In this note is suggested a modification to overcome the difficulty met in the application of Bland and Ford's simplified theory of strip rolling to passes where heavy back tensions are applied.
An equation for the roll force is evolved and compared with those of Orowan and of Bland and Ford. Experimental and calculated values of roll force given show an accuracy to within 10 per cent.
