PURPOSE: To provide a cut foil yarn-dividing device, capable of surely arranging the cut foil yarns in a parallel order and surely dividing the cut foil yarns by disposing a yarn-arranging guide in addition to a cut foil paper-spreading means, a cut foil yarn-cutting means and yarn-separating elastic disks.

CONSTITUTION: A cut foil paper (yarn) portion adjacent to the right side edge of a selvage-fixing support belt 12 is loaded on a yarn-arranging guide 52, raised in a curved shape and simultaneously forward carried. Therein, the curved raising of the cut foil paper portion is carried out, while the right side portion of the cut foil paper portion is moved to the left side against to the nipping force and carrying force of a pair of yarn nipping and carrying rollers 34, because the left side selvage portion 58 of the cut foil paper portion is fixed to the selvage-fixing support belt 12 to limit the movement. Thereby, the mutually adhered adjacent cut oil yarns 60 are separated from each other, and the cut foil yarns 60 are perfectly cut off.
