The image demonstrates the process whereby leather is produced.
Generally speaking, it is evident that the process entails six stages, predominantly transforming animal skin into leather and then coloring it with the aid of various sophisticated machines. The process itself is almost fully automated, relying on limited human interference.
The initial stages of the process involve delivery and sorting. The process commences with animal skins being delivered from farms to be sorted into large and small sizes. Having been sorted, the skins are then trimmed and salted by humans in the next stages. Following this, the salted skins must be cured for about 30 days and put in a sink that is responsible for soaking them for up to 24 hours.
In the following stage, humans remove the hair from the ready skins by using knives. After the removal, it is sent to another machine that mechanically pickles them by adding acid and salt. The tanning stage features the usage of chemicals, which lasts for 2 days so that they can finally be colored and polished in a large round vat. In the next and final stage—one of the parts with human intervention—the ready leather is then dried by a drier and ironed by a staff member, respectively.
