Abstract: An unwinding assisting device for an automatic winder. The automatic winder has a winding position at which a cop of yarn is unwound from a take-up tube supported on a tray. A lifting mechanism raises the tray at the winding position as the cop of yarn is unwound from the take-up tube. A tubular member receives the take-up tube therein. The tubular member has an inside diameter that is smaller than the outside diameter of the cop and larger than the outside diameter of the take-up tube.

Abstract: A yarn unwinding assisting device for an automatic winder comprising a first defining member having an inner diameter defining portion covered over a yarn feed bobbin to define a lower balloon, and a second defining member having a defining member located above the yarn feed bobbin to define a yarn running area and defining an upper balloon, wherein said first defining member is separated from said second defining member to enable following the unwinding of the yarn feed bobbin.

Abstract: A cop changing mechanism for a winding unit, for transferring a tray supporting a cop in an upright position from a waiting position to a winding position and removing a tray supporting an empty bobbin away from the winding position is provided with a tray holder for pressing down the tray located at the winding position.

Abstract: A twist number setting device for a two-for-one twister constituted such that an output power shaft of a drive motor is connected to a drive pulley which is connected to a spindle and provides a turning force to the spindle and also connected to a rotary shaft of a drum which contacts with a winding package and provides a turning force to the package, and a speed change mechanism is interposed between the output power shaft of the drive motor and the rotary shaft of the drum.

Abstract: A weft breaks monitoring system in a loom which examines the trend of the weft break, and comprises a device for measuring a winding diameter of a weft feed package and a tension meter for detecting a weft break, wherein the winding diameter is divided into plural sections and the number of times of weft break detections from the tension meter is counted every section. A yarn release device for the weft feed package which provides an adequate tension in response to a variation of a release tension resulting from a change in the winding diameter is also provided.

Abstract: In a system for producing yarns comprising a spinning apparatus having a plurality of spinning units, each unit being provided with a winding device, and a twisting machine directly connected to said spinning apparatus to twist a package from the spinning apparatus, a method comprises feeding packages of different kinds of yarns doffed from a group of units obtained by dividing units of the spinning apparatus to the twisting machine at different timing, and supplying them onto trays discriminated by kinds in the twisting machine.

Abstract: A method of untwisting sized yarn in a yarn splicing device, which comprises applying a solution to the ends of sized yarn to dissolve a size to thereby untwist the yarn at the ends thereof when they are joined together by a whirling stream of air.

Abstract: Shoyu, a liquid seasoning, has a blackish purple or blackish brown color, however, such color peculiar to the conventional shoyu is decolored and the shoyu is colored various colors such as red, blue, yellow, green, etc., whereby the conventional shoyu can be improved into one which is available in a variety of colors while maintaining the taste, aroma and flavor peculiar to the conventional shoyu.

Abstract: Method and Apparatus for forming a package including a steps of drafting and twisting a raw sliver to form a spun yarn, taking up at least two spun yarns in a paralleled state into the same package, and supplying the thus wound package directly to a two-for-one twister disposed in continuity with the spinning device.
