The invention relates to a linear fibre formation comprising nanofibres deposited on a linear fibre core, at the same time the nanofibres are to the core fixed with a coil of at least one covering thread. The invention further relates to a method and a device for production of a linear fibre formation comprising a linear fibre core, on which in a spinning space of an electric field of high intensity the nanofibres produced through electrostatic spinning of polymer matrix are deposited. Through the spinning space of the electric field at least two straight segments of the linear fibre core are guided, between which the core outside the spinning space of electric field is guided at least along a section of circumference of the guiding cylinder, while in projection into a plane being tangential to circumference of the guiding cylinder and passing the respective segment of the core, this segment of the core and longitudinal axis of the guiding cylinder contain an acute angle.
