The Production And Special Love Of Fashion Handbags Should Be Understood

　　 handbag How to make it special?

　　 Definition of handbags:

The handbags of Shaanyi are the general name of all kinds of handbags that are made of leather and are held by hand. In a broad sense, handbags include: shoulder bags and backpacks with shoulder straps; And the wallet and wallet that you didn't bring with you. In a broad sense, handbags can be divided into travel bags, official document bags, fashion bags, packaging bags, silver bags, waist bags, school bags and leather wallets.

　　 Handbag production:

In short, handbags can be made by sewing. In a word, many skills are familiar. It is related to clothing The difference is that it varies and is irregular. Moreover, most of the raw materials of handbags are thick and hard, including sponge, paper, hardware, plastic and other catch materials or ornaments. From the structural comparison between the two, it is more difficult to make handbags than clothes. For relevant information, please refer to "Handbag manufacturing process" and "Handbag sewing basic knowledge".

　　 Handbags are special:

The so-called exceptional handbags refer to the work of using cardboard as the material, drawing out the shapes of the components of handbags according to the original identification of handbags (or design drawings, photographic drawings), and marking various marks on the components of paper grids to indicate the manufacturing method of handbags. The department engaged in this kind of work is called identification room, and the personnel engaged in this kind of work are called special master or identification room master, or handbag master, or identification.

According to the reference objects, handbags (original identification) or various pictures, make several products that meet the requirements. In the handbag factory, the products are generally provided to the handbag factory according to the customer's requirements, such as physical objects (original identification) or various pictures of handbags. Such provision is the basis for the exceptional craftsman. The identification room is dominated by the exceptional craftsman to re produce several products that meet the requirements, so the identification room is the sample production department.

As the identification room is responsible for sample production, it takes the lead in understanding the production process and technology of products, as well as the total production work and product quality requirements of products. Therefore, Bianfang is the engineering technology department of the handbag factory. Other departments carry out the production cost budget work based on the data such as the product process labor price, raw materials and their quantity obtained from the house identification and in combination with the raw material price.

　　 handbag Exceptional method:

Analyzing the overall structure of handbags, handbags are complex and various in shape. If we analyze them comprehensively, it is not difficult to find that most handbags have such a common structural feature: front, back and large circumference; Left, right and large enclosure; The front, back and bottom materials are three basic components. In some handbags, the front part is composed of several colorful materials, and the front part is also equipped with a flat or three-dimensional front outer bag; The rear frame is also installed; The big wall is divided into the bottom wall and the zipper wall. Two symmetrical side bags are installed on both sides of the big wall. According to the consumer's use, the components other than the above three basic components are increased or decreased, making the overall shape of the handbag varied and complex.

However, no matter how complicated the handbag is, it is difficult to be exceptional. The complicated handbag only increases the exceptional workload, but does not increase the exceptional technical difficulty. The change of handbag shape is difficult to surpass the commonness of handbag structure. As long as we can see the structure of handbags clearly, it provides a premise for us to be special.

The structural commonness of handbags is abstracted from the naked eye through induction and generalization. It is not difficult to find that the structure of the handbag has a rule that cannot be seen by the naked eye alone. The circumference of the width is equal to the total length of its corresponding circumference; The perimeter of the bottom material is equal to the length of its connecting elements.

Analyze the shape of handbag components, including rectangle, square, triangle, trapezoid, prism, circle, ellipse, regular polygon, etc. These are called regular shapes; There are concave and convex polymorphs. The mixed shape formed by mixing several shapes and other shapes that are difficult to name are called irregular shapes.

To determine the shape of regular components, or to link mathematical knowledge. A rectangle can be shaped by measuring its length and width; A square is shaped according to its side length; Trapezoidal upper, lower bottom and high setting; The prism is shaped by two diagonals; A positive circle is shaped by diameter or radius; Ellipses are shaped with large and small diameters. For those irregular figures, coordinate method can be used to fix the shape. Although the shape of the handbag component is diverse, it has the following characteristics: First, it is all planar figures. 2、 Most of them are axisymmetric figures. When a figure is folded along a line, if it can coincide with the other half of the figure, it is called an axisymmetric figure, and the line is called the axis of symmetry.

Since the shape of the handbag components is mostly axisymmetric, only half of the component shape needs to be produced when the paper grid is produced, and the other half can be produced by folding in half along the symmetry axis. This saves a lot of work and time for our paper grid.

When the coordinate method is used for shaping, the plane rectangular coordinate system is formed by two mutually perpendicular number axes with a common origin in the plane. Any point P in the coordinate plane has a unique pair of ordered real numbers (X, Y), corresponding to it; Conversely, any pair of ordered real numbers (X, Y) can determine a unique point in the plane so that its coordinates are (X, Y). Therefore, the plane rectangular coordinate system can combine "number" with "shape".

The handbag is a solid, but the single component that constitutes the handbag is in the same plane. In order to figure out the shape of the handbag component, you can first measure the numbers related to it, determine the points related to it according to these numbers, connect these points with straight lines or smooth curves, and then you can figure out the surface shape of the handbag component. Then, along the edge of the surface shape of the component, use a compass to enlarge the length of a paper opening as a unit to get the shape of the handbag component. This is the principle and method of drafting the handbag component. Components of any shape can be solved by "coordinate method".

　　 Exceptional order of handbags:

First out of the main case, then out of the sub case. The paper grid that can determine the shape or size of other paper grids is called master grid. Subgrid is a paper grid whose shape or size depends on other paper grids.

General handbags, the width is the main case, the circumference is the secondary case; The back frame is the main frame of the front frame; The front pocket panel is the main frame of the front pocket circumference; The side panels are the main panels of the side pockets. The special order of general handbags is as follows: back, front, zipper, front pocket, front pocket, side pocket and side pocket. According to the format sequence, measure the paper grid with a paper grid to figure out the shape of each paper grid, make a triangle notch and a roaring position according to the structure of the handbag, and write various text marks on the paper grid until the paper grid is finished. It should be noted that the length of a paper opening should be added to the paper outlet according to different requirements.

　　 Inspection method of paper grid:

1. Inspection method for the shape and size of the paper grid: fold the paper grid in half along the coordinate axis, and the shape triangle notch should overlap, otherwise, it is unqualified.

2. Inspection of the shape and size of the paper grid: compare the paper grid before enlargement with the actual handbag, and the coincidence degree shall not exceed the maximum allowable error value.

3. Inspection of paper grid triangular notch: mainly inspect whether the triangular notch has completely played its four major roles; Whether the size of triangular notch is consistent.

4. Inspection of matching degree between paper grids: measure the paper grids with paper grids to check whether they conform to the structural rules.

　　 Marks on the paper tray of the handbag:

1. The paper opening of the paper grid; The paper opening is in the paper grid. The paper opening is extra long and invisible from the surface of the handbag. It is used for edge bonding. The more stickies, the longer the paper mouth.

2. Triangle notch of paper grid; Triangle notch in the bag paper grid indicates the marking of the bag making method. It is a Peugeot test for the correctness of a single paper grid. It refers to the inspection of the complete set of paper grids between paper grids. It is a Peugeot for the inspection of the lathe method and its technology.

Different handbags, due to different structures, different paper grid shapes, and different paper opening lengths, must have different positions and numbers of triangular notches. But the triangular notch of the paper grid is the same size.

3. The roaring position of the paper grid; The triangle notch of the paper grid is a symbol that is punched on the edge of the paper grid to indicate the structure of the handbag. Complex handbags, on large components Design One or several bags to avoid the monotony of the design and increase the practicability of the handbag. To determine the position of a bag in the inner part of the component paper mouth, it is necessary to make a roaring position instead of a triangular notch. Determine the location of various hardware and plastic decorations, which is also indicated by the roaring position. Generally, the roaring position of the paper grid should be circled with a pen and marked with its purpose.

4. Text mark of paper grid; The text mark on the paper case, including the article number of this handbag. Name and quantity of paper tray. The cutting method, that is, marking the horizontal or straight grain cutting. Indicate the maximum length and width of this paper grid. It is expressed by multiplying the maximum length data by the maximum width data. Roaring position and part of the three gaps.
