A traverser unit which performs the operation of winding on the bobbin in yarn transfer machines. The transverser unit includes: a traverser which ensures the yarns fed from the creel to be wound on the surface of the bobbin attached to the bobbin bearing on the machine body; a traverser bearing onto which the mentioned traverser is attached; a traverser shaft onto which the mentioned traverser bearing is attached to ensure traverser bearing's smooth movement along the horizontal direction; a traverser belt which is attached to the mentioned traverser bearing and allow the traverser bearing to perform lateral motion in the horizontal direction; a drive gear which deliver the required drive to the mentioned traverser belt, a multi-traverser apparatus includes at least two mentioned traversers and allows winding more than one yarn on the bobbin.

A winding apparatus includes a wire position support including first and second wire route hole in which first and second wires, respectively, are inserted, a winding driver that orbitally revolves the wire position support around a core of a coil component such that the first and second wires are wound around the core while twisted, a rotator that rotates the core, and a controller that controls the winding driver and the rotator. The controller performs first control, which orbitally revolves the wire position support in a first direction and rotates the core in an opposite second direction opposite, and second control, which orbitally revolves the wire position support in the second direction and rotates the core in the first direction, and switches between the first and second controls based on a predetermined condition, to prevent a kink of a wire between a wire feeder and a wire position support.

An elongated member pulling device including a support surface and a reel assembly for rotatably carrying a take-up reel about a first axis for receiving an elongated member, the reel assembly rotatably carried by the support surface about a second axis. A guide device including a plurality of rollers defining a closed geometry for guiding the elongated member toward the reel assembly. In response to the elongated member being guidingly received through the guide device and rotatably collected by the take-up reel, the reel assembly being selectably oscillatingly rotatable about the second axis to permit even winding of the elongated member on the take-up reel.

There is provided a wound thread package that is unlikely to cause problems such as cob-webbing and collapse at the time of unwinding even when the wound thread is a multi-filament thread or tape-like thread, and a manufacturing method for the same.

To manufacture a wound thread package 1 by winding a plurality of multi-filament threads or tape-like threads having a total fineness of 100 to 6400 dtex per thread around a bobbin 2 by a traverse method, the threads constituting a thread layer 3 are arranged at intervals therebetween and wound with the same in traverse width w and at different traverse reverse positions.

A winding apparatus for a coil component in which wires are wound around a core. The winding apparatus includes a wire position support including wire route holes in which the wires are inserted, a wire feeder that feeds the wires to the wire position support such that tension is applied to the wires, a winding driver that orbitally revolves the wire position support around the core such that the wires are wound around the core while twisted, a rotator that rotates the core, and a controller that controls the winding driver and the rotator. The controller controls a rotation direction of the core with regard to an orbital revolution direction of the wire position support and an orbital revolution speed of the wire position support to prevent generation of a kink of a wire between a wire feeder and the wire position support.

Various embodiments of the present disclosure provide a rotorcraft-assisted system and method for launching and retrieving a fixed-wing aircraft into and from free flight. The launch and retrieval system includes a modular multicopter, a storage and launch system, an anchor system, a flexible capture member, and an aircraft-landing structure. The multicopter is attachable to the fixed-wing aircraft to facilitate launching the fixed-wing aircraft into free, wing-borne flight. The storage and launch system is usable to store the multicopter (when disassembled) and to act as a launch mount for the fixed-wing aircraft by retaining the fixed-wing aircraft in a desired launch orientation. The anchor system is usable with the multicopter, the flexible capture member, and the aircraft-landing structure to retrieve the fixed-wing aircraft from free, wing-borne flight.
