Rubi Industria de Cremalleras is one of the oldest companies engaged in the manufacture of zippers.

[1][2][3] Cremalleras Rubi was founded in 1926 in the town of Rubí, Barcelona, which still maintains its headquarters and single plant.

In the 1930s, the British company Imperial Metallurgic Industries (IMI) bought the company and, having no experience in the market of the zippers, partnered with one of the European leaders in the industry, the German manufacturer Opti.

The Spanish subsidiary defaulted in 1981 and, four years later, bought their 256 employees making it a labor corporation (SAL).

The company, which in 1996 regained name Rubi Industria de Cremalleras, is already a conventional corporation, but “in spirit” remains in the hands of its workers.
