Abstract

A one-piece-vamp manufacture method includes: (1) weaving preparation: arranging different required raw material color yarn, hot melt silk and stretch yarn at a main color opening yarn feeding orifice, a match color opening yarn feeding orifice and a stretch yarn yarn feeding orifice; (2) weaving U shape tube fabric: a vamp machine weaving in an order of a starting opening, an outer toe cap, an outer shoe body, an outer heel, an outer shoe opening to an inner shoe opening, an inner heel, an inner shoe body, an inner toe cap; (3) stitching an inner toe cap stitch eyelet; (4) stitching the outer toe cap stitch eyelet; (5) forming a one-piece-vamp semifinished product; and (6) reshaping, setting and shape fixing.

Claims

1. A one-piece-vamp manufacture method comprising the following steps:

(1) weaving preparation;

arranging different required raw material color yarn, hot melt silk and stretch yarn at a main color opening yarn feeding orifice, a match color opening yarn feeding orifice and a stretch yarn feeding orifice according to vamp patterns and process requirements, loading written program into a vamp machine, and inputting parameters corresponding to the vamp patterns and process requirements;

(2) weaving U shape tube fabric;

one side of the U shape tube fabric being an outer vamp, the other side being an inner vamp, both the outer vamp and the inner vamp being of a tube shape, a turn in the middle of the U shape tube fabric being a shoe opening part where the inner vamp and the outer vamp intersect;

the vamp machine weaving in an order of a starting opening, an outer toe cap, an outer shoe body, an outer heel, an outer shoe opening to an inner shoe opening, an inner heel, an inner shoe body, an inner toe cap, during the course of weaving, achieving technical effects of local jacquard and local texturing at portions of the outer vamp;

(3) stitching an inner toe seam;

grasping the woven U shape tube fabric to a stitching device by an automatic robot arm, locating an inner toe opening at a needle position of the stitching device, performing aligned automatic stitching along the inner toe opening to form the inner toe seam;

(4) stitching the outer toe seam;

sucking the U shape tube fabric to an outlet opening through a suction pipe, taking the U shape tube fabric where the inner toe seam has already been stitched from the outlet opening, stitching the outer toe seam;

(5) forming a one-piece-vamp semifinished product;

overlapping the inner vamp and the outer vamp by extending the inner vamp into the tube of the outer vamp in the shoe opening part, forming a two-layer one-piece-vamp semifinished product; and

(6) performing reshaping, setting and shape fixing on the vamp;

putting the one-piece-vamp semifinished product on a shoe tree, using steam to perform scalding, making adjustment to the vamp and patterns for position alignment during the course of scalding, melting the hot melt silk to adhere the inner and outer vamps to each other as one piece, taking the shoe tree out after cooling, and forming the one-piece-vamp.

2. The one-piece-vamp manufacture method according to claim 1, wherein:

said vamp machine is equipped with 1 main color opening, the main color opening is equipped with 8 main color opening yarn feeding orifices, and the hot melt silk is fed by at least one of the main color opening yarn feeding orifices, said vamp machine is equipped with 6 match color openings, each match color opening is equipped with 3 match color opening yarn feeding orifices and 1 stretch yarn feeding orifice.

3. The one-piece-vamp manufacture method according to claim 2, wherein:

said 8 main color opening, yarn feeding orifices are used for inner yarn feeding, outer yarn feeding, inner hot melt silk, outer hot melt silk, inner heel yarn feeding and hot melt silk, outer heel yarn feeding and hot melt silk, starting opening yarn feeding, and scrap yarn feeding, respectively, and according to a main color of the inner outer vamp and the process requirements, 4-8 main color opening yarn feeding orifices are chosen for yarn feeding.

4. The one-piece-vamp manufacture method according to claim 1 wherein:

an outer shoe shaft and an inner shoe shaft are provided between said outer heel and outer shoe opening, and between the inner shoe opening and the inner heel, respectively, in said step (2), and when the U shape tube fabric is woven, said stretch yarn feeding orifice cooperates with the main color opening yarn feeding orifice, so as to allow the inner and outer shoe openings and the inner and outer shoe shafts to be textured and woven.

5. The one-piece-vamp manufacture method according to claim 1, wherein:

in said step (3), the U shape tube fabric is grasped and rotated to the stitching device muzzle bell by the automatic robot arm, said U shape tube fabric being located by a sewing needle disc and pushed straight by a top shaft, so that the inner toe seam is located at the sewing needle position of the stitching device.

6. The one-piece-vamp manufacture method according, to claim 1, wherein:

in said step (4), a seam disc machine is used to perform manual stitching on the outer toe seam, and a starting opening yarn and a scrap thread at the starting opening are subsequently manually removed.

7. The one-piece-vamp manufacture method according to claim 1, wherein:

in said step (6), 100°

C. to 120°

C. steam is used to perform scalding, and a transparent alignment plate is used to make fine manual adjustments to the vamp and patterns for position alignment during, the course of scalding.
