Abstract: Apparatus is provided for cooling rolled wire after rolling by the application of a liquid treatment medium, which apparatus requires substantially less space and retention time for treatment than previous devices utilizing liquid mediums, but which still accommodates the rolled product issuing from a high speed large capacity production line. This is achieved by coiling the wire and simultaneously continuously immersing it in the container holding the liquid treating medium, so that at the moment each coil of wire is completed, it is also properly treated. Also included are means for sequentially coiling and removing each coil of rolled wire from the liquid treatment container.
