A speed control system for use in a continuous strip manufacturing
apparatus such as a continuous casting and rolling apparatus having a
plurality of work means including roll stands through which metal rod or
other elongate material is continuously moved. The control system includes
a function generator providing a speed control signal to the speed
regulator means of one roll stand which is linearly proportional to the
speed of the preceding work means and which is also linearly proportional
to the sum of an operator selected arbitrary signal voltage proportional
to a desired speed ratio of the one roll stand to the preceding work means
and a looper signal voltage proportional to the variation from a
preselected position of the position of a loop of elongate material formed
between the one roll stand and the preceding work means. The control
system thus acts to maintain a desired proper relation between the speeds
of the one roll stand and the preceding work means while providing
compensating variations in the speed of the one roll stand with variations
in the position of the loop of elongate material from a preselected
position.
