Description

【Technical field】 [0001] The present invention relates to a shoe, more specifically to a lasted-in leather welt-turned shoe and its manufacturing method, and also to a special tool for manufacturing lasted-in-turned-in shoes. 【Background technique】 [0002] The current shoe-making process is in a stage of development with each passing day. The existing shoe-making process is divided into the following five types according to the shoe-making process: seam process, adhesive process, vulcanization process, injection (extrusion) plastic process, and molding process. The professional term of stitching technology in the shoe industry is called Goodyear method, and the shoes made by this method are called Goodyear shoes. Its characteristic is that it is stitched with "threads". During the production, the combination of the shoe surface and the sole is made of waxed ramie, nylon knots, etc., and the shoes are stitched manually or mechanically, and the last-style leather welt is turn...

Problems solved by technology

[0004] The disadvantages of this method are: many process steps; long production process time; when fixing the upper and the midsole, it is necessary to climb the front and sweep the toe, and the length of the toe captured when climbing the front is determined by the operator's technique and Controlled by experience, it is difficult to control the warping of the toe of the shoes, and the warping of the toe will be inconsistent; because the sock cover will be broken during climbing, it is impossible to make shoes with sock cover, and the toe cap of Gangbao or The exposed condition of the head reinforcement is unstable; the valgus is not flush with the outer edge of the midsole and the outsole, and it needs multiple trimming and grinding to make the edges smooth and beautiful, which wastes materials and labor; while the midsole is completely Made of genuine leather, the cost is high, and the shoes produced are very hard and heavy; and when climbing, due to the different materials of the leather, it is easy to have uneven patches, uneven or broken toe caps, etc.
