The diagram illustrates the process by which leather goods are manufactured, starting from raw animal skin through to the final products.
Overall, the manufacturing process is a multi-stage, linear sequence which begins with the preparation and treatment of the raw hides in one factory and culminates in the production of finished items in a separate facility.
In terms of the initial stages, the process commences when animal skins are first dried. Subsequently, they are transported to a factory for a cleaning procedure, which involves washing them in a solution of water and lime, followed by soaking them in lime again. Then, the treated skins are flattened by a large rolling machine.
Regarding the finishing stages, the flattened material undergoes a tanning process by being soaked in a mixture of water and vegetable matter. Following this, the leather is polished to create a smooth surface. Finally, the finished leather is transported to a second factory, where it is used as a raw material to manufacture consumer goods, such as shoes, handbags, and balls.
