Application No. 09/782,036
and/or Bradshaw, to form a laminated floor covering by using a
conveyor belt to coat both sides of a textile sheet with
thermoplastic particles as required by the claims on appeal.
On this record, we answer this question in the affirmative.
As indicated supra, Brinkmann, using its conveyor belt
arrangement, produces a single-layer floor covering with
scattered thermoplastic power on a conveyor belt or a laminated
floor covering with thermoplastic powder on a textile sheet.
Although Brinkmann does not expressly teaches a laminated floor
covering having both sides of the textile sheet coated with
thermoplastic power, i.e., thermoplastic powder on and below the
textile sheet on a conveyor belt, we find that Takeuchi teaches
that laminated floor coverings can be produced by applying
thermoplastic powder on one side of a textile sheet or both
sides of a textile sheet. See Takeuchi, Figures 1 and 2,
together column 7, lines 1-15, and column 10, lines 55-68 and
column 3, lines 50-68. We find that Takeuchi teaches that
thermoplastic powder can be coated onto a textile sheet via,
inter alia, a conveyor belt method. See Examples 11, 12 and 13
at column 10, line 55 to column 11, line 11. We find that
Takeuchi, for example, teaches (column 11, lines 7-11) that:
