Holiday season is the time of baking. Dough is mixed, kneaded, rolled out and then cut out or shaped. Most of these traditional preparation steps can also be found in industrial manufacturing but not only in bakeries - Mixers, kneaders, mills and cutters are used in production of rubber articles.
The production of rubber articles started mid-19th century with similar processes, after Charles Goodyear invented the vulcanization of natural rubber in 1839. Before, the application of rubber was focused on impregnation of textiles, shoes and hoses. Vulcanization was the crosslinking of gums to rubber, an elastomeric material, able to recover its shape after deformation on its own.
