Shoe upper and necking shaping method of shoe upper

Abstract

The invention provides a shoe upper and a necking shaping method of the shoe upper, and belongs to the technical field of shoes. The problem that technical requirement for workers is high in an existing upper seizing working procedure is solved. The shoe upper comprises a shoe surface and an upper pulling wire, wherein two ends of the upper pulling wire are arranged in a crossed manner; and the two ends of the upper pulling wire pass through wire pulling rings at two ends of a rear bottom edge respectively. The necking shaping method of the shoe upper comprises the steps of firstly setting the shoe upper on a shoe tree and then pulling the two ends of the upper pulling wire until the tensile force of the upper pulling wire reaches a designed tensile force value; in the process, a bottom opening of the shoe upper is gradually decreased, the upper pulling wire and the upper pulling rings are tightened, and the ends of the upper pulling wire are arranged in the crossed manner so that the spacing between the inner side bottom edge of a waistline and the outer side bottom edge of the waistline is also synchronously decreased; and therefore, in the upper seizing working procedure of the shoe upper, the shoe upper at two waists can be really tensioned as long as the upper pulling wire is pulled to a required tensile force value, and the tension degree is moderate and average. The upper seizing working procedure omits the step of middle upper wire wearing and tying, and upper seizing can be completed just by pulling the upper pulling wire, namely shaping of the waistline is completed while the upper pulling wire is pulled.

Description

technical field [0001] The invention belongs to the technical field of shoes, in particular to a shoe upper. [0002] The invention belongs to the technical field of shoes, and relates to a shoe upper, in particular to a shoe upper necking and shaping method. Background technique [0003] In the shoe-making process, the gripping upper (also known as the clamping upper) is a process that best reflects the workmanship of the shoe. When clamping the front upper, it is necessary to ensure that the upper and the last are aligned; when clamping the middle upper, the uppers of the two waists must be really tightened, and the tension must be moderate and even; when clamping the rear upper, it is necessary to ensure that the heel height meets the standard. [0004] Most of the traditional shoe-making processes are produced by hand, especially the upper-grabbing process; image 3 As shown, in order to ensure that the uppers of the two waists can be really tightened, it is necessary t...

Problems solved by technology

[0004] Most of the traditional shoe-making processes are produced by hand, especially the upper-grabbing process; image 3 As shown, in order to ensure that the uppers of the two waists can be really tightened, it is necessary to wear and tie the mid-top line 2 on the two-waist uppers before pulling the grip line 1, and the length of the mid-top line directly determines the tension; High requirements, high labor intensity, difficult to control the tension, etc.
