Fabricating method of special last fixing shoe

Abstract

The invention discloses a fabricating method of a special last fixing shoe, which comprises the following steps: (1) lathing a sized upper with an internal middle base sheet with an iron core fixed at the bottom; (2) driving a toe last into the upper, lathing an outer welt at the edge of the outer side of the bottom of the semi-finished shoe made by the step 1; (3), placing a filling layer at thebottom of the internal middle base sheet and sticking a thin bottom; (4), lathing the thin bottom with the outer welt together; (5), sticking a big bottom; and (6), edging and arranging. The invention leads the shoe-making process to be more convenient without three procedures of lasting, driving nails and edging, shortens the production time, and lowers the input cost of a device and the production labor cost. The invention omits the lasting procedure, accordingly saves the edge leather preserved at the upper because of the lasting, and lowers the material cost. The defects of shoe cap breaking, unsmooth upper, easy crinkling and the like easily caused by the lasting can be avoided, and the quality of the finished shoe can be further improved.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of lasted Goodyear shoes. 【Background technique】 [0002] As early as more than 300 years ago, the shoemaking method of sewing the outer edge came out in England. The original method was to sew the three parts of the outer edge, upper and inner midsole together by hand, and then thread or glue the outer edge and the outsole together to form a pair of shoes. It was not until 1872 that the British "Charles Goodyear" designed the world's first outer edge sewing machine, and the shoemaking method of outer edge sewing was widely used. Therefore, to commemorate this great invention, the footwear made of other welts will be collectively referred to as Goodyear (GOODYEAR) shoes in the future. When making, the upper surface of the shoe and the sole are combined by using waxed ramie, nylon knots, etc. to make shoes by manual or mechanical sewing (also called car synthesis), such as figure 1 , 2 As shown, the ...

Problems solved by technology

When making, the upper surface of the shoe and the sole are combined by using waxed ramie, nylon knots, etc. to make shoes by manual or mechanical sewing (also called car synthesis), such as figure 1 , 2 As shown, the existing inner midsole 200 includes a bottom layer 201, and an inner edge strip 202 is arranged on the bottom layer 201. In the prior art, the inner edge strip 202 is combined with the bottom layer 201, and then placed under the last , use the hot melt glue sprayed by the pincer machine to combine the upper with the edge of the inner midsole inner strip 202 placed under the last (referred to as the pincer side), use a wire machine to put steel wire nails, and use a beveling machine to cut This kind of shoemaking method has many procedures; the production process takes a long time; when making shoes, it is easy to cause the toe cap to be broken due to the clamp upper, and the upper is not smooth. It is easy to wrinkle and other defects; the inner and midsole are made of hard plastic material, which is hard and heavy; this method needs to leave more leather at the bottom of the upper when making the upper, so that the upper can be connected with the inner by the upper. It is more convenient when the edge of the midsole is combined, so that the leather is wasted
