Sigma: Roller Buffing Machine

Sigma is our new roller buffing machine, ideal for automotive and upholstery leathers, designed to raise the quality level of the industry and meet the most advanced requirements.

The name Sigma, inspired by the mathematical symbol of the summation (Σ), reflects the idea of combining all the innovations and improvements resulting from our long experience in buffing in a single machine.

This approach has allowed us to create a machine that not only incorporates past advances, but also introduces advanced technological solutions to further optimise performance.

Sectors

In designing Sigma, we took a comprehensive view, rethinking every aspect of the machinery to overcome the limitations of traditional models. The result is a completely revamped framework capable of delivering superior performance, enhanced operational safety, simplified maintenance and optimized interactivity, ensuring a state-of-the-art user experience.

Think Green

Aware of its responsibilities, Bergi joined the “Supplier of Sustainable Technologies” project promoted by Assomac in 2017, with the aim of contributing to deepening the key issues related to the intelligent and conscious management of energy, water, and natural resources, with the perspective of qualifying the manufacturing industry’s production process as sustainable.

The focal point of the project is the “Green Label,” a voluntary declaration certifying the energy and environmental performance of machines, calculated based on internationally recognized parameters such as the CFP (Carbon Footprint, the amount of equivalent carbon dioxide emissions) measured using the shared and standardized Life Cycle Assessment (LCA) calculation methodology.
