A draft device comprising: a plurality of pairs of the draft rollers arranged in a travelling direction of a fiber bundle between an upstream end and a downstream end of the draft device, wherein each of the plurality of pairs of the draft rollers includes a top roller (21, 22, 24, 25) and a bottom roller (26, 27, 28, 29), and a fiber control member, comprising: a first end portion; a fiber bundle curving section adapted to curve a transportation path of the fiber bundle to be drafted by a draft device, the fiber bundle curving section being formed on the first end portion; a second end portion located opposite to the fiber bundle curving section; and a cutout formed at the second end portion, the cutout being cut out towards the first end portion, characterized in that with the cutout fly wastes can be prevented from accumulating around the fiber control member and the draft rollers, the draft device further comprises attachment grooves adapted to receive the fiber control member for holding the fiber control member and in that the fiber control member is formed of a plate-like member and is arranged between a first bottom roller arranged first from the upstream end of the draft device and a second bottom roller arranged second from the upstream end of the draft device, the fiber bundle curving section is a portion formed by folding the plate-like member, and the fiber control member is arranged so that an outer surface of the folded portion of the fiber bundle curving section makes contact with the fiber bundle, the fiber bundle curving section thereby curving the transportation path of the fiber bundle and wherein the fiber control member is preventing the fiber bundle from falling off. a plurality of pairs of the draft rollers arranged in a travelling direction of a fiber bundle between an upstream end and a downstream end of the draft device, wherein each of the plurality of pairs of the draft rollers includes a top roller (21, 22, 24, 25) and a bottom roller (26, 27, 28, 29), and a fiber control member, comprising: a first end portion; a fiber bundle curving section adapted to curve a transportation path of the fiber bundle to be drafted by a draft device, the fiber bundle curving section being formed on the first end portion; a second end portion located opposite to the fiber bundle curving section; and a cutout formed at the second end portion, the cutout being cut out towards the first end portion, a first end portion; a fiber bundle curving section adapted to curve a transportation path of the fiber bundle to be drafted by a draft device, the fiber bundle curving section being formed on the first end portion; a second end portion located opposite to the fiber bundle curving section; and a cutout formed at the second end portion, the cutout being cut out towards the first end portion, characterized in that with the cutout fly wastes can be prevented from accumulating around the fiber control member and the draft rollers, the draft device further comprises attachment grooves adapted to receive the fiber control member for holding the fiber control member and in that the fiber control member is formed of a plate-like member and is arranged between a first bottom roller arranged first from the upstream end of the draft device and a second bottom roller arranged second from the upstream end of the draft device, the fiber bundle curving section is a portion formed by folding the plate-like member, and the fiber control member is arranged so that an outer surface of the folded portion of the fiber bundle curving section makes contact with the fiber bundle, the fiber bundle curving section thereby curving the transportation path of the fiber bundle and wherein the fiber control member is preventing the fiber bundle from falling off.
