Abstract
An arrangement for rolling the frontal end of a deformable sleeve-shaped container jacket comprises a supporting surface which radially supports the container jacket in the area of its end. A ring-shaped cavity is arranged radially adjacent thereto, which cavity is closed at the bottom and open at the top. The cavity has an essentially semicircular cross-section. The cavity is provided in circumferential direction with a plurality of pocket-shaped recesses in the transitional area between the supporting surface and the bottom, between which recesses rolling ridges, as part of the original cavity surface, remain. The purpose of this design is to effect a reduction in the deformation forces when the frontal end of the container jacket is being rolled.
