Pressure, frictional stress in the rolling direction and that in the width direction have been measured in the cold rolling of aluminum strip and billet by a new stress sensor developed by the authors. Characteristics of the frictional stress distribution in cold rolling have been elucidated. Frictional stress in the rolling direction is almost constant from the entrance to the neutral point in the contacting arc, both in strip and billet rolling. On the other hand, frictional stress in the width direction increases from the centerline to the edge part and its peak lies in the central part of the contacting arc in strip rolling. However, in billet rolling, it has two peaks in the rolling direction and its value does not vary from the centerline to the edge part. This may be related with the metal flow to the width direction in billet rolling.
