or chemically aggressive materials. In col. 2, lines 22
through 33, Kobler discloses that a pad 4 is applied to the
surface of the rubber blanket cylinder. The pad may be made
of paper, cardboard, felt, or the like. The pad 4 is beneath
the rubber blanket 5. In col. 2, lines 34 through 62, Kobler
teaches that it has been found that electrostatic charge will
build up on the insulating material forming the pad 4 and the
blanket 5.
Kobler teaches that the surface of the pad 4 which is in
contact with the insulating protective layer has an
electrically conductive layer or coating 6 applied thereon.
Therefore, we find that Kobler teaches that the electrically
conductive layer 6 is between the pad 4 and the protective
coating 3 of the cylinder surface 1.
Thus, we find that Kobler is concerned with drawing off
electrostatic charges that could be built up in between a pad
4 and protective layer 3 to prevent damage due to corrosion.
Kobler is not concerned with the problem of electrostatic
charge building up on the outer surface of the rubber blanket
5. Therefore, we fail to find any suggestion or desirability
