Appeal No. 2006-1956
Application No. 09/935,917
1 The Invention
2 Appellant's invention is an apparatus and method for selectively
3 perforating sheets as a group of sheets moves successively through the
4 perforator. The invention is particularly advantageous for applications in
5 which only specific pages of printout letters with many pages require
6 perforation. A single type of paper can be used for the entire print job, while
7 only the desired sheets are perforated (Specification 2).
8 Claim 27 is illustrative of the claimed invention and reads as follows:
9 27. A system for selectively perforating sheets of
10 paper of a group of sheets, wherein sheets to be
11 perforated are selected as the group is moving
12 successively through a perforating device, the
13 perforating device including a first perforating tool
14 for perforating paper and a control unit for
15 controlling the perforating tool, wherein the first
16 perforating tool perforates the paper along a
17 direction of the movement of the sheets, the system
18 comprising:
19 means for successively receiving a plurality
20 of sheets of paper as input to the perforating
21 device; and
22 means for positioning the first perforating
23 tool in either a perforating position to perforate
24 paper or a neutral position to allow paper to pass
25 unperforated, including:
26 means for receiving at the control unit as the
27 group of sheets moves through the perforation
28 device, for at least a first sheet, a first control
29 signal based on information specific to the first
30 sheet;
