A coating system for supplying a coating medium to sheet material in a printing press. The coating system includes a tempering system operable for influencing the temperature of both a coating medium processed through the applicator system and rinsing mediums supplied to the applicator system for cleaning the system. The tempering system includes and intermediate container connected to the metering system of the applicator system, a first storage container connected to the intermediate container for containing a stored quantity of coating medium, and a second storage or discharge container connected to the intermediate container for a rinsing medium. The intermediate container includes a heat exchanger such that upon selected connection of either the first or second storage containers to the intermediate container, the cleaning medium or the rinsing medium can be individually tempered for optimum processing.
A coating system for supplying a coating medium to sheet material during sheet transfer comprising a coating medium applicator system including a form cylinder (2) for applying coating medium to sheet material and a metering system (9) for metering and transferring a predetermined amount of coating medium to one of the form cylinder (2) or sheet material attached to the form cylinder (2);
A method of supplying coating and cleaning mediums to an applicator system of a printing press having an applicator roller and a metering system comprising the steps of providing a first intermediate container for supplying coating medium to the metering system, providing a first storage container for supplying coating medium to the intermediate container, providing a second storage container for containing a rinsing medium, supplying the coating medium from the first container to the intermediate container and then to the metering system, tempering the coating medium by influencing the temperature thereof at a location between the intermediate container and the metering system, interrupting the supply of coating medium from the storage container to the intermediate container and supplying a rinsing medium to the intermediate container and then to the metering system for cleaning the applicator system, and tempering the rinsing medium influencing at said location between the intermediate container and the metering system.
