Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] A lean manufacturing method for Goodyear stitched shoes: First, prepare the required upper 1, welt 2, midsole 3, filling layer 4 and outsole 5, such as figure 1 As shown; then, use a special sewing machine 7 to directly sew the shaped upper 1 with the welt 2 and the midsole 3 into a whole (the traditional crafts are: first clamp, pull nails, sew the inner welt, and cut the upper foot , Sanding, bottom bonding), such as figure 2 As shown; secondly, put the...

Abstract

The invention discloses a lean making method for Goodyear seam shoes. The method comprises the steps that all components of a shoe body are divided into standard components, namely a vamp, a welt, an insole, a packing layer and an outsole; the vamp, the welt and the insole are sewn into a whole; the packing layer and the outsole are mounted, and then a Goodyear seam shoe is made through a heat setting process and a cold setting process. According to the lean making method, five processes including upper clamping, nail pulling, upper foot cutting, grinding and upper bottom bonding in the traditional art are omitted, production cost is lowered, investment of personnel is reduced, the making process is simplified, and more consumers can put on the novel Goodyear seam shoes which are firm and durable; besides, a whole plastic piece is used as the packing layer of the insole, and the insole is more comfortable than a traditional insole filled with cork; moreover, bonding through mucilage glue is not needed, so that time and labor are saved, and environmental friendliness is achieved.

Description

Technical field [0001] The invention relates to shoe sewing technology, in particular to a lean manufacturing method for Goodyear stitched shoes. Background technique [0002] The Goodyear welt process is a unique manufacturing process for the world's top shoes, with a history of nearly 200 years. The traditional Goodyear method is to manually stitch the upper, midsole, and welt together, and then attach the outsole. Traditional components are complex and diverse, making industrial production difficult. The filling layer of the sole is filled with cork, which is time-consuming and labor-intensive, and the glue used for bonding between the corks is not environmentally friendly. In addition, the process also requires more than 360 processes such as last making, cutting, sewing, tongs, nailing, sewing inner welts, cutting feet, sewing soles, matching heels, and modifying. Existing Goodyear shoes are loved by consumers because of their sturdiness and durability. However, the produ...
