An apparatus for manufacturing a guitar string includes a table part; a holding part holds both ends of a first wire so that the first wire is rotatable; a winding part which is movable in a direction in which the first wire is extended, so that the winding part sequentially winds a second wire around on the outer surface of the first wire being rotated; and a supply part for supplying the second wire to the winding part, wherein the supply part includes a height measuring part; a first pulley part including a movable pulley and a movable body; a bobbin part around which the second wire has been wound; a motor part for rotating the bobbin part; and a control part which controls the speed of the second wire supplied to the winding part by controlling the operation of the motor part.

A method and a device for producing a twisted line comprising at least two wires. The at least two wires are unwound from at least one take-off spool and are twisted in a twisting unit to form the twisted line, wherein the twisting unit has a first roller and a second roller and the at least two wires are supplied to a twisting area between the two rollers and are twisted by turning the rollers in the same direction.

An apparatus for detwisting wires or cables wound in spools, includes two coaxial shafts, inserted one inside another and kinematically independent, of which a first shaft is connected to a first motor and is adapted to support, by rotating it about a rotation axis, one spool, and a second shaft is connected to second motor and supports, by rotating it about the rotation axis, a detwisting cage, which is adapted to rotate about the spool. The apparatus further includes at least one take up guide for the wire/cable, which is connected to a third motor in order to rotate about the rotation axis of the cage, oscillating toward the guide and/or away from it, and elements for coordination of the rotation speed of the first shaft with the rotation speed of the take up guide.

A power paying-off cradle consisting of power paying-off component and framework. In the framework is a cavity with an upper opening; a wire tension balance mechanism is installed in the cavity; a displacement wheel is installed on the wire tension balance mechanism, and a position detector of the displacement wheel is installed on the inner side wall of the framework; a turning wheel is installed on the front top of the framework; a thread hole is installed in the front of the framework; wire on the paying-off spool enwinds the turning wheel and the displacement wheel successively and passes through the thread hole. The wire tension balance mechanism has damping effect on the displacement wheel. When the tension of the displacement wheel is greater than or less than the damping force, the displacement wheel moves in order to ensure consistency of the tension or the strain of wire.

A stranding unit for a stranding machine has a stranding axis and a cage in which a number of baskets are arranged for receiving a number of reels having a strand material wound thereon. The stranding unit is characterized in that a stand is arranged which has a frame which extends around the cage in a circumferential direction around the stranding axis. The cage is mounted on the frame by a number of frame bearing elements and is rotatable around the stranding axis. As a result of the circumferential bearing, centrifugal forces are particularly efficiently distributed and absorbed by the frame during operation. In an advantageous further development, a plurality of basket are also mounted in a similar manner within the frame. The stranding unit as a whole is furthermore constructed such that it can be operated at a particularly high rotational speed.

A continuous stranding system is disclosed. According to an aspect of the present disclosure, a continuous stranding system including: a plurality of stranders configured to receive a center wire and a plurality of peripheral wires provided from outside to manufacture and discharge a strand in a shape of the plurality of peripheral wires stranded to a single layer around the center wire; and a winding spool configured to wind the manufactured strand into a shape of the peripheral wires stranded to multiple layers around the center wire by sequentially through the plurality of stranders may be provided. A first disposed strander among the plurality of stranders is configured to receive a wire from a supply spool of a plurality of wires as the center wire and the plurality of peripheral wires and other stranders among the plurality of stranders are configured to receive a strand discharged from a preceding strander as a center wire and a wire from the supply spool of a plurality of wires as a plurality of peripheral wires.
