Appeal No. 2006-0774 5
Application No. 09/952,349
Robertson, 169 F.3d 743, 745, 49 USPQ2d 1949, 1950-51 (Fed. Cir.
1999).
While the desire in the yarn winding processes described in
both Mayer and Lieber is to obtain a stable package build, a
uniform package density, as well as satisfactory unwinding
characteristics during a later further processing step, neither
of the applied patents achieves their desired results by using a
method of winding exactly like that defined in appellant’s claims
on appeal. In the claimed invention, the stroke modification
function (Z) which is utilized to vary the length of the
transverse stroke of the traversing yarn guide (3) is determined
from a predetermined mass distribution (F) of the yarn on a
hypothetically wound ideal yarn package. As noted particularly
in claim 1, the mass distribution (F) of the yarn on the
hypothetically wound ideal yarn package is “computed by the steps
of predetermining a desired value of the mass distribution
(Fdesired) from predetermined winding parameters (E) and then
computing the mass distribution (F) while maintaining the limits
of the desired value of the mass distribution (Fdesired).” While
both Mayer and Lieber periodically alter the length of the
