Bonardi Converting s.r.l.
Bielloni was founded in 1919 by Guglielmo Bielloni, the grandfather of the current company president, Dr. Alessandro Castello.
The first company, "Officina Meccanica Figli di G. Biagioni", was established in 1950. It was in those years that the first knife-edge paper bag making machine was built, entirely from hand made parts.
