Appeal No. 2005-1635
Application No. 09/782,036
scattering powder, granules, or pellets of a thermoplastic
material onto a first substrate to form a first coating;
applying a second substrate over the first coating;
scattering powder, granules or pellets of a thermoplastic
material onto the second substrate, after said second substrate
has been applied over the first coating, to form a second
coating;
leading the second substrate between a belt of a low
pressure press and said first substrate;
applying heat to fuse the coatings between the belt and the
first substrate;
smoothing the fused coatings between a pair of nipping
rollers to provide a layer of desired thickness; and
cooling the layer.
8. A method as claimed in claim 1 including a step of
adjusting a gap between the nip rollers.
13. A method as claimed in claim 1 wherein the first
coating is of a saturation material to form, on heating, a
saturation layer.
32. A method as claimed in claim 1, wherein said step of
scattering powder, granules or pellets onto the second substrate
comprises scattering powder, granules or pellets of a
thermoplastic material onto the second substrate, after said
second substrate has been contacted with the first coating.
