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.

Provided herein is a multi-core cable through which positions of a plurality of insulated conductors and a plurality of non-insulated conductors in a cross section in a longitudinal direction are changed and a likelihood of transmission performance being reduced is low. A multi-core cable includes n conductor bundles.

Apparatus for robot motion control and wire dispensing during automated routing of wires onto harness form boards. The robot includes a manipulator arm and a wire-routing end effector mounted to a distal end of the manipulator arm. The wire-routing end effector is configured for dispensing and routing a wire along a path through form board devices mounted to a harness form board. The wire-routing end effector is moved along a planned path under the control of a robot controller. An end effector path is provided with a set of processes that enable rapid, even fully automatic, development of robot motion controls for routing wires on harness form boards. The system uses a measurement encoder on the end effector that is routing individual wires on a wire harness form board to learn the length of each wire and its length variation.

A wire stranding apparatus, comprising: a core wire moving mechanism configured to move a core wire in an axial direction; a spool configured to feed a wound wire by rotation; a revolving mechanism configured to revolve the spool about the core wire; a rotation driving mechanism configured to feed the wire by rotating the spool, the wire fed from the spool being spirally wound on an outer periphery of the core wire moving in the axial direction by revolution of the spool; and a control device including a wire speed obtaining unit configured to obtain a speed of the wire to be wound on the core wire and a rotation driving mechanism control unit configured to control the rotation driving mechanism such that the speed of the wire obtained by the wire speed obtaining unit has a predetermined value.

Aspects of the disclosure relate to methods of forming and using hybrid wirelines, and associated apparatus thereof. The method is configured to form a hybrid wireline cable that comprises a core having a conductive strand and an insulation layer disposed around the conductive strand. A first plurality of solid wires are disposed around the core to form an inner armor layer. A combination of a first plurality of stranded wires and a second plurality of solid wires are disposed around the inner armor layer to form an outer armor layer. A jacket is disposed around the inner armor layer and the outer armor layer.
