Abstract: An apparatus for removing a residual roving attached to a roving bobbin to obtain a blank bobbin, including a rotary driving device for rotating the roving bobbin alternately in a forward direction and a reverse direction, and a device for completely removing the residual roving strongly attached to a roving wind assisting cloth provided on the blank bobbin. A suction nozzle for sucking the roving bobbin is moved to a position where a tip of the suction nozzle comes close to the roving wind assisting cloth, so that the residual roving strongly attached to the cloth can be completely removed by the suction nozzle as rotating the roving bobbin.

Abstract: A clearer for draft rollers is provided, wherein the material for a cloth guide urging a clearer cloth onto draft rollers is changed to an elastic element having an outer shell composed of a flexible sheet made of sponge, foam rubber, foam urethane, plastic, rubber and the like and containing gas, liquid, gel, sol, powder, fine particles, and the like disposed at the back of the clearer cloth where the clearer cloth does not directly urge the draft rollers, in an appropriate length corresponding to the draft rollers whereby the need for the work of changing the cloth guide position is eliminated even if the roller gauges between the draft rollers are changed, and which prevents scraps of fiber and dust from accumulating as floating fibers in the cloth guide.

Abstract: A remained roving bobbin exchanging device for making all the roving bobbins to be transported to a roving frame into vacant bobbins and discloses the remained roving bobbin exchanging device comprising a fixing or removal device for detecting the bobbins having the remained rovings adhered thereto on the bobbin transporting line and exchanging them with vacant bobbins and a tray transporting device for receiving the remained roving bobbins from the fixing or removal device and supplying the vacant bobbins to the fixing or removal device, in which the tray transporting device is made such that a tray can be circulated and at the same time the remained roving cutter device and the remained roving removal device are arranged to remove the remained roving from the remained roving bobbin.

Abstract: A residual roving clearing apparatus for clearing a residual roving remaining on a roving bobbin. The residual roving clearing apparatus comprises a bobbin holding device for rotatably holding a roving bobbin, a cutting device for cutting layers of coils of residual roving remaining on the roving bobbin held by the bobbin holding device, and a rotary brush device for clearing the residual roving from the roving bobbin. The residual roving clearing apparatus is capable of efficiently clearing the residual roving from the roving bobbin by cutting layers of coils of the residual roving along a cutting line parallel to the axis of the roving bobbin held by the bobbin holding device, and stripping off the cut layers of coils of the residual roving from the roving bobbin by the rotary brush of the rotary brush device.

Abstract: A cop magazine for use in association with an automatic winding apparatus the cop magazine including an open-topped cylindrical drum; a tube creel provided inside the cylindrical drum, the creel including cells adapted to house a plurality of cops individually; a rotating member for rotating the tube creel intermittently cop by cop; a suction cap provided at the top end of a suction pipe passed through the tube creel, the suction cap including a slit faced to the delivery-ready position and the delivery position in the tube creel; and a rotary blade for opening and closing the slit so as to release and retain the yarns, the rotary blade being operable in association with the rotation of the tube creel. This structure provides a cop magazine having a simplified construction whereby the yarn ends leading from the cops are retained under suction during movement of the cops from the magazine to the winder.

Abstract: A bobbin conveying apparatus comprising a plurality of trays each of which has a bobbin supporting pin insertable in the bobbin; a pair of guide rails assembled in loops for guiding the trays; a round belt running along the guide rails, the belt being kept with the bottom surfaces of the trays so that the trays are frictionally moved in accordance with the movement of the belt; a mechanism for stopping the bobbin so that the belt continues to run away from the arrested bobbin; and a bobbin take-up means for taking up the arrested bobbin from the tray.

Abstract: A system for delivering packages wound by ring spinning frames to an automatic winder including cop magazines, wherein the leading yarn end of each package is caught and previously put into the top opening of the bobbin. The system includes a disposal machine for disposition of leading yarn end; a circulating conveyor line laid along the row of cop magazines, and provided with circulating trays for transporting packages from the disposal machine; and a transfer machine arranged so as to move along the row of cop magazines freely in opposite directions of travel on the conveyor line for transferring each package from one tray to any cop magazine as desired.

Abstract: A bobbin feeding device includes a plurality of trays placed on a running belt under guidance of the side walls of the feeding device. Each tray includes a seat having a larger diameter than that of the bobbin, a bobbin supporting pin erected on the seat, and a boss having a smaller diameter than the bottom diameter of the bobbin. A shovel is pivotally connected to a terminating end of the bobbin feeding device. The shovel includes a groove having a width sufficient to enable the boss of the tray to fit into it. An actuator rotates the shovel so that each bobbin is scooped from its tray and slid down the shovel to a downstream production line.
