(54) | Process and apparatus for coating sheet material |
(57) A process for coating sheet material (6) at high speed with a low viscosity low coat
weight coating comprising the steps of forming, on an endless transfer surface (1),
a fluid film of a coating mix to be applied to the sheet material whilst moving the
endless transfer surface (1) on a convex path through a coating station, and in the
second direction of movement of the transfer surface, and simultaneously passing the
sheet material (6) to be coated around an endless guide surface (7) at said coating
station, whilst maintaining the spacing between the transfer (1) and guide surfaces
(7) at a spacing substantially equivalent to the combined thickness of the sheet material
and the film of coating mix on the transfer surface (1). |
