A bleeder cord affixing device comprising: a treatment member feeding device (1, 2) for feeding a treatment member in a direction; an affixing roller disposed to extend in a breadth direction across the direction in which the treatment member is fed; a bleeder cord arranging device (14, 15) for guiding and arranging a plurality of bleeder cords with leading ends in parallel rows along the direction in which the treatment member is fed; and an affixing roller moving mechanism rotatably supporting the affixing roller thereon and being operative to move the affixing roller between a pressed position in which the affixing roller is pressed onto the treatment member being fed, to cause the affixing roller to be rotated due to friction with the treatment member being fed, and a standby position in which the affixing roller is moved away from the treatment member; said affixing roller moving mechanism being configured to move the affixing roller in the standby position to the pressed position onto the treatment member being continuously fed, in a state in which the leading ends of the bleeder cords arranged by the bleeder cord arranging device (14, 15) are attached to an outer surface of the affixing roller, and to cause the affixing roller to rotate due to friction with the treatment member to thereby press the leading ends of the bleeder cords onto the treatment member so as to affix and adhere the bleeder cords continuously to the treatment member; wherein: the leading ends of the bleeder cords have adhesive nature; wherein the affixing roller is rotatable in one direction only, which direction is a direction in which the affixing roller is rotated due to the friction with the treatment member, created when the affixing roller is pressed on the treatment member being continuously fed; and wherein a pass roll extends in parallel with, and is of a length substantially equal to, the affixing roller supported on the affixing roller moving mechanism, the pass roll being configured to guide the bleeder cords arranged in parallel rows by the bleeder cord arranging device (14, 15) to the affixing roller, the pass roll being rotatable only in one direction which is the same as the direction in which the affixing roller is rotatable. a treatment member feeding device (1, 2) for feeding a treatment member in a direction;
