Embodiment 1

[0040] Get a large piece of cowhide as the main skin 20, the thickness of the main skin 20 is 2mm, take a paper grid as a reference, and the paper grid is a rectangle. Referring to the paper grid, process a strip-shaped slot with a depth of 1mm on the surface of the main leather 20; trim the edge of the matching leather 30 so that the matching leather 30 can just fit into the above slot, and the matching leather 30 The thickness is 0.8mm; trim the long strip of hot melt adhesive that can be placed in the slot. The thickness of the hot melt adhesive is 0.4mm. When the hot melt adhesive is not unpacked, it is usually wrapped temporarily with adhesive paper.

[0041] Finish the edge of the slot, use an oblique knife to cut across the side of the slot, and process an inclined cut. The angle of the cut can be 50-80°.

[0042] Preheat the hot melt adhesive with an iron at 50°C for 10 seconds, and put the hot melt adhesive into the slot. Lay four strips of smooth cardboard around th...

Embodiment 2

[0046] Get a large piece of cowhide as the main skin 20, the thickness of the main skin 20 is 3mm, get some paper grids as reference objects, and the paper grids have broken lines, arcs and rectangles. With reference to each paper grid, slots with a depth of 2mm are machined at different positions on the surface of the main leather 20 with a shovel knife. The shapes of the slots are respectively broken lines, arcs and rectangles. figure 2 The slot in the upper right corner of the front of the leather goods (with leather 30) is an isolated island, and the slot in the lower left corner of the front of the leather goods (with leather 30) is in contact with each other. Trim the edges of several matching skins 30, so that each matching skin 30 can be embedded in the corresponding slot, and the thickness of all matching skins 30 is 1.7mm. Trim several strips of hot melt adhesive that can be put into the slot. The thickness of the hot melt adhesive is 0.5mm. When the hot melt adhesi...

Abstract

The invention relates to a leather splicing method and a leather product. The method is characterized in that a hot melt adhesive and a matching leather are sequentially placed into a groove positionof a main leather, the main leather and the hot melt adhesive are fed into a cloth ironing machine, the hot melt adhesive and the main leather are preliminarily connected and shaped, then the main leather, the hot melt adhesive and the matching leather are fed into the cloth ironing machine, and the matching leather and the main leather are preliminarily connected and shaped, although the operation process is lengthened, the connecting quality is easy to guarantee, the waste of high-grade leftover materials can be avoided by reducing accidents, and the cost is more economical and practical. According to the method, the scrap high-grade leftover materials are fully utilized, waste is reduced, even waste utilization is achieved, the production cost of an enterprise is greatly reduced, and the purposes of greenness and energy conservation are achieved; and a brand new splicing method is adopted, the quality of splicing between the main leather and the matching leather is good, connectionis firm, layer separating is avoided, gaps are avoided, and simplicity, attractiveness and good overall consistency are achieved. The method is applied to the field of leather production and leather product manufacturing.

Description

technical field [0001] The invention relates to a production process of leather materials, in particular to a method for seamless splicing of leather materials and leather goods using the above-mentioned leather materials. Background technique [0002] As a necessity of life, leather goods are used in business, travel, daily life and other occasions. For leather goods using high-grade leather materials, they are expensive first, and they must satisfy both practicality and uniqueness. Based on the above status quo, leather goods factories will cut out ingenious leather materials when producing leather goods, and then sew them together. Since the small pieces of leather cut out are irregular, irregular unusable leftovers are likely to remain in the whole large piece of leather. How to utilize the above fragmentary and high-grade leftover materials has become a stumbling block to reduce the cost of enterprises and take the road of green production. [0003] Considering that ...
