ABSTRACT:
An apparatus for removing residual rovings on roving bobbins in a most efficient manner. A roving bobbin has an annular sticking cloth secured to a portion of the peripheral surface thereof for attaching of a wind-starting end of a roving wound around the roving bobbin. The roving bobbin is rotated in a direction in which the roving is wound around the roving bobbin. A jet of air is directed toward the sticking cloth substantially in a tangential direction thereof in such a manner as to oppose the rotation of the roving bobbin, thereby removing residual portions of the roving attached to the surface of the sticking cloth. The apparatus is adapted to be incorporated in a bobbin conveyance device and has a flocked belt for removing residual rovings on roving bobbins and adapted to travel in parallel with a plurality of roving bobbins which are being conveyed by bobbin hangers while being rotatably hung therefrom; a rockable frame for urging the roving bobbins against the flocked belt through presser members; and a comb wheel adapted to rotate at a peripheral speed greater than the travelling speed of the flocked belt while being in contact at its comb-like tip portions with the flocked belt for stripping off the residual rovings attached to the flocked belt.
