Net height, net length, net width does not include the actual height, length, and width data of the edges such as hemming, embedding, and seating.

The shape line draws a virtual line of the size and shape of the package body in advance on the paper grid. From the virtual line, you can see the approximate appearance of the bag entity.

In order to make the tooth mouth easier to align or emphasize the position, a small triangular incision cut on the paper grid, the incision depth is about 0.5 minutes.

Folding is a process in which a certain width is added to make the edge of the part not reveal its material, and then folded and bonded. The added width is usually 2.5 minutes.

The overlapped part and the part that needs to be seamed and placed on the lower side of the part to be covered, its width is 2.5 minutes.

The anti-car parts and parts need to be stitched on the back of the material, and the edges of the parts and parts are the same type of stitching (the front side of the material is invisible), and the extra width is 2 minutes.

 The two edges at the refuted notch are stitched back on the back of the material, turning from a flat surface to a three-dimensional sewing process. The extra side position is 2 points.

Embedding two parts of different shapes requires a sewing process in which they are stitched together on the back of the material (the face line cannot be seen on the front of the material), and the extra width is 2 minutes.

The edge joints of the two parts of the turning line are turned on the back of the material, and a face line is sewn on both sides of the center line on the face of the material to beautify and strengthen.

In order to prevent the edge of the part's cut from being exposed, the oily edge is directly painted with edge oil on the cut to achieve a manufacturing process that covers the material of the stubble and beautiful the cut.

Hemming In order to prevent the edges of the parts from being exposed, a long strip of material is directly used to cover the edge of the incision and stick and press the seam. In order to make the package body more stiff and shaped, the side bone is wrapped with a rubber core or a steel wire core in the middle of the bundle, and it is clamped and fixed when it is buried. Most of the side aggregates are 6 minutes wide (the width of coarse aggregates is different).

 Commonly used tools are utility knives (or straight steel knives-use a wider blade to grind a fractured blade), steel rulers (often with inch scale and metric scale, 12 inches and 24 inches in length), tape measure (Soft ruler), awl, compass, ballpoint pen, pencil and 250 grams of white cardboard. A complete piece of paper is mostly symmetrical. Therefore, you must first find a central axis when you are out of the box, so that as long as you cut one side, you can get two symmetrical edges. The central axis is cut on the cardboard. When cutting, press the middle of the steel ruler with the fingers of your left hand, and hold the utility knife with your right hand so that the angle between the blade and the jammed paper is about 300, and then gently cut along the outside of the steel ruler to create a straight line. The shallower notch (but not through the jam) is used as the central axis. Fold back the central axis to find a point, then spread out the jam, and connect the symmetrical points on both sides of the central axis to cut a straight edge. When some paper grids are not only symmetrical, but also symmetrical up and down, it is necessary to add another central axis in the vertical direction of the first central axis, which is what we often call crosshairs. The method is to draw the first central axis in the shorter direction of a piece of irregular blank cardboard, fold it, and then pierce both sides with the tip of a knife at a place farther away from the first central axis and tends to the middle of the central axis. Find the corresponding points on the layer of jammed paper, then spread the jammed paper, connect the two corresponding points with a steel ruler, and cut and draw another central axis. The two central axes intersect perpendicularly, and there is an intersection in the middle. In this way, you can find points for cutting according to actual needs. If you want to make a standard and perfect paper grid, you must not only skillfully use a steel ruler to cut straight, but also practice the cutting of arcs and bends.
