Application 10/631,320
29. The method of making a Saxony carpet comprising the steps:
a. forming an untwisted core strand comprising at least one member
selected from the group consisting of a natural or synthetic fiber;
b. forming a wrapper yarn comprising at least one base synthetic fiber
material, and a heat activated binder fiber having a melting point at least
20ēC lower than the base synthetic fiber;
c. wrapping the wrapper yarn about the core strand, forming an untwisted
wrapped singles yarn;
d. heat setting the untwisted wrapped singles yarn at a temperature
sufficient to melt the heated activated binder material, then subsequently
cooling and solidifying said melt, thereby constricting the base synthetic
fiber component of the wrapper yarn about the core strand and securing it to
the core strand;
e. incorporating the untwisted heat-treated yarn into a backing material as
loops;
f. cutting the loops to form vertical tufts; and
g. dyeing and finishing.
The Examiner relies on the evidence in these references:
Katagi JP 2-300340 A Dec. 12, 1990
Bowers WO 99/14408 A1 Mar. 25, 1999
The Examiner applies Katagi1 in view of Bowers and Bowers in view
of Katagi to all the claims under 35 U.S.C. § 103(a), the two grounds of
rejection submitted for review on appeal by Appellant (Answer 3-7; Br.
4-5).2 The claims are argued as a group in each ground by Appellant and
thus, we decide this appeal on independent claim 29. 37 C.F.R.
§ 41.37(c)(1)(vii) (2005).
1 We considered the translation of Katagi prepared for the USPTO by
McElroy Translation Company (Washington, DC, March 2006).
2 The ground of rejection of claim 29 under 35 U.S.C. § 102(b) over Bowers
is withdrawn by the Examiner (Answer 2).
