Problems solved by technology

However, this conventional method has difficulty in selectively attaching only specific leather pieces to the sponge roll
Additionally, the molten surface of the sponge sticks to the rollers, which pressurize and attach the sponge and leather sheet, thereby preventing continuous production

Abstract

The present invention relates to a method for laminating leather, comprising the steps as follows: separated papers are distributed on a horizontal workbench along a longitudinal direction; a plurality of leather sheets spaced to each other are fed to a position between two first rollers which are rotatable and matched with each other in order, wherein back sides of the leather sheets are upwards; a sponge is fed to the position between the two first rollers, a surface of the sponge is heated and fused by a heating device; while the fed sponge and leather sheets are pressed through the first rollers, the fused surface of the sponge is adhered to the back side of the leather sheet, so as to form a sponge-leather-separating paper composition; the sponge-leather-separating paper composition is cut into a predetermined size; the separating papers are removed, then the completed product is prepared for use.

Description

technical field [0001] The invention relates to a leather sheet lamination method and a leather seat made by the leather sheet lamination method. Background technique [0002] In general, there are different types of leather lamination methods, which are hot melt process and flame lamination process. In the hot-melt process, a sponge coated with a hot-melt adhesive and dried is attached to a leather piece under pressure in a heated oven. The process itself requires pressurization at 140 to 180°C for 20 to 30 seconds, under which conditions the leather loses its moisture, thereby degrading its quality. Therefore, the hot melt process is very limited in use. Furthermore, its complexity leads to lower productivity and higher costs. [0003] In the flame lamination process, the surface of the sponge is fused to become tacky so that the leather piece can be attached to the sponge. However, this conventional method has difficulty in selectively attaching only specific leather ...
