Appeal No. 1998-0514 Application 08/523,907 cylinders, cutter holders and counterweights of German ‘516 from the same composite fiber material having a heat expansion coefficient substantially equal to or less than 0 mm/K, as now claimed. Accordingly, we will not sustain the standing rejection of claim 1, or claim 2 that depends therefrom, as being unpatentable over the collective teachings of German ‘516 and Gomi. Independent Claim 3 Claim 3 calls for a cross cutter comprising, inter alia, cutter cylinders formed of a composite fiber material having a heat expansion coefficient A, and cutter holders formed of a composite fiber material having a heat expansion coefficient B, with A being different than B, such that the difference in heat expansion coefficients creat[es] an expansion differential between said cutter cylinders and said cutter holders at elevated temperatures resulting in the stress of both the cutter cylinder and the cutter holder thereby increasing the rigidity of the cutter holder. German ‘516 does not disclose that the cutter holders are formed of composite fiber material, or that the heat expansion coefficients of the cutter cylinders and cutter holders differ -9-Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
