    the hot rolling mill is coiled for transport to the cold mill which might be on the same site or elsewhere. Cold mills in a wide range of types and sizes are available some are single stand others 3 stand and some 5 stand (Figures 1301.02.03 and 1301.02.04). Cold rolling speeds vary but modern mills operate at exit speeds as high as 3000 m per Lunn bar fitted parallel to the mill rolls and positioned so that the operator works over it. The Lunn bar has proved effective in reducing the number of fata l and serious maiming injuries at two roll mills from their historical level of about 20 per year in the 1950s60s
