ABSTRACT:
A plurality of residual strand removing devices for roving bobbins, which correspond in number to the number of fiber types of residual strand of the roving bobbins, are disposed in a transfer line for transferring the spent roving bobbins from a fine spinning frame to a roving frame. The residual strand removing devices are disposed in series to correspond to the respective fiber types. A control unit is arranged for selectively operating the residual strand removing device corresponding to the detected fiber type of the residual strand of the roving bobbin. The residual strand removing device includes a dust collecting box, a lower suction opening, and an upper exit opening. A lower air passage connects the suction opening and an inlet side of the dust collecting box. An upper air passage connects an outlet side of the dust collecting box and the exit opening. A filter, which can prevent passage of the removed residual strand, is disposed in the dust collecting box for partitioning the same into the inlet and outlet sides. A blower is arranged for supplying air flowing from the suction opening through the dust collecting box toward the exit opening.
