A bundling device comprises a frame, and a wire bending device and a wire twisting device each mounted to the frame. The wire bending device bends a bundling wire into an open ring to partially surround an object to be bundled, and guide the bundling wire into the wire twisting device. The wire twisting device twists two opposite end segments of the bundling wire together to bundle the object.

A method of twisting a pair of wires includes the steps of arranging a first wire parallel to a second wire along a longitudinal axis, securing ends of the first and second wires, and gripping outer surfaces of central portions of the first and second wires. Inner surfaces of the central portions of the first and second wires are in contact with one another. The method further includes the step of rotating the central portions of the first and second wires, thereby twisting the first and second wires about one another.

An electric wire twisting device is provided, which is capable of producing a preferable twisted electric wire from a plurality of electric wires of which both ends are cut. An electric wire twisting device 1 includes a first gripping device 11 including a first clamp 2a that grips a first end of a first electric wire CT, a second clamp 2b that grips a first end of a second electric wire C2, and a first holder 15A that holds the first clamp 2a and the second clamp 2b. The electric wire twisting device 1 includes a second gripping device 12 that grips a second end of the first electric wire CT and a second end of the second electric wire CT, a first revolving actuator 3b that causes the first holder 15A to rotate around a center line of revolution CL, and a first rotating actuator 3a that causes the first clamp 2a and the second clamp 2b to rotate around a center line of rotation that is parallel to the center line of revolution CL or is inclined with respect to the center line of revolution CL.

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.

A device and a method twist single cables about a twisting axis to form a cable bundle along an extension axis. The device includes single rotating units, which are spaced from one another at a variable distance, for separately holding cable ends at one end of the single cables, wherein each single rotating unit is mounted rotatably about an associated pivot axis, wherein each pivot axis runs substantially perpendicular to the extension axis of the cable bundle; a twisting unit for holding and twisting cable ends at the other end of the single cables; and a distance-adjusting apparatus for adjusting the variable distance.

A device and a method twist single cables about a twisting axis to form a cable bundle along an extension axis. The device includes mutually spaced single rotating units for separately holding cable ends at one end of the single cables; a twisting unit for holding and twisting cable ends at the other end; and a guiding apparatus, to which is fastened a guiding mandrel for separating the single cables, at least in some regions, during a twisting process by the twisting unit, in a transition region from an untwisted region to a twisted region. The guiding apparatus further includes: a movement element for moving the guiding mandrel out of an initial position into a moved-in position, in which the guiding mandrel is moved into the twisting axis; and a locking element for holding the guiding mandrel in the position moved in out of the twisting axis.
