CABLE AND METHOD FOR MONITORING A CABLE

Cabin Air Group B.V., Jo...

1. A cable (1), comprising:
a first thimble (2) and a second thimble (4), at least one yarn (6), and at least a first conductive fibre (8) for monitoring the cable (1), wherein

the first thimble (2) and the second thimble (4) are provided at opposite ends of the cable (1),

the at least one yarn (6) extends from the first thimble (2) to the second thimble (4), turns around the second thimble (4), extends from the second thimble (4) to the first thimble (2), and turns around the first thimble (2), such that

the at least one yarn (6) forms a turn around the first and second thimbles (2, 4), and

each thimble (2, 4) holds a stack (9) of layers (10) of turns of the at least one yarn (6), wherein an inside of the stack (12) is defined as a side of a first layer of turns of the at least one yarn (6) being closest to a centre (14) of the respective thimble, an outside of the stack (16) is defined as a side of a last layer of turns of the at least one yarn (6) being farthest away of the centre (14) of the respective thimble, and a stack height (h) is defined as the distance from the inside of the stack (12) to the outside of the stack (16), wherein,

the cable (1) comprises a plurality of conductive fibres (8, 18, 108, 118), which conductive fibres (8, 18, 108, 118) are different from the at least one yarn (6), wherein at least two of the plurality of conductive fibres (8, 108) are positioned in the stack (9) of layers (10) of the first thimble (2) between the turns of the at least one yarn (6) at a first predetermined height (h1) measured from the inside of the stack (12), spaced apart from each other in a width direction of the first thimble (2), wherein the first predetermined height (h1) is less than 50% of the stack height (h).

the first conductive fibre (8) is different from the at least one yarn and designed to signal the wear of the at least one yarn (6) by breaking after a predetermined portion of the turns of the at least one yarn (6) breaks,

the first conductive fibre (8) is positioned in the stack (9) of layers (10) of the first thimble (2) between the turns of the at least one yarn (6) at a first, predetermined height (h1) of the stack measured from the inside of the stack (12), and

the first predetermined height (h1) is less than 50% of the stack height (h).

DEVICE AND METHOD FOR PRODUCING A LOAD BEARING CABLE, AS WELL AS A LOAD BEARING CABLE

Cabin Air Group B.V., Jo...

1. A device for producing an endless winding cable by winding at least one yarn around two thimbles that are provided at opposite ends of the cable, comprising:an elongated guide and a carriage movably connected to one another for a movement of the carriage relative to the elongated guide in a length direction of the elongated guide;
a first thimble holder and a second thimble holder connected to the elongated guide at a distance from one another, with each thimble holder designed to hold one of the two thimbles;
a yarn feeder connected to the carriage, said yarn feeder comprising at least one spool holder for holding a spool with the at least one yarn, and an output guide for guiding the at least one yarn to the cable during winding;
wherein the output guide and the first thimble holder, as well as the output guide and the second thimble holder, are movable relative to each other in at least a direction perpendicular to the length direction of the elongated guide for guiding the at least one yarn half a turnaround respectively the first one of the two thimbles and the second one of the two thimbles during winding; and
wherein the yarn feeder comprises at least one yarn brake for controlling a tension of the at least one yarn while being fed into each yarn layer during winding, further comprising a control, wherein the at least one yarn brake is controllable by the control, and wherein the control is configured to increase tension during winding, such that tension of at least one subsequent yarn layer is greater while winding the at least one subsequent yarn layer than is tension of previous layers of yarn turns.
