III. Findings of Fact
The record in this application supports the following findings of fact by at least a
preponderance of the evidence:
1. The claim on appeal reads as follows:
Claim 1. A method for manufacturing a pleated filter material from a
thermally bonded non-woven fabric, comprising:
forming a single fibrous web from undrawn and drawn synthetic fibers;
pre-heating the fibrous web;
calendering the single fibrous web between non-heated profiled calender
rolls in a single calendering step without subsequent re-heating, wherein during the
single calendering step, the undrawn fibers in the single fibrous web are bonded in a
tension-free manner between the non-heated profiled calender rolls to form the non-
woven fabric, without inhomogeneities over the cross-section of the non-woven fabric
and without the use of flat bonding, and wherein during the single calendering step,
spacers are formed in the non-woven fabric to thereby form the filter material. (Appeal
