Apparatus for double roller chill casting of continuous metal foil

An apparatus for double roller chill casting of continuous metal foil comprising:

• a plurality of substantially parallel mounting members;
• first and second bearing members slideably mounted on said mounting members;
• first rotary chill roller member rotatably mounted on said first and second bearing members;
• third and fourth bearing members fixedly mounted on said mounting members;
• second rotary chill roller member rotatably mounted on said third and fourth bearing members;
• a yoke member fixedly mounted at each end thereof to said mounting members;
• a bar member disposed laterally adjacent to and spaced apart from said first roller member, said bar member attached at the ends thereof to said first and said second bearing members;
• positioning and restoring means disposed between said bar member and said yoke member for urging said bar member away from said yoke member and toward said second roller member and for maintaining said first roller spaced apart from said second roller member by a selectably variable minimum spacing;
• means for synchronously contrarotating said first and said second roller members;
• and
• means for delivering molten metal between said first and said second roller members;
• whereby when molten metal is delivered between the contrarotating roller members and material between said roller members exerts a displacing force to move said first roller member away from its position of minimum spacing from said second roller member, said restoring means exerts a force on said bar member to slideably urge said first and said second bearing members and said first roller member toward said second roller member to establish a dynamic steady state spacing between said first and said second roller members to produce continuous metal foil of substantially uniform thickness equal to said dynamic steady state spacing.
