A gravure pressure roller with an axis of variable shape, in which the outer jacket (2), rotated coaxially to and inside the jacket (2) of the roller by the shaft (3), is supported at its ends by bearings (10) and at the mid-part by levers (21) coupled in an articulated manner to the mid-part of the shaft (3), so as to be in contact with the inner surface (7) of the jacket (2), contacting the same with the intercalation of bearings (22) and actuators (15) inserted between the shaft (3) and each lever (21).
