      About us

      The company Lamit has been a supplier of automated adhesive application systems and line design concepts for producing raw mattresses primarily for the mattress manufacturing industry since 1989. Lamit is a pioneer in the design and production of automated modular systems and line concepts for all common bonding processes in the mattress and foam processing industry.

      In addition to specialized Lamit application systems for processing polyurethane adhesives for various foam products and this is just one example. Bäumer's Lamit bonding technology offers two different adhesive application processes for the mattress industry. Depending on the application and, in particular, on the mattress type, either water-based dispersion adhesives or hot-melt adhesives are used.

      Albrecht Bäumer GmbH & Co. KG incorporated Lamit’s product range in 2015.
