A roll clamp comprising a pair of concavely curved pads for clamping onto opposite sides of a roll. A pair of opposed arm structures extending rearwardly from the pads toward a frame support the pads in spaced opposed and facing relationship. The arm structures are movable toward and away from each other on the frame, whereby the pads may be brought against opposite sides of a roll. At least one arm structure includes an arm base which is mounted on the frame, a forward arm section, and means pivotally mounting the forward arm section on the arm base enabling it to swing in each of opposite directions until reaching defined limit positions. The pivot means is located toward said frame from said pads, and from the load center of any roll clamped by the pads. A spring biases the forward arm section to place it in an intermediate at rest position between these two limit positions.
