Germany Lacom has recently introduced multi-function coating complex machine. The machine is made up of multi roll hot-melt compound machine and engraving roller coating complex machine. It can be applied to hot melt adhesive and solidified active hot-melt adhesive coating. The coating method is a little coating and two kinds of coating, and can be heated by heat conducting oil. The multifunctional coating compound machine is designed with modular design to facilitate the conversion of processing varieties. When using the engraving roller coating, the hot melt adhesive coating amount is 3 grams / square meter to 40 grams / square meter. When the multi roll coating is applied, there are 5 g / m2 to 60 g / m2, 5 g / m2 to 150 g / m2, 150 g / m2 to 800 g / M2, etc. the three grades of hot melt adhesive coating can be selected, and its production speed is 3 M / min to 60 m / min.
