Abstract
Official abstract text for this publication.
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 of the single cables; 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 region in which there is a transition from an untwisted region to a twisted region. The guiding mandrel includes a thickened portion on a side opposite its fastening to the guiding apparatus, the thickened portion having larger dimensions in a direction transverse to the running direction of the guiding mandrel than in most of the guiding mandrel.
First claim

What is claimed is: 1. A device ( 100 ) for twisting single cables ( 11 , 12 ) about a twisting axis (V) to form a cable bundle ( 10 ) along an extension axis (A), the device comprising: mutually spaced single rotating units ( 41 , 42 ) for separately holding cable ends ( 15 , 16 ) at one end of the single cables ( 11 , 12 ); a twisting unit ( 30 ) for holding and twisting cable ends at the other end of the single cables ( 11 , 12 ); and a guiding apparatus ( 35 ) fastened to a guiding mandrel ( 360 ) for separating the single cables ( 11 , 12 ), at least in some regions, during a twisting process by means of the twisting unit, in a region in which there is a transition from an untwisted region to a twisted region, wherein the guiding mandrel ( 360 ) has a thickened portion ( 361 ) on a side opposite its fastening to the guiding apparatus ( 35 ), said thickened portion having larger dimensions in a direction transverse to the running direction of the guiding mandrel ( 360 ) than in most of the guiding mandrel ( 360 ). 2. The device ( 100 ) according to claim 1 , wherein the thickened portion ( 361 ) is configured to limit an oscillating movement during the twisting process. 3. The device ( 100 ) according to claim 1 , wherein the guiding mandrel ( 360 ) has a substantially circular cross-section, at least in some regions, and wherein the guiding mandrel ( 360 ) has a larger diameter in the region of the thickened portion ( 361 ) than in most of the guiding mandrel ( 360 ). 4. The device ( 100 ) according to claim 1 , wherein the thickened portion ( 361 ) is formed on the end of the guiding mandrel opposite the fastening to the guiding apparatus ( 35 ). 5. The device ( 100 ) according to claim 1 , wherein the guiding mandrel ( 360 ) has a widened portion in the direction of the fastening to the guiding apparatus ( 35 ), so that a guiding region ( 362 ) for the single cables ( 11 , 12 ) is formed between the widened portion and the thickened portion ( 361 ). 6. A method for twisting single cables ( 11 , 12 ) about a twisting axis (V) to form a cable bundle ( 10 ) along an extension axis (A), the device ( 100 ) according to claim 1 being used to carry out the method, the method comprising: separately holding cable ends ( 15 , 16 ) at one end of the single cables ( 11 , 12 ) by means of the single rotating units ( 41 , 42 ); holding cable ends at the other end of the single cables ( 11 , 12 ) by means of the twisting unit ( 30 ); rotating the twisting unit ( 30 ) to carry out a twisting process; and limiting an oscillating movement during the twisting process by means of the thickened portion ( 361 ) of the guiding mandrel ( 360 ).
