parts of the instrument box, instrument box, medicine box, cosmetic box, jewelry box, etc. of the wooden box.
The advantages of flat inlay are: the joint at the inlay is flat, the surface is smooth and flat. At first glance, the surface is almost one.
2. Stubble splicing
Stubble splicing is when the edge of one part is pressed over the edge of another part. The stubble splicing process is generally used for the connection of luggage and leather bag parts. Such as the connection between the trunk, the surface of the leather bag and the bottom, the connection between the wall panel and the horizontal head, etc.
Before pressing the stubble, the edge of the upper pressing part should be trimmed. There are two types of edges for stubble stitching: one is "smooth edge" and the other is "burr edge". Which edge to use depends on the needs of the product. After trimming the edges, apply adhesive to the edges of the upper press. Then press the edge over the edge of the other side to connect the two parts.
The characteristics of pressing stubble splicing are simple process, convenient operation, firm splicing and obvious edges.
3. Docking
Butt joint is to bring the two parts together on a plane on both sides without overlapping in the middle. Before joining, cut the thick slices along the edges of the two parts evenly, and cut the edges straight with a knife. When joining, put the two edges together into a straight line, and glue a piece of lining under the seam. The lining can be made of leather or fabric to enhance the joint strength.
Butt joint is characterized by simple process and flat joints.
4. Press seam stitching
The process steps of pressing seam stitching are: first butt the edges of the two parts on a plane, and then cover the parts or decorative parts on the seam to hide the seam, especially for leather fabrics, this method can make the seam invisible. It is convenient to cut materials and improve the utilization rate of leather, which is a method often used in the design of luggage products.
Before splicing, poke the center eye on the lining to draw a line, cut the edge of the butt evenly, and cut evenly on both sides of the pressed seam. If burrs are used in the seam, it is only necessary to cut the edges evenly, and if the edge is used, it needs to be cut according to the edge-folding process.
When splicing, first coat the adhesive on the lining, and compound the fabric to the lining. On the middle, align the drawn lines on both sides, bond the fabric firmly, and then coat the mesh layer of the pressed seam with adhesive. The seam is compounded to the seam. The characteristics of pressed seam stitching are that the seams are hidden, the joints are firm, the cutting and reclaiming are convenient, the fabrics are saved, and the surface of the finished product has a strong artistic sense.
