Abstract: The invention relates to a linear fibrous formation with a coating of polymeric nanofibers consisting of a core formed by a supporting linear formation (3) and polymeric nanofibers. The polymeric nanofibers envelop the supporting linear formation (3) constituting a core (31) of the resulting linear fibrous formation (30) with a nanofibrous coating (32) composed of a flat formation created from a nanofibrous plume (6) with an organized structure of nanofibers generated by electro spinning using AC high electric voltage, whereby the nanofibrous coating (32) is wrapped around the core (31) with a helical-shaped stripe. In addition, the invention relates to a method for the production of a linear fibrous formation with a nanofibrous coating containing polymeric nanofibers, whose core is composed of a supporting linear formation (3). On a spinning electrode (5) powered by AC voltage is formed a nanofibrous plume (6), which in the spinning space (41) changes into a flat stripe with an organized structure of nanofibers, which is fed towards the circumference of the supporting linear formation (3) rotating in the spinning space around its own axis and/ or ballooning in the spinning space with at least one anti-node loop, whereby the stripe created from the nanofibrous plume (6) winds around the supporting linear formation, forming a helix around the supporting linear formation (3). The invention also relates to a device for producing a linear fibrous formation.
