ABSTRACT:
The invention relates to a process for automatically controlling the shape of sheet metal produced in a rolling mill, and to apparatus for carrying out the process. The shape of the sheet is sensed by a shapemeter, and each segment of the shapemeter provides an output indicative of the shape of the portion of the sheet passing over that segment. In accordance with the invention, the outputs are converted to electrical signal levels, such as current or voltage levels, and certain ones of the signal levels are averaged, and the averages are compared either with certain other signal levels, or with certain other averages. If the comparisons yield a difference greater than predetermined tolerance levels, control signals are generated to control parameters of the rolling mill.
