PURPOSE: To facilitate the repair and inspection of a fine spinning frame, in a carrier device which carries fine spinning bobbin yarn manually doffed with the fine spinning frame to automatic winder side, by providing a doffing fine spinning bobbin yarn carrier passage at a height which is nearly equal to that of a spindle.

CONSTITUTION: A fine spinning frame S provided with plural weights, which produces fine spinning bobbin yarn (actual bobbin) and an automatic winder W are connected to each other. A doffing fine spinning bobbin yarn carrier passage 1 disposed sideways along the respective weights of the fine spinning frame S is constituted as a transfer band provided with pegs 2 for bobbin device mounted on the band at equal intervals. The bobbin yarn carrier passage 1 is generally stopped, and is moved to automatic winder W side after completion of doffing to feed an actual bobbin B. With this constitution, the installation height of the carrier passage 1 is set at a height which is nearly equal to those of the respective spindles of the fine spinning frame S or which is a little lower. It is possible to facilitate the repair and inspection of the fine spinning frame S without allowing obstacles on the downside of the fine spinning frame.
