Abstract
Methods and apparatuses for applying coatings on a moving web are provided. A slot die including a concave die lip coating surface and a back-up roll engage with each other. The back-up roll has a deformable inner layer with a surface thereof covered by a deformable outer layer. The slot die and the flexible web at a contacting area are impressed into the back-up roll with an engagement depth D, which enables formation of a coating having a substantially uniform thickness.
