The method according to claim 10 or 15, The power transmission means, A plurality of transfer holes in which a plurality of transfer grooves are recessed to insert the support mechanism of the carrier; A plurality of transfer gears for applying a rotational force to rotate the respective transfer holes; And Braiding device of the braid having a multi-layer structure, characterized in that it comprises an electric gear meshed with any one of the transfer gear. The method according to any one of claims 10 to 16, The basic braiding unit, And an auxiliary trajectory formed on the outer surface of the basic braid layer to cross at least one braided cable along a longitudinal direction to form the braided cable so as to cross the track forming the basic braided layer. Braided device having a multi-layer structure, characterized in that the carrier having a carrier for supplying the braid for the formation of the braided cable, the transfer port for driving the carrier, and the transfer gear. The method of claim 18, It is provided with a core wire supply unit to supply a core wire to the inside of the basic braided layer on the lower side of the basic braided portion, The auxiliary trajectory is formed on the left and right sides of the guide plate to form a pair of the braided cable on the outer peripheral surface of the basic braided layer, Braiding device having a multi-layer structure, characterized in that the additional braiding portion is configured on the upper side of the basic braiding portion to be braided on the outer circumferential surface of the basic braiding layer including the braided cable.
