Embodiment 1

[0008] Example 1: The front panel material goes through the following processes: draw the curved stilt line → brush water → paste the reinforcing cloth → curved stilts → press the stilts: press the semi-finished front panel after the curved stilts with 15 kg for 20 minutes → put in the freezer Cool at -2°C for 1 hour → glue the half panel → cut the material line → clear the edge → number and pair → finished the front part.

Embodiment 2

[0009] Example 2: The front panel material goes through the following processes: draw the curved line → brush water → paste the reinforcing cloth → curved stilts → press the stilts: press the semi-finished front panel after the curved stilts with a force of 18 kg for 30 minutes → put it in the refrigerator Cool at -3°C for 1.5 hours → glue the half panel → cut the material line → clear the edge → number and pair → finished front parts.

Embodiment 3

[0010] Example 3: The front panel material goes through the following steps: draw the curved stilt line → brush water → stick the reinforcing cloth → curved stilts → press the stilts: press the semi-finished front panel after the curved stilts with 20 kg for 40 minutes → put it in the freezer Cool at -4°C for 2 hours → glue the half panel → cut the material line → clean the edge → number and match pairs → finished front parts.

Abstract

The invention discloses a warp-pressing and cutting method for avoiding boot vamp deformation. The method comprises the following steps of: marking a warp line, swabbing, adhering reinforcing cloth, warping, pressing the warp, performing cool setting of the warp, pasting a semi-panel, marking a cutting line, edging, and obtaining finished products. By adopting the technical scheme, the invention has the advantages that: the warped semi-finished products are subjected to warp pressing and cool setting of the warp, the vamp materials are subjected to setting twice, and the pasted semi-panel can make a vamp switch and the boot tree radian consistent completely; therefore, the problems that the height and length of inner and outer ankles of the warped vamp are easily changed and the warped vamp deforms and does not accord with a template due to different leather flexibilities are solved. The method is easy and convenient to operate, and the phenomenon of tilted vamp rarely occurs, so that the appearance quality of the finished boot is greatly improved, and the defective rate is reduced to 0.23 percent. Therefore, the manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to a manufacturing process of leather shoe leather or boots, in particular to a treatment method for solving the deformation of the front upper of leather shoes or leather boots. Background technique [0002] Most of Liren's shoes and boots have a high-waisted structure, and the front parts must be curved in the finished product to conform to the standard last shape. However, due to the different stretchability of the leather, the height and length of the inner and outer ankles of the front are easy to change after the stilts, and the deformation of the stilts does not conform to the model. In the production of the finished product, there will be a phenomenon of skewing of the upper material, which will cause defects in the appearance of the finished shoe, and the defective rate is 2.98%. Contents of the invention [0003] The object of the present invention is to provide a method for solving the deformation of the front upper ...
