Appeal No. 2005-0958
Application No. 09/944,477
“individual thermoplastic fibers of the second web . . . neither
fused nor mechanically entangled tightly with each other between
discrete areas where the first and second webs are joined
together . . . . ” Details of the appealed subject matter are
recited in claim 1 which is reproduced below:
1. A process for manufacturing a composite sheet
capable of elastic stretch and contract in one direction,
said process comprising:
(a) continuously feeding, in the one direction, a first
web capable of elastic stretch and contraction and having a
top surface and a bottom surface;
(b) extending said first web in the one direction
within a range that permits elastic stretch and contraction
of the first web;
(c) continuously feeding a second web capable of
inelastic extension and composed of thermoplastic fibers
along the one direction;
(d) superimposing said second web on at least one
surface of the extended first web and joining said second
web to the first web in an intermittent manner along the one
direction to provide a composite web;
(e) extending the composite web in the one direction
within a range that permits elastic stretch and contraction
of the first web; and
(f) allowing the extended composite web to react by an
elastic contraction force of the first web to thereby obtain
a composite sheet in which individual thermoplastic fibers
of the second web are neither fused nor mechanically
entangled tightly with each other between discrete areas
where the first and second webs are joined together in step
(d).
