4.INTRODUCTION When sheet is entered between a pair of rolls and any kind of force applied to that sheet, like that generated when making a reduction, the rolls, since they are supported at the roll ends, will bend around the sheet. This will tend to make the sheet relatively thick in the middle and thin on the edges. On thin sheet, this will be seen …
