Abstract: A winding apparatus includes a first rotation body, and a wire position support, inserted in an insertion hole outside a center axis of the first rotation body, and including first and second wire route holes in which first and second wires are inserted, respectively. The winding apparatus further includes a second rotation body having a center axis and separated from the first rotation body, a shaft body outside the center axis, a synchronous rotation component coupling the wire position support and the shaft body while unrotatably fixed to the wire position support, a winding driver that synchronously rotates the first and second rotation bodies, and inner bearings disposed between the wire position support in the insertion hole and the first rotation body, in which the wire position support is journaled with respect to the first rotation body. Thus, the wire position support revolves orbitally about a core without rotating.

Abstract: An elastic composite twisted yarn includes a covered elastic yarn, having a core yarn formed of an elastic yarn and a sheath yarn formed of a thermoplastic multi filament, and first and second low stretch yarns formed of a thermoplastic multi-filament yarn or a spun yarn. The covered elastic yarn is drawn at a predetermined draw ratio to be inserted into the first low stretch yarn in a combined yarn state. The yarn in the combined yarn state and the second low stretch yarn are combined and twisted to obtain an elastic composite twisted yarn. A plurality of heteromorphic micro-loops formed of a constituent single fiber of the sheath yarn, which appears during the relaxation by a contractile force of the covered elastic yarn, protruding from the core yarn to a diameter direction, is usually incorporated into a constituent single fiber of the first low stretch yarn and thermally set.

Abstract: A process and apparatus are disclosed for making a hybrid cord which may be used. The process combines and twists at least three yarns together where one of the yarns is different. The different yarn maybe of a different size (denier), or made from a different polymer, or both. The hybrid cord may be used in tires, hoses, v-belts, and conveyor belts, for example. The apparatus is a modified direct cabler machine in which at least two yarns from a creel are combined and twisted about a third yarn issuing from a spindle pot. It is contemplated that the different yarn is preferably one of the yarns on the creel. Various tensioners are employed to tightly wrap or twist the yarns together (generally at a rate of from about 5-12 turns per linear inch of the yarn issuing from the spindle pot), and to wind the cord on a bobbin.

Abstract: The invention includes a first bobbin that supplies a first yarn, a second bobbin that supplies a second yarn, and a third bobbin that supplies a third yarn. Additionally, the invention includes a guide that guides the first and second yarns so that they are substantially parallel to each other, and a combining device the combines and twists the parallel disposed first and second yarns with the third yarn. The invention enables the manufacture of a two-ply cord having a filler yarn therein, in a single step, and also allows more cord to be manufactured within a specified time period.

Abstract: A method and a device for facilitating the sliding, along a track, of an element having a predominant axial dimension subjected to an intense force pressing it against the track, particularly for facilitating the sliding of a wire subjected to stranding in stranding machines. The method consists in interposing between the element and the track a pressurized fluid which contrasts the force that presses the element against the track. In this way, the sliding friction of the element on the track is reduced and it is possible to reduce the force to be applied to the element in order to achieve its advancement along the track.
