A method by which multiple strands of slit metal material are wound upon the rotating drum of a recoiler. Frictional contact between the recoiler drum and strands cause the strands to be coiled about the drum with relative movement between the recoiler drum and the separate coils of strands occurring to accommodate the varying thicknesses of the individual strands so that the strands are wound upon the drum at substantially the same linear speed.
