The Clockwork of Packaging: Gaetano Barbieri and ACMA in Bologna, 1924

During the early 1920s, the burgeoning confectionery and consumer goods industries faced an acute bottleneck: wrapping individual candies, lozenges, and soaps required tedious manual labor. Gaetano Barbieri (1885–1959), a visionary mechanical designer trained in the demanding metallurgical traditions of northern Italy, conceived a mechanism governed by cams, gears, and synchronized grippers that could fold parchment and tin foil at unprecedented velocities.

His first breakthrough machine—capable of double-twist wrapping hundreds of candies per minute—stunned confectionery manufacturers across Europe. Barbieri’s workshop soon expanded into a full-scale industrial plant on Via Fioravanti and later Via Agucchi. ACMA became a true university of precision mechanics: dozens of young apprentices and draftsmen trained under Barbieri’s rigorous standards would later branch out to establish their own packaging machinery enterprises, weaving the dense industrial fabric that characterizes Bologna today.

ACMA represents that rare breed of interwar enterprise that not only survived the transitions of the 20th century but evolved into a pillar of modern international technology as part of the Coesia Group. The historic facilities along Via Agucchi stand as monuments to industrial engineering, where the tactile legacy of cast-iron lathe work has transitioned seamlessly into robotics, digital vision systems, and sustainable packaging solutions.

Bologna’s Museo del Patrimonio Industriale (Fornace Galotti) meticulously preserves original ACMA mechanical drawings, patent registers, and historical demonstration units, illustrating how Barbieri’s 1924 prototypes laid the foundations for the automated world we interact with daily.
