Latest Patents
Grasten's latest patents include a coater designed for selectively coating a running web either on one side or both sides. In his first patent, he describes a device for alternatively one- or double-sided coating of a running paper web. This device features a smoothing nip that includes a first roll and a counter member. The design incorporates means for leading the web from below upwards into the smoothing nip. Before reaching the smoothing nip, a coating substance applicator applies the coating substance in a non-pressurized manner, allowing it to adhere to the web as it travels upwards. The web moves linearly from the applicator to the smoothing nip, ensuring a smooth application process.
In his second patent, Grasten presents an appliance for double-sided coating of a moving web. This device utilizes two coating substance applicators and a smoothing nip, which comprises a back-up roll on one side of the web and an adjustable leveling blade on the other side. The coating substance is applied directly to the web on the side facing the leveling blade and on the surface of the back-up roll on the opposite side. The design ensures that both the smoothing nip and the applicators are located within a 30-degree sector of the back-up roll, preferably within a 20-degree sector, optimizing the coating process.
