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.

Disclosed are a medicated thread manufacturing system and medicated thread manufacturing method. The medicated thread manufacturing system includes a first slideway and a second slideway, a thread clamping apparatus and a medicine spraying apparatus that are slidably arranged on the first slideway, and a thread winding apparatus slidably arranged on the second slideway. The thread clamping apparatus is used for clamping two ends of a to-be-processed medicated thread, straightening the to-be-processed medicated thread and twisting the to-be-processed medicated thread in the straightened state into a single-strand rope state. The medicine spraying apparatus is used for spraying a medicine towards a surface layer of the to-be-processed medicated thread in the straightened state. The thread winding apparatus is used for abutting a center position of the to-be-processed medicated thread in the single-strand rope state and pulling the to-be-processed medicated thread towards a direction opposite to the first slideway to fold the to-be-processed medicated thread, and used for rotating the to-be-processed medicated thread, such that the to-be-processed medicated thread winds and extends from middle to two ends to be twisted in a double-strand rope state. The control apparatus controls a matching opportunity of the thread clamping apparatus, the medicine spraying apparatus and the thread winding apparatus. Artificial participation is not needed in the manufacturing process of the medicated thread, such that automation of manufacturing the medicated thread is realized.

A medicated thread manufacturing system and associated method includes first and second slideways, a thread clamping apparatus and a medicine spraying apparatus slidably arranged on the first slideway, and a thread winding apparatus slidably arranged on the second slideway. The clamping apparatus clamps two ends of a to-be-processed medicated thread, straightens the thread and twists the thread in the straightened state into a single-strand rope state. The spraying apparatus sprays a medicine towards a surface layer of the thread in the straightened state. The winding apparatus abuts a center position of the thread in the single-strand rope state, pulls and folds the thread, and rotates the thread such that the thread winds and extends from middle to two ends to be twisted in a double-strand rope state. A control apparatus is in signal connection and/or electrical connection to the clamping apparatus, the spraying apparatus and the winding apparatus.

A cable-stranding apparatus includes a stationary guide, a motor, a driven guide, and a controller electrically coupled to the motor. The stationary guide is configured to guide strand elements in a spaced-apart configuration and to pass a core member. The motor is operatively associated with a guide driver. The driven guide is disposed at least partially within the guide driver so as to rotate therewith. The driven guide is configured to receive the strand elements from the stationary guide, individually guide the strand elements received from the stationary guide, and to further pass the core member. The controller is electrically coupled to the motor and configured to control the rotational speed and direction of the motor.

A twisted wire manufacturing method for manufacturing a twisted wire, includes hanging U-turn portions of the at least two wires on a wire hanging member, checking one end portions and the other end portions of the at least two wires, pulling up the at least two wires in a state that the U-turn portions are hung on the wire hanging member, twisting the at least two wires together after the wire pull-up step is conducted, and transferring a twist-completed wire produced by the wire twisting step to a twisted wire temporary placement hook which is disposed above the wire hanging member.

The present disclosure relates to a twisting system for twisting multiple conductors together. In one implementation, the twisting system may include a rotatable twisting head having multiple holders for individual conductors of a cable to be twisted, and a loading device for sequentially loading the holders with the individual conductors. The loading device may be configured to be displaced into a transfer position identical for all individual conductors for loading the twisting head, and the twisting head may be configured to rotate a free holder of the twisting head into a suitable receiving position for being loaded with an individual conductor. The present disclosure also relates to a method for loading a twisting head with individual conductors.

The cable coiling device automatically coils heavy-duty electrical cable into a coiled bundle having a predetermined coil diameter. This device matches the over/under coiling method used to manually coil cables that eliminate unnecessary twists and knots in cables. The cable coiling device has a first roller and a second roller that is angularly offset from the first roller. The angular offset adds a twist to the cable as it passes between the rollers. The device maintains the first and second rollers at a predetermined distance away from each other so that the cable does not slip out of the opening between the rollers. When the coil exits the rollers, the resulting cable is coil bundled and has a specific predetermined coil bundle diameter. Guide wheels positioned at specific locations guide the cable through the device, which prevents cable looping before and after the cable passes through the rollers.

The present invention relates to synthetic cables comprising core and splicing threads with high modulus threads, wherein the ends of the cable comprise looped or eyelet splice-type termination ends (1), and wherein each leg of the parallel splicing threads (13, 13′) is connected to parallel core threads (21) at an interpenetration region (12). The method comprises individually connecting each leg of the splicing threads (13) with a positive splice to a core thread(s) (21) of the beginning end of the cable (2); looping; straining all the threads and applying a normal compression force at the interpenetration region (12); applying a protective element(s) (32) along the cable and further individually connecting each leg of the splicing threads (21) to form a negative splice to a core thread(s) (21) of the final end of the cable core (2); and looping, straining and applying a normal compression force (12) on the negative splice at the interpenetration region.
