Application No. 09/782,036
first substrate (having thereon a coating of
thermoplastic granules or pellets) before that second
sheet is scattered with powder, granules or pellets of
a thermoplastic material. That is, although the end
product of claim 32 may appear similar to that in
Takeuchi, claim 32 sets forth a particular order in
which the sheet is assembled. And that order is not
taught or suggested by Takeuchi. [Footnote omitted.]
The appellants’ argument is not well taken.
As indicated supra, Takeuchi not only teaches forming a
laminated floor covering having a textile sheet coated on one or
both sides, but also exemplifies coating the bottom side of a
textile sheet, such as a glass fiber layer, with thermoplastic
powder by providing thermoplastic powder on a steel conveyor
belt and then placing the glass fiber layer (core layer) over
the powder to produce a laminated sheet. As also indicated
supra, Brinkmann teaches, inter alia, coating the top side of a
textile sheet by proving a textile sheet over a conveyor belt
and then placing thermoplastic powder on the textile sheet to
form a laminated sheet. Thus, one of ordinary skill in the art
interested in forming laminated floor coverings comprising
thermoplastic powder coating on both sides of a textile sheet as
discussed above would have been led to use the claimed
sequential application of thermoplastic powder, a textile sheet
and thermoplastic powder on a conveyor belt, motivated by a
