Abstract
A method of producing continuous lengths of metallic strip comprises the steps of forming a spray of molten metal particles, causing the particles to be deposited onto a surface of a hollow receptor roll, rotating and internally heating the receptor roll to form continuous lengths of metallic strip, holding the deposited particles in contact with the receptor roll surface by means of a roll positioned immediately upstream of the knife in the direction of rotation of the receptor roll, and peeling from the receptor roll surface such continuous lengths of metallic strip by means of a knife positioned adjacent to or in contact with the receptor roll surface. Apparatus for performing this process is also disclosed.

An apparatus for producing strip comprising:
- atomizing means for producing a spray of metallic particles or droplets at elevated temperatures;
- a hollow receptor roll positioned below the atomizing means on which the metallic particles or droplets are received;
- and
- heating means positioned within an interior of the receptor roll and operable to apply heat to an external surface of the receptor roll on which the metallic particles or droplets are deposited.
