<p>In apparatus having at least two roll pairs and/or stretch rolls each having a driving means with an amplifier for speed control, the speed control reference for each drive is developed by summing signals developed in adjacent control circuits such as to obtain a relationship in which, for example, for the second drive the signal is V0(1 + S1) (1 + S2) where V0 is a basic speed reference signal and S1 and S2 desired relative speed differences for first and second drives to thereby permit speed adjustments.</p> |
