Before operating the machines used to build the boxes, the extraction system must be turned on. It collects wood shavings and sawdust to ensure longer machine life and a cleaner work environment.
The source of the sound cannot be located visually and fills the entire room, encapsulating the workshop with a low but omnipresent humming noise As the engine powers up, the volume follows a rising, spiral pattern until reaching its loudest point. This sound underlies and accompanies every stage of production.
Since 1949, the name Lessmann has been synonymous with traditional box-making craftsmanship, based in Nördlingen, Bavaria. The workshop is now in its third generation of family ownership under Werner Lessmann.
They manufacture wooden boxes for all types of beverages and gift packaging. The company is dedicated to producing beer and wine boxes, as well as custom-made products and designs from sustainable wood.
Most of their machines date back to the 1960s, with a few newer ones from the 1980s onwards . And that makes it all the more important to capture their sound.
The company’s main customers are beer, wine, and coffee distributors who require special packaging.
Here we hear how a six-pack carrier suitable for beer or similar types of bottles is made.
