The Hotmelt Coating Machine (Figure 1) is used for coating flat substrates with hotmelt. Therefore the substrate to be coated is passed between pressure and application rollers, which are driven in opposite directions at a desired speed, as depicted in figure 2. The upper part of the application roll immerses into the lower opening of the melting tank and then transfers the heated and therefore liquid thermoplastic polymer material onto the substrate.
