| 摘要 |
The invention concerns a cooled mandrel for winding a band-type product into a coil, including a set of adjacent segments ( 2 ) mounted to slide radially on a central shaft ( 1 ) and fitted each of a cooling circuit ( 24, 24 ') having two orifices, respectively an inlet orifice ( 75 ) and an outlet orifice ( 75 '), connected each, by a connection fitting ( 7, 7 ') having a variable length, to a supply ( 5 ) or exhaust ( 5 ') duct, respectively of a heat exchanging fluid. According to the invention, the linking fittings ( 7, 7 ') corresponding to each segment ( 2 ) are connected to a distribution part ( 6 ) threaded on a lateral face ( 13 ') of the shaft ( 1 ), wherein emerge transversally both ducts, respectively the supply duct ( 5 ) and the exhaust duct ( 5 '), which are arranged inside the central shaft ( 1 ).
