摘要： An apparatus for removing waste rovings remaining on the roving bobbins, the apparatus comprising a conveyor (C) for transporting roving bobbins hung on hangers (BHG), the conveyor including means for effecting the temporary stoppage thereof; a moving frame (10) and a lifting frame (30) which are respectively equipped with upper bobbin holders (21) and lower bobbin holders (34) for maintaining rotating bobbins; a flocked belt (41) provided between the upper and lower bobbin holders in such a manner that the belt runs tangentially to the bobbins maintained by the upper and lower bobbin holders; and wherein the individual bobbin holders are spaced at intervals corresponding to those of the hangers of the conveyor.

摘要： A method and an apparatus for removing residual rovings on roving bobbins in a most efficient manner are disclosed. 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 comprises: 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; an oscillating 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.
