Abstract

The present invention relates to a manufacturing method of synthetic leather shoes insteps, which is mainly to solve the deficiency that the manufacturing operation is miscellaneous, the labour cost is enhanced, and unqualified products are easily produced because the shoe instep patterns in the traditional technology are manually folded and sewed. The method comprises that synthetic leather is cut, and is pressed for forming to form predetermined shoe instep patterns; next, the synthetic leather is sewed to a shoe instep; then, a shoe tree for wrapping is taken out through machining procedures of wrapping, internal wrapping in a sew, affixing of undersole, etc.; Each leather shoe with a synthetic leather shoe instep is obtained, and the leather shoe has the advantages of easy manufacture, labour cost economy and enhancement of production rate.

Description

Manufacturing method of synthetic leather shoes instep

The relevant vamp manufacture method of the present invention refers to a kind of manufacturing method of synthetic leather shoes instep that reduces cost, boosts productivity especially.

Along with economic, cultural development, shoes, clothes more become the indispensable article that beautify modern's life.China have the good reputation of " footwear kingdom ", China's now in non-in the past labour-intensive epoch, the footwear manufacturer is devoted to the improvement on manufacturing technology and the flow process invariably, in the hope of haveing breakthrough, yet the footwear of commonly using all adopt sewing to make, the formation of all decorative patterns all is that vamp is cut into polylith on its vamp, amounts to by craft and gives sewing.Since be subjected to feet shape, curve restriction, vamp decorative pattern the process of amounting to usually system with vamp be divided into toe-cap, edging, back cover, after roll mouthful and parts such as flap, leaning on one by one, order-picking trucks is sewn into, cause because of process is numerous and diverse that the processing cost expense improves, speed of production is slow, and easily produce the defective work of flaw, in addition, because of need are cut into polylith with vamp, its kind accessory is extremely many, give in buying and the stock control down and all will bring puzzlement, be not inconsistent the principle of increasing economic efficiency in fact.

In view of this, the long-pending practical experience of being engaged in footwear manufacturing and research and development for many years of the inventor, several times trial-production, and this synthetic leather leather shoes face manufacture method is proposed.

Main purpose of the present invention is to provide a kind of synthetic leather leather shoes face manufacture method, only needs vamp is cut into single block, and is therefore easy to manufacture, can save artificial and material cost, and can boost productivity, reduce disqualification rate.

Comprise following step according to a kind of leather shoes face manufacture method provided by the present invention:

1. get the thick slightly synthetic leather of a thickness.

The shape of 2. looking whole vamp cuts into single one with size with above-mentioned synthetic leather.

3. follow, above-mentioned synthetic leather through cutting is given moulded section, form predetermined vamp decorative pattern.

4. the synthetic leather sewing after the moulded section is made a vamp.

5. impose the wrapping program again, the vamp that sewing is formed is tightened on a shoe tree, and forms a fixing footwear shape.

Make the vamp of finishing by above-mentioned steps, again through sewing, in wrap up in and paste the big end after, can obtain the leather shoes of a synthetic leather shoes instep.

Now also elaborate in conjunction with the accompanying drawings by an embodiment, can be to above-mentioned purpose of the present invention, for reaching technology, means and the effect thereof that above-mentioned purpose of the present invention adopts, feature and advantage thereof can obtain deeply and concrete understanding.

Fig. 1 is that the synthetic leather of one embodiment of the invention cuts schematic diagram.

Fig. 2 is the synthetic leather moulded section schematic diagram of one embodiment of the invention.

Fig. 3 is the synthetic leather sewing schematic diagram of one embodiment of the invention.

Fig. 4 is the wrapping schematic diagram of one embodiment of the invention.

Fig. 5 is the schematic diagram that completes of one embodiment of the invention.

Now see also accompanying drawing, synthetic leather shoes face manufacture method provided by the present invention comprises following steps substantially:

(a) get the synthetic leather (10) of a suitable thickness, the leather that the thickness of this synthetic leather (10) is commonly used usually is thick, for an effective mold pressing degree of depth is provided.

(b) above-mentioned synthetic leather (10) is looked required vamp size and given integral body and cut, make vamp only be one single (shown in first figure).

(c) then, the above-mentioned synthetic leather that cuts (10) is given compression molding, form predetermined pattern (as shown in Figure 2).

(d) synthetic leather after the compression molding (10) is given sewing and form a vamp (11) (as shown in Figure 3), thread (11a) position is the suture of vamp (11).

(e) apply the wrapping program again, the vamp (11) that sewing is formed is tightened on a shoe tree (20), forms a fixing footwear shape (12), processes (as shown in Figure 4) for next flow process.

(f) with above-mentioned fixed-type footwear shape (12) again through sewing, in wrap up in and paste at the big end etc., then take out this shoe tree (20), can obtain the easy to manufacture and synthetic leather shoes musculus cutaneus footwear (as shown in Figure 5) that can reduce cost and boost productivity.

Now advantage of the present invention is summarized as follows:

1. no matter the footwear type of any complexity, the cladding that need only order single specification gets final product, thereby convenient buying and stock control, thereby has reduced the cost of labor management.

2. every pair of shoes only must cut 1-2 position, so management easily, almost do not have the loss on the cladding, and each footwear type need only prop up die by 1-3, can reduce the expense on the die.

3. the decorative pattern because of vamp is compression molding, therefore, can simplify manual process, but have the effect in the same craft, and speed of production is speeded.

4. making needs the car vamp of pin seam seam to occur over just the 2-3 position, so speed of production is speeded.

Stay in grade, can reduce the generation of defective work, thereby increase the competitiveness in market greatly.

In sum, the manufacture method of the embodiment of the invention is utilized the simplest, effective operation, makes vamp manufacturing process simple and easy, escapable cost, boosts productivity, and obviously has value on the industry.

Claims (2)

1, manufacturing method of synthetic leather shoes instep, comprise earlier the synthetic leather sewing is become a vamp and forms the securing footwear upper shape after, in sewing, wrap up in again and paste at the big end, it is characterized in that:

The shape of this synthetic leather being looked whole vamp cuts into single block with size, and then impose compression molding, to form a predetermined vamp decorative pattern, after the synthetic leather sewing of compression molding is formed a vamp, and impose the wrapping program, the vamp that sewing is formed is tightened on a shoe tree, promptly forms a fixing footwear shape after extracting shoe tree, thereby finishes the manufacturing of synthetic leather shoes instep.

2, manufacture method according to claim 1 is characterized in that for an effective mold pressing degree of depth is provided, and the thickness of this synthetic leather leather thickness of usefulness more usually is thick.
