Claims :

1. A twin roll strip casting machine having a pair of edge containment assemblies abutting against the ends of the roll barrels at opposite ends of the rolls, each of the assemblies comprising a- face portion of refractory material supported by a backing plate, and means are provided for oscillating the assemblies, characterised in that a source of oscillation is arranged to oscillate both assemblies in directions parallel to the direction of casting with the face portions remaining in contact with the ends of the roll barrels.

2. A twin roll strip casting machine as claimed in claim 1, characterised in that the two assemblies are mounted on respective support arms which are, in turn, connected to a further arm which, in use, is vibrated by said source.

3. A twin roll strip casting machine as claimed in claim 2, characterised in that the said further arm is pivotable by the source about an axis extending parallel to the roll axes.

4. A twin roll strip casting machine as claimed in claim 2, characterised in that the support arms are pivotable about axes extending parallel to the
direction of casting, and means are provided to pivot them in the directions to abut the assemblies against the ends of the roll barrels.

5. A twin roll strip casting machine as claimed in claim 4, characterised in that each support arm is connected at a position on the opposite side of the pivot from the assembly to a fluid operable piston-cylinder device arranged to pivot both arms towards and away from the roll ends.

6. A twin roll strip casting machine as claimed in any preceding claim, characterised in that each support arm is connected to the backing plate of the respective assembly through a gimbal mechanism which permits relative movement between the arm and the backing plate in two mutually perpendicular directions.

7. A twin roll strip casting machine as claimed in any preceding claim, characterised in that each assembly has means for heating the face portion and means for cooling the backing plate.

8. A twin roll strip casting machine as claimed in claim 1, characterised in that the means for heating the face portion comprises electrical heaters
associated therewith and the backing plate has
provision for the flow of cooling fluid therethrough.

9. A twin roll strip casting machine as claimed in any of the claims 1 to 6 , characterised in that each assembly has a face portion of porous refractory material and means for forcing inert gas through the refractory material towards the rolls.

10. A twin roll strip casting machine as claimed in any preceding claim, characterised in that the source of oscillation is capable of oscillating the assemblies at up to ultrasonic frequencies.
