Appeal No. 2004-2315 Application No. 09/348,155 Carricato pertains to a method and apparatus for delivering sheets from a printing unit to a pile of sheets. Carricato’s apparatus includes an intermediate transfer cylinder 26 for transferring a sheet from a first chain 16 to a second chain 34, and for slowing the sheet down as it is deposited on the pile of sheets 38. To this end, the transfer cylinder includes a first gripper 42 for gripping the leading edge of a sheet to be transferred, and a second gripper 44 for gripping the trailing edge of the sheet. Carricato indicates that engaging the trailing edge of the sheet permits the sheet to be deposited on the pile of sheets without disturbances or flutter (column 1, lines 45-50; column 4, line 61, through column 5, line 2). According to the examiner, it would have been obvious to one of ordinary skill in the art in view of the teachings of Rahe and Carricato “to utilize . . . grippers for gripping a trailing edge of the signatures on the gripper cylinder [of Rahe] as another way to reduce tail-edge flutter” (final rejection, page 5). Discussion We appreciate that the stated purpose of the brush guide 81 of Rahe is to minimize the whipping around of the trailing ends of sheets when they are released from between the tapes 13 and 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
