In this study, the cooling system for the rubber roller in an embossing machine is experimentally examined to reduce the surface temperature increase and extend the working life of the rubber roller. The embossing process generates significant heat, leading to deformation and reduced efficiency of the rubber cylinder over time. In this study, experiments were conducted at a machine speed of 350 m/min, demonstrating that the rubber cylinder begins to deteriorate at a surface temperature of 46 °C under specified pattern density conditions. A cooling system was designed to address this issue, and experiments were conducted with a chiller unit to cool the rubber cylinder from within. The designed system maintained a surface temperature of approximately 5 °C lower than the damage threshold, thus prolonging the operational life of the rubber cylinder. However, operating the rubber cylinder at this temperature is a temporary solution, and further improvements are required for higher machine speeds or increased pattern densities. Future studies could explore the use of chillers with different temperature ranges and flow rates and redesign the experimental setup to enhance heat transfer efficiency. These accomplishments would contribute to the development of an optimized cooling solution for rubber cylinders, ensuring sustained performance under varying operational conditions in embossing machines.
