Appeal 2006-1543
Application 10/239,769
INTRODUCTION
The claims are directed to a method and apparatus for making a web
of glazed paper or board. The process involves treating a base web with a
high-solids content treatment agent. This is done, according to the claims,
by applying the treatment agent to a heated belt of a belt dryer. When the
treated belt surface contacts the web, the treatment agent is transferred from
the heated belt to the web. Claim 15 is illustrative of the subject matter on
appeal:
15. A method for manufacturing a web of glazed paper or board with
a surface thereof treated with a treatment agent, comprising:
producing a base web;
applying a treatment agent to a surface of a heated belt, the treatment
agent having a solids content of not less than 80%; and
drying the base web in a belt dryer comprising the heated belt, the
surface of the heated belt to which the treatment agent is applied running
against a surface of the base web to which the treatment agent is to be
applied, wherein the treatment agent is transferred from the heated belt and
applied to the web by the heated belt to adhere to and coat the web.
