A coil winding machine is adapted for winding a conductive flat wire onto an iron core. The coil winding machine includes a base, a tension mechanism mounted on the base and adapted for delivering the flat wire and providing tension to the flat wire, a rotary mechanism mounted on the base and including a core base that is rotatable and that is adapted to be mounted with the iron core, and at least one clamping mechanism mounted on the base, being co-rotatable with the core base, and operable for abutting the flat wire tightly against the iron core. A tension provided by the tension mechanism, a pressure provided by the clamping mechanism, and a rotational speed of the core base correspond to one another such that rotation of the core base and the at least one clamping mechanism winds the flat wire onto the iron core.

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.

The invention relates to a device and to a method for winding toroidal cores without using a magazine, comprising a toroidal-core retainer and comprising elements that are substantially arranged in a wire-guiding plane and that serve to guide and to magazine wire. The device comprises: a first transport roller and a second transport roller, which are arranged in relation to the toroidal-core retainer in such a way that a wire to be magazined on the transport rollers in the wire-guiding plane and to be wound can be guided between the first and the second transport roller through the toroidal core; a wire ejector arranged adjacently to the second transport roller; and a wire tensioner.
