A takeup drum, particularly for wire drawing machines, having a fluid cooling unit, the drum comprising: a cylindrical body, which is rotatable about a central axis and is supported, through bearings, by the fixed frame of the machine; a chamber that is formed in the body; and a drum cooling unit that is arranged in the chamber. The cooling unit comprises: at least one circular sector that is located proximate to the internal lateral surface of the body and is connected to the fixed frame that supports the cylindrical drum body; and at least one nozzle for introducing the cooling fluid, located proximate to the outer surface of the sector, so as to form a jacket of cooling fluid that flows over the internal lateral surface of the body.
