  • Patent number: 5918541
    Abstract: There is described herein a method and apparatus for capturing the heat from the web in a web printing system, storing this heat, and then using it to warm the chill rolls to prevent condensation. Particularly, a heat storage tank is used in conjunction with a chill roll cooling system. During startup, the heat from the web is stored in this tank until the reservoir in the tank reaches a pre-set temperature, at which time the chilled water from the chill system is directed to the chill rolls. At each web stoppage, the water from this heat storage tank is flushed to the chill rolls to keep the chill roll temperature above the condensation temperature.
