<p>The present invention is with respect to cooled rolls, and more specially distributor rolls with a metallic outer face for the transport of ink or dampening fluid in offset presses. The even temperature distribution over the full press width necessary for printing without any trouble conditions is more specially likely to come to an end when the press is shut down for a short time and when the dampening system is turned off. The heat transfer then taking place from the relatively hot press side frames, the driving and the bearing parts to the cooler roll bodies is responsible for trouble conditions, caused by uneven temperature distribution, when the machine is started up again.</p> |
