1596, 1598 (Fed. Cir. 1988) and In re Lintner, 458 F.2d 1013,
1016, 173 USPQ 560, 562 (CCPA 1972).
Independent claim 13 (the only independent claim on
appeal) reads as follows:
A method for manufacturing laminated, disposable
absorbent product, each absorbent product comprising a
fluid-permeable cover layer and a fluid-impervious
backing layer in a parallel and in a spaced apart
relationship, and an absorbent core between said layers,
one of said layers having two opposite edges with
inflected contours, said absorbent core being in a
predetermined positional relationship with respect to
said opposite edges, said method comprising the steps of:
- providing a continuous web having a laminated
structure, including a laminae of fluid-permeable
material and a laminae of fluid-impervious material;
- longitudinally cutting said continuous web
according to a cyclic pattern comprising a combination
of line segments corresponding to a selected section of
said opposite edges, thereby dividing said web in two
strips, each strip having a patterned longitudinal edge
whose outline corresponds to said cyclic pattern;
- reassembling said strips in a parallel and in a
selected phase relationship, with the longitudinal edges
thereof which are opposite said patterned edges being
placed in adjacency to produce a compound web having
longitudinal edges formed by said patterned edges which
are longitudinally matched to produce repeatedly said
selected section, said compound web having laminated side
edge portions;
- applying absorbent cores in a spaced apart
relationship to said compound web at positions selected
in accordance with said predetermined positional
relationship;
