Abstract
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.
Claims4
In a slitting line including an uncoiler, a slitter and a recoiler having a rotatable drum, a coil of metal material carried by said uncoiler, said material extending through said slitter and being cut thereby into multile strands, and strands varying in thickness, the method of coiling said strands comprising the steps:
- (a) securing the ends of each strand to said recoiler drum;
- (b) rotating said recoiler drum to coil at least one turn of each strand around said drum;
- (c) releasing the end of each strand from said drum with said first turns of the strands remaining in contact with the drum;
- and
- (d) rotating said drum in frictional contact with said strand first turns to impart winding rotation to the strands with said drum rotating relative to at least one of said strands to cause each of the strands to be wound upon said drum at substantially the same linear speed as said sheet material is uncoiled during rotation of said uncoiler and passes through said slitter.
