Abstract
A roller casting method produces a spiral structure, in particular a spiral structure for use in electric machines. Molten metal is supplied between a first roller and a second roller miming opposite thereto, wherein the first roller has first teeth, and the second roller has second teeth, said first and/or second teeth having tooth flanks with cavities for receiving the supplied molten metal. The teeth are designed and aligned such that the cavity of at least one tooth is at least temporarily delimited by the surface of a tooth of the other roller when the rollers are rotating such that the supplied molten metal is molded between the teeth while cooling and is molded into a section of the spiral structure.
