Appeal No. 1998-2551 Page 6
Application No. 08/787,624
American Viscose discloses a weftless fabric and in
particular a weftless tape formed of strands bonded together
in parallel relation and adapted for heavy duty strapping. As
shown in Figure 3, each of the strands 17 and 18 each comprise
a bundle of substantially parallel continuous filaments having
intermediate portions in the forms of loops 22 extending
laterally and overlapping and engaging filaments of adjacent
strands. American Viscose teaches (page 2, lines 85-91) that1
the strands can be produced from a yarn composed entirely of
aligned continuous filaments passed in a highly relaxed,
tensionless state and simultaneously subjecting the yarn to a
stream of air that causes some of the filaments to be blown
out of the strand to form protruding loops in the finished
yarn.
The appellant argues (brief, p. 3) that the yarns of
American Viscose are plied yarns, not core and effect yarns as
claimed. The examiner's response (brief, pp. 3 and 5) to this
