Abstract
The device of the invention introduces cooling fluid to a rotary mould (41) surrounded by an annular cooling chamber (42). A non-rotatable annular box surrounds the outer wall of the annular chamber, and two annular nozzles (50, 51) rigid with the box (47) discharge in each case into an annular passage (57, 58) disposed between the outer wall and at least one non-rotatable wall rigid with the box. The fluid from the nozzles, after passing through the annular passage (57, 58), passes through an annular inlet zone (46), and through orifices (44, 45) into the annular cooling chamber (42).
