advanced and the other drawn back and the roll 11 may be set so that it will be out of
alignment and more tension applied to one end than the other. To move the shaft 20
longitudinally it is provided with a grooved collar 21 into which a roll or the end of a lever
22 engages. The other end of this lever is operated by an adjusting screw 23. By
means of this screw the uneven adjustment can be provided. The tension of the
springs 15 can be increased or decreased to any desired degree by operating the
adjusting screw 17 and the tension at both ends can be evened up in that way.
The examiner's position
The examiner concluded (answer, p. 5) that it would have been obvious at the
time the invention was made to a person of ordinary skill in the art to substitute Wood's
tensioning roll for the spring-biased movable dancer arms of Simmons in Simmons'
cushioning conversion machine.
The appellants' position
The appellants argue throughout both briefs that the claimed movable constant-
entry device is not suggested by the applied prior art.
