The relationship between rolling load and bending load for a strip of a desired shape and width passing through a rolling mill is predetermined and the appropriate relationship for a given strip automatically maintained. The information is stored in a computer which is fed with an electrical signal representing the rolling load, and supplies the required bending load signal, which is directed via a positive or negative closed loop servochannel to control the bending load. The computer can also be fed with information relating to other relevant parameters, e.g. material, width, type of lubrication, temperature.
