Leather shoe sole attaching and edge sealing method

Abstract

The invention discloses a leather shoe sole attaching and edge sealing method, which belongs to the technical field of leather shoe sole attaching and edge sealing, and particularly comprises the following steps of: polishing and flattening a shoe sole of a leather shoe and a shoe heel to be attached, and uniformly brushing treatment water on the shoe sole and the shoe heel; after the treated water is air-dried, brushing resin glue, and uniformly smearing the shoe sole and the shoe heel; adjusting the temperature of the oven to 50 DEG C, when the set temperature is reached, putting the shoes and the shoe heels into the oven, enabling the surfaces brushed with the glue to face upwards, taking output the shoes and the shoe heels after being baked for 2 minutes, pressing the shoe heels on theshoe soles, extruding middle bubbles, pressing the shoe soles for 10 seconds, and bonding the shoe soles and the shoe heels completely; trimming redundant shoe soles, firmly pasting the shoes, usingscissors or a tailoring tool to trim redundant shoe heels along the shoe edges; and polishing the trimmed shoe edges to be smooth, so that the shoe heels and the shoe soles are more attached, the filling property of the nano quick-drying glue is utilized to fill the thin and undetectable gap between the shoe heels and the shoe soles, the contact between the south light resin glue and water and dust is isolated, the glue failure probability is reduced, and the service life of the shoe heel is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of leather shoe palm edge sealing, in particular to a method for leather shoe palm edge sealing. Background technique [0002] In the field of luxury leather care, it has always been an industry problem that the edge of the shoe is easily degummed and warped after the sole is attached to the sole. This technology is specially developed to solve this kind of problem; The edges are embossed. In the prior art, the general leather products are processed and shaped through the production line, and it is inevitable that there will be defective products with burrs on the outer edge or unformed embossing. If the defective products are directly discarded, raw materials will be wasted; and for high-end leather products , It needs to be made by hand, and the edge embossing is also a problem. The traditional way of edge sealing is generally dry naturally. You can't use other means to make the edge dry quickly, which wi...
