Abstract: A yarn end finding apparatus having a vertically movable hollow member which can be raised to allow positioning of a bobbin thereunder and then lowered onto the bobbin. The hollow member includes a device for releasing the end of the yarn from the bobbin. A vertical flow of air through the hollow member directs the released yarn away from the bobbin past a yarn clamping device and a blade which cuts the yarn at a predetermined distance from the clamping device. A reverse flow of air directs the remaining length of yarn into the hollow bobbin core for subsequent processing.

The cops are transported along a cop feeding line extended between a spinning frame and winding units of the winder being carried on carriers respectively. The yarn readying device includes a cop hanging mechanism and a yarn end readying mechanism for unwinding and cutting a starting end of the cop, cutting a tangled yarns and inserting the starting yarn end into a bore of a bobbin of the cop.

Abstract: A bobbin supplying system for use with an automatic winder. A spinning bobbin is erectly fitted on a transporting medium and is circulated between winding units and a bobbin supplying station. In response to arrival of the transporting medium at the bobbin supplying station, a bobbin demanding signal is produced in order to supply a spinning bobbin to the empty transporting medium.

Abstract: Fly waste removing system for the spinning winder which has a spinning frame and a winder connected to each other. A common cleaner having ducts is run between a spinner area and a winder area to blow off or suck the fly wastes by applying air from air injection and/or air suction ports of the ducts.

Abstract: A spinning frame is connected to the winder through a delivery passage comprising conveyor belts, rotary disc and the like to form a closed loop. Cops are inserted independently on trays arranged on the delivery passage and are circulated along said closed loop in the state where they are vertically inserted. When the residual yarn-retaining bobbin is detected, the bobbin is re-circulated after required processes such as a pick finding operation.

Abstract: A cop transporting system for an automatic winder in which a single automatic winder can wind a plurality of different kinds of yarn at a time. A winder including a number of winding units therein is divided into a plurality of sections each including a plurality of winding units therein as a group, each of the sections having a specific cop supplying passage provided therein along the winding units. Each of the sections have a cop supply device provided therefor and cops fed out from the cop supply devices are transported to the specific supplying passage of the sections corresponding to the cop supply devices.

Abstract: The number of yarn knots while a package is being wound is detected and stored, and compared with a preset number of yarn knots for a single package. When the stored number of yarn knots is greater than the preset number, a signal is produced which is indicative of a defective package. The defective package is sorted out and discharged on a conveyor by a processing unit under the control of the produced signal.

Abstract: A pneumatic yarn splicing method and apparatus for spun yarns. Extremities of ends of the yarn which are inserted in overlapping and oppositely directed relationship in a yarn splicing hole are in free conditions and at least two different points of the yarn ends within the splicing hole are individually acted upon by flows of a fluid turning in opposite directions.

Abstract: A structure of a joint of spun yarns formed by lapping the tops of two yarn ends in the untwisted state and jetting a compressed fluid to the lapped portion while keeping the tops of the yarn ends free without securing the tops of the yarn ends. In at least one portion of the joint, fibers of the two yarn ends are integrated to form one yarn having twists of the same or opposite twisting direction as or to the twisting direction of inherent twists of the spun yarn.

Abstract: A pneumatic yarn splicing device comprises a bracket, a yarn splicing member mounted on the bracket and having a pair of side faces and a yarn splicing hole extending transversely between the side faces, the yarn splicing member including an air ejection nozzle for ejecting a compressed air flow into the yarn splicing hole, and a pair of yarn presser levers pivotably mounted with respect to the bracket and each having on a distal end thereof a step defined by a first portion close to one of the side faces and a second portion spaced therefrom, the yarn splicing hole being partly closable by the first portion when the yarn presser levers are angularly moved to bring the step into confronting relation to the yarn splicing hole.

Abstract: A splicing apparatus for spun yarns comprises a splicing member which has a cylindrical splicing hole, a slit for insertion of the yarns and a jet nozzle jetting a compressed fluid and opened to the splicing hole in the tangential directions, and yarn end control nozzles, yarn cutting devices, a yarn guiding means and yarn clamping devices, which are arranged in sequence on both sides of the splicing member. Control plates for covering the opening of the splicing hole partially is arranged on both the sides of the splicing member to control the quantity of the fluid flowed out from the opening of the splicing hole.

Abstract: Carbon black is produced from sources of acetylene and at least one gaseous hydrocarbon selected from the group consisting of ethylenically unsaturated hydrocarbons, aromatic unsaturated hydrocarbons, monocyclic unsaturated hydrocarbons and polycyclic unsaturated hydrocarbons and oxygen. A thermal decomposition of acetylene and a partial combustion-reaction of hydrocarbon independently perform at a moment at the initiation of the reaction; and then, performing mixed reactions of all sources for the reactions in the same region in a reaction furnace.

Abstract: A cop supplying truck which runs along the individual winding units of an automatic winding machine is provided. The cop supplying truck travels while storing the cops accomodated in an individual cylindrical cop container and feeds the cops into a magazine of a winding unit without stopping at the individual winding units. The cop supplying truck is provided with a hole through which the cop falls onto the magazine. The cops are travelled and fed by means of a first conveyer device which works to successively convey the cop containers toward the falling hole, a device which takes one of the cop container while the cop supplying truck passes over the empty magazine, and a second conveyer device which so works that a cop in the taken-out cop container is only allowed to fall into the magazine through the falling hole.

Abstract: This apparatus is used for splicing the ends of the spun yarn by inserting the yarn ends into an air jet nozzle having one or a plurality of air jet pipes, in which they are doubled and subjected to an air jet to join each other. Yarn end cutting and holding devices for the top yarn and the bottom yarn are disposed at the both ends of a yarn inserting hole of the air jet nozzle. An automatic yarn inserting device may be provided with the apparatus to introduce the yarn ends into the yarn inserting hole and into the yarn end cutting and holding devices.

Abstract: Broken ends of a spun yarn are introduced into a hole of an air nozzle device from upper end and lower end of the hole respectively and the yarns are doubled. The doubled yarns are slightly slacked and subjected to air jetting by the air nozzle device to produce a spliced joint. The distribution of twists inherent of spun yarns is changed in the region of the spliced joint by twists imparted to the yarns by the air jet nozzle and at least one fixed portion of the new twist distribution is formed in the spliced joint.
