摘要:
A cable / sling / endless rope (1) comprises 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). The 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). Each thimble holds a stack (9) of layers (10) of turns of the yarn (6). The first conductive fibre (8) is designed to signal the wear of the yarn (6) by breaking after a predetermined portion of the turns of the yarn (6) breaks. The first conductive fibre (8) is positioned at the first thimble (2) between the turns of the yarn (6) at less than 50% of the stack height h.

A cable comprises a first and a second thimble (2, 4), and at least one main yarn (6) and an auxiliary yarn (7). The first and the second thimble are provided at opposite ends of the cable. The at least one main yarn (6) and the auxiliary yarn (7) each forms turns around the first and second thimble (2, 4). Each thimble (2, 4) comprises a bearing surface (40), and holds a stack (19) of layers (10) of turns of the main yarn (6). A stack (119) of turns of the auxiliary yarn (7) comprising at least a first layer (13) of turns of the auxiliary yarn (7) lies on the bearing surface (40) of the respective thimble (2, 4).

摘要:
A device (100) produces an endless winding cable (101) by winding a yarn (106) around two thimbles (102, 104). The device (100) comprises an elongated guide (110), a carriage (112), a yarn feeder (114), a first thimble holder (116), and a second thimble holder (118). The first thimble holder (116) and the second thimble holder (118) each hold one of the two thimbles (102, 104). The carriage (112) is movable relative to the elongated guide (110). The yarn feeder (114) is connected to the carriage (112), and comprises at least one spool holder (120) for holding a spool (122) with the at least one yarn (106), and an output guide (124) for guiding the at least one yarn (106) to the cable during winding. The yarn feeder (114) comprises at least one controllable yarn brake (126) for changing a tension of the at least one yarn (106) during winding. Moreover, a corresponding method and an endless winding cable (101) with increasing tension from a more inner layer of said winding yarn (106) to a more outer layer of said winding yarn (106) when seen from a respective thimble (102, 104) is disclosed
