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 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 roving bobbin carrier system having a single carrier line for conveying a plurality of full wound roving bobbins from a roving frame to a fine spinning frame and conveying a plurality of unwound roving bobbins from the fine spinning frame to the roving frame with the unwound roving bobbins converted into blank roving bobbins having no residual roving. A stock conveyor is provided at a midway position of the carrier line independently thereof. A residual roving removing device and first and second transfer mechanisms are provided in connection with the stock conveyor to convert the unwound roving bobbins to the blank roving bobbins. Accordingly, the conveyance of the full wound roving bobbins and the unwound roving bobbins can be efficiently carried out through the single carrier line.

Abstract: A cop feeding apparatus for an automatic winder for feeding cops which are carried on trays and conveyed along a conveyance rail automatically to empty spindle portions of cop magazines in the automatic winder while moving along the conveying rail. In this cop feeding apparatus, a cop is pulled out from a tray by a cop draw-out device; a yarn end of the cop is held by a yarn end draw-out device; the cop is then fed to an empty spindle portion of a magazine through a storage device and a retaining/introducing device; a yarn end of the cop is delivered securely to the magazine side by a yarn end guide device; and thus each cop and a yarn end thereof can be fed to an empty magazine spindle portion smoothly without entanglement of cops with each other.

Abstract: The invention provides a cheese transporting processing apparatus for classifying cheeses wound up by winders or the like for different types and packing and carrying out the thus classified cheeses. When a cheese is transported by an overhead conveyor with a type identifying unit, information of a type of the cheese is written into the type identifying unit. In accordance with such type information, cheeses are stocked for different types into a cheese stocker. In response to a demanding instruction from a packing line, cheeses of a specified type are discharged from the cheese stocker and boxed and packed. Such sequence of operations is performed automatically on the cheese transporting processing apparatus.

Abstract: The present invention relates to a cheese conveyor system for conveying cheeses wound by a winder, wherein hangers each supporting a lower portion in an outer peripheral surface of a cheese from opposite sides thereof are provided on a ceiling conveyor, and forks are provided on loaders and unloaders whereby either parallel cheeses or cone cheeses can be conveyed without changing the apparatus structure, and the loaders and the unloaders are of the same construction whereby either function of the loader and the unloader can be accomplished by changing the operating method to reduce the installation costs.

Abstract: The present invention provides an apparatus which employs a mechanical removal system in place of a conventional air jet system, in removing a residual lap on a spool. The residual lap removal apparatus according to the present invention principally comprises a bobbin holder, a rotational brush and a spike roller, wherein the spool on a conveyor is carried to a rotating position of the rotational brush by the bobbin holder, the residual lap on the spool is mechanically removed by the brush, and the lap on the rotational brush is transferred to spike pins on the spike roller whereby the removal processing of the residual lap can be positively carried out.

Abstract: The present invention relates to a cheese stocker for temporarily storing cheeses doffed by a winder, wherein the cheeses are placed on a cheese conveyor through trays to prevent the surface of the cheese from occurrence of mechanical damage or stain, wherein the cheeses are transferred and conveyed by a cheese conveyor, a tray conveyor, a traverser and a transfer machine, and wherein a plurality of stockers are provided along the cheese conveyor to thereby render possible prior-in and post-out conveyance to cheeses between the stockers.

Abstract: A cop sorting and transporting system for a transporting step from spinning machines to winders in a spinning mill. A tab code representative of a type of a yarn of a cop is set arbitrarily to a tab device provided for each of cop magnazines which are provided for accommodating cops therein in order to selectively determine a destination of the cop magazine. The tab code of the tab device can be changed or reset to allow repetitive use of the tab device, which allows common use of the cop magazines to cope with production of many types of spun yarn by small quantities.

Abstract: A bobbin transport system for spinning frames for supplying bobbins from bobbin reservoirs to spinning frames in a spinning mill. The spinning frames are divided into dedicated machine groups and a common machine group or groups. Bobbins are supplied to the dedicated machine groups by way of a main transport path and/or a sub transport path, and a communicating transport path for transferring bobbins from the sub transport path to the main transport path is provided for each of the spinning frames of the common machine group or groups. The bobbin transport system for spinning frames makes it possible to change the allotment of numbers of spinning frames for different types of yarns to be set for the common machine group or groups and to distribute different types of bobbins accurately to predetermined spinning frames thereby to enable production of several articles by small quantities without deteriorating the availability factor of the entire spinning frames.

Abstract: A residual lap clearing apparatus for clearing a residual lap from a lap bobbin. The residual lap clearing apparatus comprises a rotary brush roller for stripping the residual lap off the lap bobbin, a support roller for supporting a lap package for residual lap clearing operation, a brake mechanism for braking the lap package during the residual lap clearing operation, and a comb roller for removing bunches of fibers caught in the bristles of the rotary brush roller off the rotary brush roller. The rotary brush roller surely finds the free end of the residual lap and clears the residual lap perfectly from the lap bobbin.
