A method of controlling a converting line having a rewinder, accumulator, and downstream equipment includes: providing upper and lower target limits for the accumulator level; determining the slowest maximum speed of the downstream equipment; determining the fastest minimum speed of the downstream equipment; monitoring the speed of the rewinder and the actual level of the accumulator; generating a master speed reference value to control the downstream equipment which: (i) corresponds to said slowest maximum speed of the downstream equipment if the actual accumulator level is greater than the upper target limit; or (ii) corresponds to the fastest minimum speed of the downstream equipment if the actual accumulator level is less than the lower target limit; or (iii) is based on the actual production speed of the rewinder if the actual accumulator level is less than the upper target limit and greater than the lower target limit for the accumulator.
