Vamp Stitching Finishing Technology Secret

The meaning is to sort and classify the cut leather, and then complete the stitching for the upper part of the shoe with the sewing machine. It includes all kinds of work contents, many items and different properties. Even the shoe factories also aim at various shoe types, and research and design the secret recipe for the special process.

finishing is meant to make a series of treatments for the pieces of < a href= "http://www.91se91.com/news/index_x.asp > > vamp > /a > before sewing. This work is very important, and it is necessary to check regularly whether the work is done correctly.

When there are any problems in the subsequent molding operations, it is not difficult to trace back to the mistake of finishing work. This is also a factor that a quality control personnel must give priority to. This problem can also reverse the importance of the Department and the possible impact of the problem.

when the size and daily output of shoe factories are very large, it is possible to consider the finishing department independent of the needle truck department, and at the same time having the Department's dedicated QC staff: Although the consolidation department is dependent on the expansion of the shoe factories, it is absolutely helpful from the point of view of quality control, and it can avoid the trouble caused by the unstable quality of the individual technicians due to the different technical skills of the needle workers, and the fear of causing unpleasant feelings among the colleagues in case of returning to the needle truck department.

difficult factories have different methods to send the cut leather to the finishing department. For example, the number of each bundle is calculated in the form of "dozen" or by decimal system. Usually, in order to avoid mistakes caused by confusion, these pieces will be loaded into different sizes with cardboard boxes or similar baskets, especially smaller ones, for example, heel pieces should be bundled to avoid loss, and the quantity of each box is exactly the same as the parts needed for manufacturing, indicating shoe type and manufacturing mode.

In order to avoid wasting time, we should set up a set of system standards, such as the date, time and quantity of the daily report.

quality control

P > before sending all the a href= "http://www.91se91.com/news/index_x.asp" material < /a > to the needle cart production line, it is necessary to check again not only to determine the number of bundles in the basket, but also to be properly installed in the same basket. The person responsible for this product must have a considerable knowledge of the various materials needed to make different types of shoes.

Usually, this kind of quality control work is carried out by the needle truck department, but some shoe factories are held by the cutting department. In order to avoid the gap between the two departments, the quality control personnel must check the quality of all the cutting pieces, and the quantity can meet the requirements.

no matter what mode of delivery, when all the materials are correct, put it in the basket and attach a work sheet. Specify the type, sewing procedure, shoe handling method, line, punching spacing and size, size and even number, etc., must be carefully listed on the work sheet.

< > a href= > http://www.91se91.com/news/index_x.asp > vamp > /a > all parts of the leather and accessories need to be carefully counted before placing them into the basket. Otherwise, when the sewing machine department finds fault, the whole basket should be sent back to the cutting department to reorganize and record the time and date of the delivery. It is not difficult to imagine that if a new piece of leather is to be cut for serious delay, it is no longer easy to find a suitable thickness and color of leather, and it will be more difficult to calculate the time when cutting and re loading the basket.

Before describing the manufacturing steps in detail, it is better to explain the process of sewing: it is possible to declare that a staff can use a needle cart to complete a complete pair of shoes.

But this is not a normal way of doing things. In general, a staff member seams one step or at most two or three steps, and then gradually seams the joints of different parts into a completed vamp.

two identified number .

it is necessary to identify an effective system for identifying the size and fatness of the stitched vamp.

The most commonly used method is color classification. The following will introduce several common systems in shoe factories:

1. crayon notes: undoubtedly, this is the first way to be used.

The size of the back of the leather is marked with crayons, and a material classification sheet is attached to indicate the color and quantity. At least, the type code is written in crayon at the top of each bundle.

2. edge mark: this method is usually used when cutting with chopper. The location of the mark is at the edge of the knot, and the size of the code is set up by the combination of different notches. Similarly, the top part of each sheaf is also marked with crayons, type, fatness, and other necessary data.

3. pigment coating: a combination of different colors to become the representative color of each dimension. Choose the edges of the edges of the edges to be properly painted. If only a small number of orders are used, it is most convenient to use this color classification method. In fact, if the same style has a long string size, this method is also very effective.

Examples are as follows:

men's shoes size: No. 567891011

Color: purple yellow, red, white, blue, green, brown, .

< a href= "http://www.91se91.com/news/index_x.asp" > women's shoes < /a > size: 234567

attention should be paid to the selected parts when painting the pigment, whether the pigments can be concealed or placed on the ends of the stitch after the seams are assembled, without affecting the integrity of the vamp.

4. machine hot stamping: This is the most detailed and costly way to note, especially for the complicated size, the more fat, and the more complicated color orders. This is the most suitable system. Machine stamping can almost indicate all relevant information, such as ruler, fat, number, color, style code.

One, etc., all done in a hot pressing action. This machine usually has a number of revolving hot stamping surfaces, which are heated by electric heating to the impression, and then press the metal dye or colored ink on the leather. This machine is different from the internal hot stamping machine and can not use the foil.

All kinds of colors of ink can be used arbitrarily, hot stamping on different colors of leather, easy to identify, hot stamping position can also be adjusted at any time to adapt to different size of the cutting piece, hot stamping position in the junction or concealed seam position.

To sum up, cutting and adding notes are intended to avoid confusion and delay in the work of vamp combination.

5. internal note .

It is necessary to refer to a brief description of a pair of shoes in the selection of a pair of shoes, which is the most common position of a pair of shoes: the inner part of the rear shoe is the most common position, and some of the laced shoes often include the size, the fatness, the number and the shoe type code. In addition, in order to facilitate the order number and date listed in the order, there is no standard format in the notes, especially the sizes of the labels are more different because of the different sales areas. However, the codes used by different countries are not difficult to understand for the shoe factories and dealers, but the consumers are always confused. not only for the identification of manufacturing, but also for the convenience of consumers.
