Abstract: The invention relates to a heat transfer device, in particular for use in a strand-form material processing apparatus, wherein said apparatus is in particular equipped to process elongated strand-form material. The heat transfer device has a heat transfer medium and is equipped to process a first section of strand-form material, in particular a first section of wire, wherein said first section of strand-form material has a first output temperature. The heat transfer device is equipped to change the first output temperature, in particular to reduce the first output temperature, by conducting a flow of energy. The heat transfer device is further equipped to process a second section of strand-form material, in particular a second section of wire, wherein said second section of strand-form material has a second output temperature and wherein the second output temperature is lower than the first output temperature. Furthermore, the heat transfer medium is equipped to conduct the flow of heat to the second section of wire and in particular to increase the second output temperature.
