Description

Three-dimensional upper manufacturing method

The present invention discloses a method for manufacturing a three-dimensional upper, and more particularly to a 3D three-dimensional manufacturing method having a patch on a shoe upper.

Existing sneakers (or sneakers) must have a patch on the upper for certain needs. For example, for aesthetic needs, a decorative patch is provided. For commercial and other manufacturers, there is a trademark patch. In order to provide a reflective patch for nighttime walking, there are also settings for the toe patch, the shoe patch, the sill patch, etc., in addition to the aesthetics and functional requirements.

In the above method for manufacturing the upper, the various patches are sewn on a flat substrate on a flat substrate, and the planar substrate on which the patch is sewn is molded on a hoe. The problem is:

1. Using a sewing machine to sew a flat patch on a flat substrate, it is impossible to sew a flat material into a three-dimensional shape that conforms to the shape of the hoe. Therefore, a strong shaping is required, and the shaping is generally performed using a tong. Helping the machine, in the shaping, strong pulling force may damage the material, the material is also prone to wrinkles and deformation, resulting in different quality from the original design, of course, the quality is not high.

2. Sewing the patch on the substrate requires a large number of skilled workers. Unskilled workers are in a state of lack of work, and skilled workers are less likely to be cultivated, causing difficulties in mass production.

3, the shoes with large arcs need to be warped first, the technical difficulty is very high, so it is difficult to stick, the quality is difficult to control, which is one of the reasons for the high defect rate.

4. After shaping, the upper will return to the original plane state due to the memory characteristics of the material, affecting the process of forming and the bottom part of the back, and the finished shoes can not reach the expected beautiful three-dimensional state, resulting in poor quality. as a result of.

5. The whole shoe has a long process time, low efficiency and high defect rate.

In addition, there is Taiwan Patent Publication No. 201230976, which cannot solve the above problems completely. Although there are also manufacturers who provide integrally formed substrates and reinforcing materials for reducing the labor demand, and the manufacturing method thereof, such as PCT/JP2013/051464 (corresponding application TW201434408A), the sole of the shoe has only one material. The inability to provide different and diverse uppers also does not adequately address these issues.

The present invention solves the above problems by providing a method for manufacturing a three-dimensional upper, which comprises the following steps: A. arranging a partial sock-like substrate forming a vamp to the above-mentioned foot type having a core of a foot portion Department B; pre-set the position of the vamp on the substrate; C, glue the position of the vamp on the substrate; D, attach the vene to the position of the vamped vene E, press the veneer patch to the substrate.

The above method for manufacturing a three-dimensional upper includes a step of pressing together an outer mold corresponding to the core.

In the above method for producing a three-dimensional upper, the outer mold is heated to perform thermocompression bonding.

In the above method for manufacturing a three-dimensional upper, the glue is a hot melt adhesive.

In the above method for manufacturing a three-dimensional upper, in which the position of the upper patch is digitized, the hot-melt adhesive is sprayed on the upper patch position by numerical control.

In the above method for producing a three-dimensional upper, the substrate is a stretchable or flexible cloth.

In the above method for producing a three-dimensional upper, the cloth is woven, dermis or synthetic leather.

The above method for manufacturing a three-dimensional upper, wherein the upper patch is a woven fabric, a non-woven fabric, a genuine leather, a synthetic leather, a plastic material, a rubber material or a reflective material.

In the method of the present invention, the vamp patch is attached to a 3D solid foot core, that is, the sock-like substrate is made of a stretchable or flexible material, which is substantially completely conformable to the taro. The shape is completely affixed, and the vamp patch is attached to the spliced sock-like substrate, which fully conforms to the curvature of the hoe, and the bonded substrate and the vene sheet are not deformed. It also conforms to the expected shape. Therefore, the quality is easy to reach the standard, and the defect rate is also reduced, which solves the problems of strong shaping, material memory characteristics and poor adhesion of the prior art. In addition, there are few parts to be sewn in the process of the present invention, which can avoid relying on the large demand of skilled workers, and the glue can be automatically used. The numerical control and the fast coating speed not only shorten the entire process time but also improve the efficiency, and can solve the problems of the prior art mentioned above.
