A machine for controlling the width of workpieces rolled between horizontal rolls includes a pair of vertical edger rolls which are mounted on respective pivotable arms. The pivots for the arms include an eccentric whereby the rolls can be moved closer together or further apart to accommodate workpieces of different width. A cam mechanism is provided to increase and decrease the separation between the rolls. This mechanism bears against the arms on the opposite sides of the pivots to the edger rolls.
