After that, as shown in FIG. 7, the cloth is evenly spread on the back surface of the leather fabric 1 to which the adhesive 1a is sprayed, and then the cloth is made to not cry, and the pressure is applied to the back surface of the leather fabric 1. (S20)

After the leather fabric 1 and the cloth is integrally bonded as described above, as shown in FIG. 8, a plurality of cut leather fabrics 1 are transported to a place where a leather case is made by cutting a plurality of pieces according to the size of the product. (S30) One leather fabric 1 of the cut leather fabric 1 is seated on the lower mold 20 coupled to the base 7 of the molding machine 9 by the lower plate 10 to the leather case of Complete the molding preparation. (S40)

When the molding preparation of the leather case is completed, as shown in FIG. 9, the upper cylinder 60 is lowered by operating the main cylinder 6 configured at the upper side of the molding machine 9. Then, as shown in FIG. 10, the upper mold 80 coupled to the upper plate 60 is lowered to compress the back surface of the leather fabric 1 seated on the lower mold 20, wherein the lower Since the mold 20 receives heat by the hot plate 8, the leather fabric 1 is thermocompressed by the upper and lower molds 80 and 20.

Then, when the thermal pressing of the leather fabric (1) is made, the adhesive (1a) bonded between the leather fabric (1) and the cloth (2) is hardened so that the leather fabric (1) is firmly molded without bleeding. (S51)

After forming the thermocompression molding by the upper and lower molds 80 and 20 as described above, the side cylinder 90 is operated as shown in FIG. Then, the side cylinders 90 respectively configured on both sides move the first and second sliders 40 and 50 in the direction in which the leather fabric 1 is seated, respectively, to form side surfaces of the leather fabric 1. The leather fabric 1 is pushed by the first and second side molds 41 and 51 formed in the first and second sliders 40 and 50, respectively, and is naturally folded according to the shape of the upper mold 80.

Therefore, the side of the leather fabric (1) is firmly thermocompression molded according to the shape of the upper mold (80), the first and second side molds (41, 51), (S52) through the same process When the manufacture of the leather case 150 is completed, after returning the side cylinder 90 and the main cylinder 6 to the initial state, as shown in Figure 12, the production of the finished leather case 150 is viewed as Production of the leather case 150 of the invention can be completed.
