Erretre's Black Line represents the latest generation of milling drums

摘要

Whether it is a hot or cold environment, in the milling operation, it is essential that the temperature and humidity are carefully controlled to all but guarantee a high-quality result. Cold Milling is particularly suitable for leathers that are sensitive to temperature and humidity such as non-chrome tanned leathers and all smooth leathers in general. Erretre Chief Operating Officer, Antonio Galiotto, explained that there is more to the name than just temperature. He explained that what Erretre aims to offer tanners with Cold Milling is the ability to make better, flatter, softer leather. "It's not simply about keeping the temperature low," Mr Galiotto said. "This system has two independent circuits, which gives it the ability to absorb heat that is generated by friction during milling. It's this that gives flatter, softer leather." The Black Line version is a process patented by Erretre and has resulted in a reported 15% increase in milling efficiency over its standard milling drum process, which reaches up to 30% in the Cold Milling version. The dust abatement capacity has also seen a 20% improvement. Speaking to World Leather, Mr Galiotto said, "We have several patents, relating to different points of the drum operation. Many have already been approved and extended abroad, others are in the process of being approved."
