Description

[Detailed description of the invention] The curse is rising! The shoe manufacturing process is generally very labor intensive and The most expensive element in today's manufacturing process is labor. For a particular style of shoe The pattern is created in all sizes and the manufacturing schedule is adjusted during the production stage. After this is determined, a labor-intensive assembly process occurs. Specific designs and features The assembly process for a shoe with a fixed number of components begins with the cutting process of 9 leather materials. shoes As patterns become more complex or the number of design elements in a shoe increases, so does material waste. In order to minimize this, a more careful design of the cutting means is required.

In the normal shoe manufacturing process, after cutting a piece of cowhide, such components are Preparation for suturing is made in the sewing process. The cowhide pieces are first marked for stitching. Ru. For the ends of pieces that are sewn to other pieces, the machine will The thickness must be reduced during the skiving process to cut the beveled edges. , Certain or all 9 leather parts (especially thick cowhide leather) can be removed using a "back-sliding" machine. It is necessary to reduce the thickness or make the thickness uniform using a machine. Each such stage includes , requiring the handling and skilled manipulation of individual pieces of cowhide to make the desired changes to the cowhide. Ru.

In the normal process, a piece of cowhide is prepared by skiving and back plowing, and then Doubling to add texture and improve the interior comfort and smoothness of the shoe In the doubting process the core is glued to the cowhide. This process includes Careful alignment of the core and cowhide is required. Further improves comfort and adds strength. For this reason, the inside of the seam is often rubbed with adhesive to reduce its bulk. Reinforce this with cloth tape coated with. Cloth tape similar to this is used for shoe openings. It is also used for the edges of cowhide leather. such upper edge as well as any other recognizable edge; For each end, fold it thinly to improve the appearance of the end, and then fold the folded part again. Adhesives may also be used before heat bonding or suturing.

If the shoe has a clasp, the holes should be drilled, spaced and aligned, or This is applied by a machine that places the objects in the appropriate locations. and the subsequent stages The grommets are mechanically fastened to secure the components in the correct position.

The cowhide pieces may be removed after the fitting process or at the fin tip, depending on the production stage of the particular shoe. sutured during the sewing process. The suturing process can be done by machine or manually. , may also include reinforced stitching and decorative stitching at the front corners of the Führer. subordinate In the final stage of the manufacturing process for modern shoes, the cowhide is then molded into a shoe last (a shoe shaped in the shape of the foot). mold). Assembling the cowhide and core on the shoe last and fixing these with the insole Various lasting techniques can be used for this purpose. In this process, the cowhide heel of the shoe is and the appropriate positioning on the last so that the toe and side parts take the desired shape of the finished shoe. It is placed while applying tension to certain parts. After that, the cowhide of the shoe is subjected to The shape is maintained for several days in order to fix the shape.

Alternatively, the shape of the cowhide can also be fixed by a heat fixing process.

The sole of the shoe is added in a "soling" process by gluing, molding or stitching. stop then add shoelaces, box the product, and store it in the warehouse.

Hatsurabe Overview The present invention provides several functions (close fitting or sealing of edges, contours for shape retention). Functional design or patterning to promote stretchability for shaping and strain control (including, but not limited to, the incorporation of turn lines) A shoe component is provided that includes a bossed multi-layered material. Embosocin The embossed material adheres to the material layer at the edges and increases the thickness of the material at the embossed area. Reduce. One of the layers of the multilayer material is heated or otherwise subjected to melting energy. Build up viscosity to the point where internal adhesion of the foam cell matrix is achieved when It is a porous foam member that is highly breathable.

A shoe component refers to any of the many different elements of a shoe, its possible configurations. Elements include the entire 9 hides or overlay portions of 1 herb.

Components of the shoe may be made of raw material, such as embossing to promote a design or pattern. Embonosing can also be done at locations other than the edges of the material. Embossing helps control the shape and texture of shoe components, and also helps to control the end Useful for adjusting certain distortion factors in use applications.

The invention also provides a method of fastening parts of a shoe. This method is suitable for shoes. including minute alignment and insertion of the thermoplastic connector into the material of the shoe part; Expose the sexual connector to sufficient energy to soften it.

The shape of the connector is such that when it hardens, its new shape prevents the parts of the shoe from separating from each other. Transform to

The first thermoplastic connector is inserted through the second thermoplastic member and the aligned portion of the shoe. can. The connector melts the two pieces of connector to the point where they adhere to each other, thus forming a part of the shoe. Can be exposed to a high frequency electromagnetic field with sufficient energy to fix the minute Ru.

implementation spot The present invention relates to a method for manufacturing shoes and shoe components, and a method for manufacturing shoes and shoe components. Consists of shoe components.

Most types of shoes can be made by the method of the invention, for example, fastening of flats. Instrumented shoes can be made using the process of the present invention. Additional decorations or cuts You can also add woodwork to the basic patterns presented.

As shown in FIGS. 1 and 2, the cowhide 10 may consist of multiple layers. Preferably, a three-layer construction is most preferable, with additional layers added for durability or strength. You can also add. A process known as a bonding method that is well known in the footwear manufacturing industry. The steps are used to secure the fabric layer to each side of the core 12 layer of the foam member. can. In a preferred embodiment, the layers are secured with a neoprene (chloroprene rubber) adhesive. I'm wearing it. Place the bottom sheet (back side) inside the mold, apply adhesive to the entire surface, A layer of foam material is placed on the backing. Finally, in another preferred embodiment, the layer is thermosetting. It is fixed with a cross-linked S structure. However, thermoplastic resin Plastic adhesives may also be used at temperatures above the processing temperatures associated with other components of the material. This can be used provided that dissolution occurs when Also flame laminated Technology can also be used. This eliminates the need for adhesive altogether.

A preferred core material 12 is ether-based (i.e., polypropylene rubber). Recall) This is a polyurethane foam product. This is a mixture of water and catalytic material. Obtained by processing with sosoanate. A suitable foam member has a density of 1.5. 4, Olbs/H, but the generation of densities above and below this Foam components have application in certain end-use categories. Many foam core materials is composed of variations within the polyurethane system. Polyurethane Group Other materials, primarily rimmer, can also be used as core materials.

Preferred implementation L! In one type, the outer layer is classified as ``tricot''. The fabric is made from scratch. Such terms are used for a fairly wide range of products, including: Some can be used in the shoe molding process, while others cannot. In particular, full Two types of bar knits, such as tricone and warb rock knits, are processed through the forming process and finishing process. It has particularly good qualities when it comes to natural use.

In another preferred embodiment, the outer layer has a name such as chassis, ridge or km. Use rice cake dough. The deformation of the chassis depends on the dimensional equality of its elasticity. Therefore, it has particularly excellent properties. Many other variations of the weave cloth are also produced by It has been successful during the process and in end use.

In another preferred embodiment B, the outer layer is made of woven material, and woven fabric is used in the assembly process. When using However, while the major characteristic of W fabric is the stretchability or elasticity of the fabric, woven fabrics are Low elasticity due to some one-dimensional relationship between fabric and yarn width/length; Therefore, when using textile materials in the process, focus on the stretch properties of the yarn. is required. The method of adding elasticity to yarn is well known. , including the use or interweaving of composite or bicomponent yarns or fibers. Can be done.

Another preferred embodiment uses an outer layer made from a product of leather type. mosquito As the leather, animal skins such as cow, calf, bull, water buffalo, and pig can be used.

The animal skin is tanned in a method for producing leather products that can be used in the shoe assembly method of the present invention. can be done. Considering the durability of general leather products, we recommend using leather wisely. The properties required for this purpose are multidirectional expandability that suppresses loss of basic strength properties such as tearing.

As an example of an application, this can be used to tear animal hides relatively thinly (0.4 to 0.6 mm). and overlaying the resulting sheet over a substrate of substantial properties. This is achieved by Substrate selection depends on the final component requirements.

In another preferred embodiment, the outer layer is polyurethane, PvC or synthetic rubber (cellular or in solid form). on fabric substrate Industrial processes can be used in the assembly of products that use synthetic leather or coatings. . There are two such methods that are widely used in the industry: [wet] and “dry” methods. It is. Such materials are low cost and produce a wide range of physical properties and appearances. can be processed in a variety of ways.

Considerations governing the selection of inner and outer layer materials include whether the outer layer is emposable; This includes the following points. This includes scorch resistance to heating but does not require stamping. ability to maintain the shape associated with the foam layer; sufficient tearing of one or both layers; strength, comfort of the inner layer, durability of both layers, appearance of the outer layer, and flexibility of both layers. Needed.

Cowhide 10 is cut from embossed and laminated material using various methods. Cut off. These are standard blade dies, knife-cut dies, dual-function Molding/mold methods, automatic vertical mold cutting, automatic roller mold cutting, automatic laser methods, and and template/guide automatic cutting. mold or ten The plate is designed for cutting either one piece of cowhide or multiple pieces of cowhide at a time. It's okay.

One example is shown in Figure 9 on a cutting die or template guide. 4 9 leather patterns with 18 spacings that make it look like a cowhide original pattern This allows combinations of different parts and minimizes material waste. Generally mold and almost Square materials of the same size are used. After embossing, The embossed sort is removed from the mold and the shaped cowhide is cut from the square material. It will be done. A mold with a number of cavities was provided with a template guide. Guyang cutting dies are commonly used.

The shape of cowhide 10 is limited by the shape and size of the foot, but it can be used in various styles. I can design shoes for. As shown in Figure 3, when viewed from one side of the shoe, 1 The shoe cowhide 10 is made of a single piece of leather, starting from the first center dorsal side 20 of the cowhide, to the first shoe side surface 22, to the first front side. section 24 and the toe section 26, and the second surface extends from the cowhide toe section 26 to the second front surface. 28, the second shoe side 30 and the second back side 32 are mirror images of the first side, and the "0 character" is formed. It extends in a 1 or 7-character shape. The broken lines in Figures 4 to 7 indicate the shape of the shoe. It shows the center line of each face, which is generally a mirror image of the other faces. The difference on the side is , the side surface 22 or 40 of the shoe that is the inside of the foot is the last of the side surface of the shoe that is being offered ( make the cut shallower or make other changes to assist in conforming to the last). It is to cut this by adding . The strap 34 is attached to the side 22.30 or Extends over the top of the foot to communicate the front part 24.28 (Figures 3 and 4) , or straps 36 (Figs. 5 and 6) or other Straps from the sides can be provided. Cut off the 10 pieces of cowhide leather on the middle of the legs. It is also possible to be solid without providing a partial 3 day, and also without providing a strap. It is also possible (Figure 7).

Before cutting (trimming) the layered material, the design 40 is grained onto the material and the edges 42 The material is then put through a heated molding press to flatten it. Embossing process heats and melts the edge seams including 448 of cowhide leather, thereby sewing the edge seams. The multiple materials are completely bonded together without joining, and therefore the cowhide is made from a single piece of leather. allows for an economical use of manpower.

Embonosing 40 at toe area 26 and front area 24.2 (Figure 3) This helps maintain the boxy shape of the toe, and the edge on the strap 34 also helps maintain the boxy shape of the toe. The embossed lines 40 also help curve the strap over the midsole of the shoe. It is. Create the desired shape by adding more emponons. Increasing the stiffness of the cowhide leather in shoes so that it can maintain its properties. All embonosing is art It may be a shape. The end 42 lasts during the last process (on the last). It is a lasting green used for embossed on the shoe A logo can also be placed on the shoe in the logo portion 41. Any part of the shoe You can also create your own design.

In Figures 3-7, various side designs are shown. design extends over the strap 34 as shown in FIGS. 3-4. Can also be done. Cotton or leather, etc. for forming cowhide leather for shoes consisting of a three-layered laminate heat melting and melting of natural materials, as well as nylon, polyester and other synthetic materials. Embossing and embossing are unique and important aspects of the invention.

Furthermore, emponosing is useful for adjusting distortion in end use. . Embossed lines are used extensively in creating designs and patterns Therefore, these points can be used or become part of a design pattern. It is possible to add additional points. This embossing can be done by Blast rate I! The length of the upper material can be changed by locking off the length of the fibers. Helps control distortion. This technology applies to areas where pressure and related strain occur. shoe designers by allowing extensive adjustment of specific properties in , which provides unlimited control over the end-use dynamic properties of shoe cowhide leather. It is useful for many things. For example, basketball shoe tops with appropriate functionality. The collar, when fully fastened, feels comfortable around the lower leg of the wearer. It is well known that objects expand and contract until they fit properly. however , the part of the shoe known as the inner/outer lumbar, when properly treated, It requires far less stretch characteristics than the top collar. Are listed By using the method, the shoe designer can engineer specific aspects of the shoe design. can be made more effective. This method allows functionality to be incorporated into the shoe during the assembly stage. I can do it.

A normal embossing mold 100 used in the process of the present invention includes an upper press plate 1 06 against the lower press plate 108 (the mold 110 is installed between them) (Figure 10) consists of hydraulic flips 102 and 104.

Both breathers vi106.108 are provided with heating elements 112 and 114. There is. Heating elements 112.114 heat the press plates 106.108, resulting in The lower molded plate 116 and the lower molded plate 118 are heated to a desired temperature.

The important point is that during the forming process, there are differences between the upper press plate 106 and the lower press plate 108. temperature settings. This allows the lower part to be molded during the same molding process. Creating a height difference between the temperature of the plate 116 and the temperature of the lower molding plate 118 of the mold 110 This allows for more heat-sensitive materials such as thermoplastic urethane or PVC can be used on one surface.

For example, Figures 11 and 12 show the images before and after the embossing process. FIG. 3 is a partial cross-sectional view of the mold 110 and the middle curtain during the molding process. In the perspective view of Figure 13 The use of mold alignment bins 120 and mold pin alignment holes 122 on the forming plate shown is , allowing proper alignment of the forming plates 116,118. The outer layer 14 is exposed to heat such as PVC. If the material is sensitive, the upper forming plate 116 may be heated above the softening point of the layer 14. The forming press plate 106 can be set at a low temperature to prevent this. lower molding plate The temperature of 118 is selected to achieve proper thermal melting of layers 14 and 16 into foam core 12. In some cases, it may be necessary to increase the temperature of the upper plate 116 to compensate for the decrease in temperature. In some cases, it may not be necessary. After the desired heating time, the upper press Fi, 106 is turned on. Salvage and remove emboss song method 110. Embossed and molded inside The curtain is removed and the middle curtain is made of polyurethane, ready to be trimmed of excess material. The preferred method of the present invention using tongue foam members involves heating at 200 degrees Celsius for 3 minutes. A thermal cycle is used.

This temperature is the appropriate temperature to achieve internal cell wall adhesion when there is molding pressure. degree. Such adhesion increases the viscosity of the cell matrix to the point of creating internal connections. This occurs as a result of the applied heat and pressure. This internal concatenation is Achieve the installation of the ringing part. Heating the foam member to a temperature below its melting temperature However, the embossed part is referred to as the dissolving part here. combination with foam parts I! of leather products, natural and synthetic fibers! material, as well as PVC or polyurethane Synthetic materials can undergo this heat treatment without distortion or impairment of their original physical properties. can withstand reason.

Alternative embossing methods include non-porous or discontinuous and highly Possesses the necessary properties to enable embossing upon exposure to frequencies Ultrasonic or high frequency welding for certain embossing materials such as plastics and glue Can use technology. High frequency heating uses a transformer to increase the main voltage, alternating current Rectifier to change to DC and it more than about 28 million cycles per second produced by using an oscillator valve to stop and start at speeds of Ru.

Radiofrequency heating eliminates the waiting time required for heat to propagate from an external heating source to the internal material. It differs from radiant and conductive heating in that the temperature rises uniformly through the material. present invention In the use of high frequency heating in set up). When exposed to this region, the movement of molecules in the middle curtain , and uniformly generates frictional heat throughout the middle curtain.

As a result of the use of pressure from the protruding parts of the mold in addition to the high frequency range, the produces an embossed design. In addition, the mold has a raised area around the outside work and 7th ji. By providing an edge, it can also be used to cut the outer edge of the middle curtain.

In addition, high-frequency welding using a welding mold melts two pieces of material, such as the two back ends of the middle curtain. or to add additional components (tongues, trims, buckles, etc.) to the middle curtain. You can also use this for High frequency (HF) i-contact is especially suitable for passing through materials such as PVC. It also allows the dissolution of colored pigments or appliqués into the embossing method. It is something.

After the middle curtain 10 is completely embossed, as shown in FIG. Thus, the back strip 44 is attached to the middle curtain 10 using known stitching methods. Attached to the dorsal side 20.32. Back strip 44 is no more than three-eighths of an inch and 1/2 inch wide, forming a crease 46 at the upper edge 48 of the shoe 50 to secure the shoe. It has approximately twice the length of the credit card so that it can be sewn on both the inside and outside of the back seam. It can be a straight strip of cloth. Moreover, the bank strip 44 is It can also be provided only on the outside of the shoe 50. In addition, the color strip 40 is and/or may also be decoratively designed in shape. hack strip If 44 is not used, either the dorsal sides are overlapped and sutured, or both sides are heated. Other methods of gluing the back side of the curtain can be used, such as embossing.

In accordance with the method of the present invention, the shoe 50 is manufactured using any of several conventional techniques. Last. Preferably the simplest and least expensive of these techniques. Therefore, it is preferable to use cold-adhesive lasting, but California Lasting (Full Sock Lasting) can also be used. The insole board used is Non-woven, cellulose-based fiberboard made by conventional techniques is preferred; It can also be manufactured from other hard or soft fiber lasting boards.

The hook liner is preferably a rubber sponge with a tricot surface, but A cushion material whose surface is made of any fabric may be used. When the shoes are last, Lines A and B are aligned within the shoe with the strut 34 (FIG. 5).

After attaching and lasting the hack strip, attach the sole 52 of the shoe. (cementing method is preferred), due to its low cost and simplicity. It is preferable to use room temperature cementing. The sole 52 is of a type known to those skilled in the art. Manufactured using ethyl vinyl acetate (EVA) molded using However, it is desirable to use cut EVA (cut EVA) as thermoplastic rubber. It can also be used in the same way. Other methods of attaching soles that do not involve gluing can also be used. These require "direct bond" polyurethane or thermoplastic rubber Ru. Both of the latter techniques require shoes made by California Lasting.

Preferred embodiments of the present invention include vertical stockinette, horizontal stockinette, textile fabrics, and leather products. Alternatively, it involves the creation of a three-layer inner curtain having an outer layer of synthetic film material. The middle layer of the material is polyurethane foam, and the internal liner can be made of any of a number of materials. The laminate may be heat embossed for about 3 minutes at a temperature of 200 degrees Celsius; After that, the back side of the middle curtain is fixed by suturing with the back strip. and always The midsole is lasted and attached to the sole by hot adhesive or other conventional means.

1. Regarding the middle curtain of pasture, as mentioned above, using the heated embossing method, can be used to create many different shoe components. Heat embossing of shoe components Sourcing is decorative and at the same time functional in many ways.

Regarding multilayer materials with layers of porous foam materials such as polyurethane foam , the heat and pressure of heated embossing allows the resulting tack to achieve adhesion. selectively creates viscosity in the internal cell wall matrix to the point where it is suitable for . Therefore, when heated, the polyurethane foam adheres to the surrounding material. Becomes a strong adhesive. Materials with a foam member in the middle layer between two outer fabric layers For the present invention, embossing helps to tightly seal the three layers. The shoe components are embossed along the edges, thus sealing along the edges, so they are No edge stitching is required to join the material layers.

Another feature of heated embossing is to reduce the thickness of the material in the embossing area. That is. Shoe components are often joined at the ends, so interlocking shoes Avoid forming unusually thick parts of the shoe where components overlap Therefore, it is desirable to make the edges relatively thin compared to the rest of the material. Delicious. Heat embossing along the edges of shoe components reduces edge thickness This thin section is obtained without the need for skiving, the traditional method for .
