The invention relates to a clamping cylinder () comprising a body () and a movable assembly () contained in a receiving chamber () of the body, rotatable and translatable relative to the body along a predetermined movement axis (V), the cylinder comprising guide means () in order to guide the movable assembly between a clamping position and a free position. The guide means comprise: &#x2014;at least one cylindrical roller (A-D) arranged on the body of the cylinder such that the axis of the roller is essentially perpendicular to the movement axis (V), &#x2014;a rod () of the movable assembly extending along the movement axis and being configured so as to comprise at least one movement portion () having a polygonal section in a plane normal to the movement axis, the section comprising at least one rectilinear edge, the movement portion () being configured such that said section follows an essentially helical base line around the movement axis over at least a fraction () of the portion, the rod () and the rollers (A-D) being positioned such that a roller is arranged across from each of the sides of the polygonal section.

The present invention relates to a rolling device including a stationary first assembly (), comprising at least one first rolling cylinder (), and a movable second assembly (), comprising at least one second rolling cylinder (). The second assembly () is movable along at least one degree of freedom relative to the stationary first assembly () such that the axis (X) of the second cylinder () is movable relative to that of the first cylinder () so as to control the distance between the cylinders (). Said rolling device is characterized in that it includes: a resilient contact means () that exerts a first force on the movable assembly (), said resilient contact means () being configured so as to give way when the reaction force exerted by the movable assembly () on these latter is greater than a predetermined threshold force; and a control means () that exerts, on the movable assembly (), a second force having a component essentially opposite the force exerted by the resilient contact means ().
