Liquid coating method and apparatus with a deformable metal roll

Abstract

Methods and apparatuses for applying liquid coatings are provided. A first roll (14), a second roll (16), and a nip (146) formed between the first and second rolls are provided. A coating liquid (22) is supplied to the nip. The coating liquid is smoothed, via the nip, into a substantially uniform layer (22a) of liquid coating which is transferred to a substrate (12). The second roll (16) includes a thin metal shell (40) and a resilient layer (30), the thin metal shell encases the resilient layer therebeneath, and the thin metal shell is capable of deflecting in unison with the resilient layer such that the thin metal shell is elastically deformable at the nip when in contact with the first roll (14).
