Abstract: A pair of tangential belts disposed for parallel movement on the left and right locations for individually driving a pair of left and right spindle trains disposed in a back-to-back relationship to each other are individually driven by means of a pair of motors at the opposite ends of a machine base, and a right take-up mechanism train is driven by a speed change gear connected to a driving pulley for a belt while a left take-up mechanism train is driven by another speed changing device connected to a turn pulley for a belt, the speed changing device and being disposed collectively at an end of the machine base.

Abstract: A robot apparatus for a double twister, which can travel along the units of the double twister, is provided with an operating arm for drawing a yarn end from a feed package, a suction arm for drawing a yarn end from a winding package, a yarn hook portion for hooking both the drawn yarn ends, and a piecing device for piecing both the yarn ends at the hook portion. The robot apparatus is operated to enable formation of a full winding package having a predetermined winding amount from a plurality of feed packages without requiring a yarn length counter.

Abstract: A device for catching a yarn upon yarn break in a two-for-one twister, comprising a drop wire which moves down upon break of a yarn, and a contacting member secured to the drop wire and adapted to be contacted with an upper end portion of a tenser cap.

Abstract: A method for winding a fixed length of yarn on a yarn-supply package in an apparatus connecting an automatic winder or an innovation spinning machine having a winder with a two-for-one twister. The method comprises dividing a single yarn-supply package transferred from a winder side to form a plurality of twist-yarn packages on the two-for-one twister side.

Abstract: A two-for-one twisting machine including a plurality of twister units arranged in a back-to-back relationship in two rows in constituted such that a support shaft extends above friction rollers in each of the rows of the twister units and individual cradle arms are supported turnably at base end portions thereof on one of the support shafts on the back side.

Abstract: An automatic winder and a two-for-one twisting machine are interconnected by a yarn supply package exchanging device for a set of two packages arranged in two upper and lower stages which is located between the automatic winder and the two-for-one twisting machine. Doffed packages at the winder side are put on a yarn support fitted on a tray by the yarn supply package exchanging device and are transported and supplied to a spindle of the two-for-one twisting machine.

Abstract: A package feeding method and apparatus for a yarn twisting machine having a large number of two-for-one twisters of two stage yarn supply type. A package is fed after an end of yarn of the package has been wrapped in several turns of a yarn layer non-existing portion of the package.

Abstract: An apparatus for transporting fully wound packages doffed on and discharged from a spinning frame. The transporting apparatus of the present invention includes a main conveyor, sub conveyor and a lifter, wherein the two conveyors are individually controlled such that a package which is to be transported next by the lifter is always held ready at a predetermined stand-by position. The lifter is able to change the orientation of doffed packages during lifting operation of the package.

Abstract: An apparatus for transporting a bobbin between a winder and spinning frame. A curved transporting path is provided contiguously between a vertical transporting path and a horizontal transporting path, and a conveyor belt is disposed to extend along these paths. A cover which covers the bobbin transporting paths along a length thereof is provided.

Abstract: A device for discriminating and distributing the bobbins, which are discharged from a textile machine such as an automatic winder, in accordance with the quantity of yarns wound on the bobbin and/or the kinds thereof. The device includes sensors, a bobbin chucking means made movable which chucking the bobbin to distribute the bobbin, and guide means for guiding the movement of the chucking means operated in accordance with the instruction of the sensors.

Abstract: A cop supplying device for feeding a cop to a carrier member which is adapted to convey the cop to an automatic winder. The cop supplying device comprises a storing box for storing a plurality of cops, a cop transporting device for feeding the cops to the cop box, a device for detecting and ejecting wrong cops interposed between the cop box and the transporting device, and a releasing device for releasing the cops from the cop box and fitting the cop on the carrier member.

Abstract: A doffing apparatus in an automatic winder having a plurality of winding units. A transporting conveyor for conveying doffed full packages is provided to extend along the units and package guide path is provided between the transporting conveyor and a position wherein full packages are discharged from the winding unit. A stock device for temporarily stopping the full packages is provided on the guide passage.
