A coiled product, a control installation, computer software product, a coiling machine and method for coiling a coiled product, wherein the coiling tension is settable to an envisaged coiling tension, particularly to a constant coiling tension via either a setting unit and/or a change in the respective rotational speed of either a coil body and/or a supply roll, a characterizing aspect being the equalization of the free length of the coiled product, where the free length is the spacing of the first bearing point of the coiled product on the coil body from the second bearing point of the coiled product on a deflection roller such that the free length change is equalized by the setting unit and/or by a variation of the respective rotational speed so that coiling tension of a product coiled onto the coil body can be set in a simple, rapid, and precise manner.

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.

A method for manufacturing a coil component that can contribute to prevention of durability degradation of a wire. The method includes winding a plurality of wires, that are supplied from a wire supply source to a nozzle through a tensioner, around a core by revolving the core around the nozzle. Also, during the winding, the core is rotated in a direction same as or opposite to a revolution direction of the core.
