Abstract: Two rolls, more particularly embossing rolls are provided which are pressed against each other by pneumatic cylinders for the purpose of fashioning a flat material passing between the rolls. The ends of one of the roll axles are journalled in slides which are actuatable by the cylinders in such a manner as to be deflectable in the pressure direction and in the travelling direction of the material. The elastically suspended roll is thus capable of automatically adjusting itself in such a manner that the axles of the two rolls can adjust to irregularities of the flat material and thus allow a disturbance-free and qualitatively optimal treatment of the material.
