By the will of Quintino Broglia Marzé, who had already owned the Lanificio Broglia, operating in Biella, in the 1950s. In 1963, Quintino Broglia Marzé purchased the Lanificio Sella in Campore and transformed the two factories (Lanificio Sella and Lanificio Broglia) into the Lanificio Campore. Today, Lanificio Campore is managed by Quintino's son, Diego, with his daughter Cristina. In 2000, Lanificio Campore acquired the Torello Viera wool mill. The original factory structure dates back to 1830, founded by the Sella brothers. In 1831, brothers Pietro, Gio Battista, and Vincenzo Sella founded a factory in Campore called Lanificio Macchina Nuova. This name derives from the purchase of a large, new, and modern loom manufactured in Belgium. Tradition holds that transporting this large loom required a large cart pulled by six horses. Hence the name: Lanificio Macchina Nuova. In 1895, it was registered as Lanificio Successori Sella until early 1924. Then, on October 14, 1924, it became Lanificio Sella. Finally, in 1963, it became Lanificio Campore.

From the beginning, Lanificio Sella (Campore) specialized in the production of heavy woolen coat fabrics. It soon became an official supplier to the Italian army and received large orders during the First World War (1915-1918).
Subsequently, they continued to produce woolen fabrics for men and women.
Since the end of the Second World War, the factory has continued to create and produce fabrics for tailors, haute couture, designers, and apparel to the present day.
