The present invention is accordingly based on the object to provide a method and apparatus irit the ■ Materials mentioned, for example, flawlessly and without Broken edges can be rolled.

This gave up is achieved by "a process which overall result. Is features that are performed with the object to be rolled parallel to its longitudinal edges at the same side boundary elements by the pair of rollers"

The invention is used to purify this process proposed a device which is characterized that the rollers are provided with mutually aligned incisions in their side areas, in which side limiting elements are movable in the direction of the respective direction of rotation of the rollers, like border pieces, endless strictness of side borders, Side boundary rings o »avl. intervening c-are arranged.

As can be seen from Eigv 1, the result for the material to be rolled is a pass-through gap which is precisely delimited on all sides and which not only permits appropriate rolling of the material, but also at the same time ensures appropriate edge delimitation.

It can readily be seen that the incisions 14 of the IYaI- ^ en bury their lateral closure with essentially constant adaptability, as it is given on known oil roller mills, but with the device according to the invention, the side of the rolled piece is kept constant and a remarkable reduction in the risk of broken edges is achieved.
