Coating Systems with Immanent Precision, 1999 Polymers, Laminations & Coatings Conference Proceedings
Gerd Kupfer--Most of the techniques used in the coating stations of coating and laminating machines originally come out of the printing technique. They, therefore, contain as well the disadvantages of the relevant printing method.
It is well known, the original flexo-printing stations alter the inking with an alteration of the speed, which is nothing other than an alteration of the coat weight. The alteration of the coat weight is created by an increase, or a decrease of the surface speed of the metering and the application roll, which leads to hydraulic pressures in the nip...
