Abstract

A kind of manufacture method of movable shoe-pad of ethylene-vinyl acetate copolymer, system utilizes one or more layers of EVA material to be substrate, then in its surperficial applying one deck cloth cover, through cutting into block unit, with the hot press moulded section of heating, cut according to its shape again, on cloth cover, print suitable pattern at last according to need, promptly finish a kind of appropriate flexible shoe-pad that has, be applied to the shoe-pad of sport footwear inside or as the heelpiece of beach shoe or slippers with it, give the elasticity of appropriateness such as sport footwear or beach shoe, promote the comfort of dress.

Description

The manufacture method of movable shoe-pad of ethylene-vinyl acetate copolymer

The present invention relates to a kind of manufacture method of article of footwear, specifically, is a kind of manufacture method of adjustable shoe pad.

Shoes are a kind ofly to contact the most frequent article with human foot, need and have the shoes of different functions to be designed and use according to different situations, sport footwear such as the leather shoes that are fit to the formal occasion dress, suitable motion dress is fit to the slippers of dress at home and the beach shoe that designs in order play with water in the seabeach etc., the common purpose of these shoes is the security protection to foot, makes foot be subjected to suitable protection; Yet progress along with growth in the living standard and industrial technology, human requirement to shoes except need possess the basic function of security protection, further requires its wearing comfortableness, and how to promote the snugness of fit of shoes, just become the target of being engaged in footwear manufacturer active pursuit.

Generally speaking, whether comfortable and easy to wear shoes are, except the quality of using material, the design of shoe-pad more is related to wearing comfortableness, because of shoe-pad is the member that contacts with sole, and between walking or race jumping, whether the active force that foot and ground are produced can be entirely shoe-pad is offset, the active force that bears for foot has great influence, if the two active force of foot and ground can't rely on the shoe-pad counteracting, must cause the injury of foot after then long-time, otherwise absorb counteracting if the active force of the two can be shoe-pad, then its dress must feel comfortable; Early stage shoe-pad polyphyly utilizes the bonding one deck plastic cement of nylon blending cloth surface to form, because its shortcoming elasticity, its effect only is to block foot and contacts with the footwear substrate, and not helpful for promoting wearing comfortableness.

The purpose of this invention is to provide a kind of is the shoe-pad making method of substrate with the EVA material, by the resilient characteristic that the EVA material is possessed, makes shoe-pad have splendid elasticity, to promote the comfort of dress.And utilize one or more layers of EVA material to be substrate, and the different-thickness of shoe-pad is provided, make its shoe-pad that can apply to sport footwear inside or as the heelpiece of seabeach or slippers.

After the EVA material foaming that the inventive method system utilizes is one or more layers (promptly one deck) at least, as substrate, at its surperficial applying one deck cloth cover, after cutting into block unit, insert the moulded section of heating in the hot press, cut according to its shape again, and print pattern on cloth cover according to need at last, and make the footwear that are suitable for the different application occasion, promptly as the shoe-pad of sport footwear inside or as the heelpiece of beach shoe or slippers.

Accompanying drawing of the present invention is as follows:

Fig. 1 is the synthetic schematic diagram of the multi-level material of the embodiment of the invention.

Fig. 2 is the schematic diagram after the embodiment of the invention moulding.

Fig. 3 is the shoe-pad stereogram after the embodiment of the invention cuts.

Now conjunction with figs. 1～3 provides a better embodiment, and manufacturing process of the present invention is described in detail in detail:

In the method for making of the present invention, system with one or more layers of EVA material through the foaming after, with it is substrate, as shown in Figure 1, it is to utilize two layers of EVA material layer 10,11 are substrate, a layer cloth cover 12 pressed in surface applying one thereon, then insert in the hot press through cutting into block unit 13, through heating, pressurization, utilize the completed state that mould extrudes to be become as shown in Figure 2, and according to its thickness difference, in the forming process of heating, temperature range is by 150 ℃～180 ℃, need adjust it, the shoe-pad embryo 20 after the moulding by 20～45 seconds according to it heat time heating time, 21 are cut according to its shape with die again, last printing or the suitable pattern of transfer printing on cloth cover are according to need promptly finished shoe-pad finished product 30 shown in Figure 3,31.

With the made shoe-pad of method for making of the present invention, use by the EVA material, give the elasticity of shoe-pad appropriateness, increase wearing comfortableness, further utilize the variation of its substrate number of plies and the printing of cloth cover pattern in addition, make its scope of application except the shoe-pad that is used for sport footwear inside, more can extend to heelpiece, significantly improve the value of its practicality as beach shoe and slippers.

Claims

1, a kind of manufacture method of movable shoe-pad of ethylene-vinyl acetate copolymer is characterized in that:
