The BÜHNEN melting system for bags is an easy to maintain, adhesivefriendly melting device that combines the advantages of a drum melter with a tank system. The melting stock is converted straight from the bag, thereby minimising contamination of the device. The bag melter works without production downtime. For „melting on demand“, the melting stock is melted in two stages. The adhesive cartridge is compressed through a melting grid by means of a piston; the hot melt adhesive then flows into a reservoir. When the reservoir is full, the melting grid is automatically shut down. This creates constant viscosity in the reservoir and ensures continued production quality.
