A dual cable alignment apparatus (10) for rotationally aligning assembled cable ends of two cables (3,4) of a twisted cable harness (2), the cable alignment apparatus (10) comprising two clamping jaws (7,8) and a central web (9) disposed between the clamping jaws (7,8). Each of the two clamping jaws (7,8), which can be moved towards one another in the closing direction (s), can clamp a cable (3,4) between the central web (9) and the clamping jaws (7,8). The clamping jaws (7,8) are further designed to be movable laterally past the central web (9) for changing the rotational position by rolling the cable (3,4) clamped between them. The clamping jaws (7,8) can be moved independently of one another in the lateral direction by means of their own lateral drives (16,17), ensuring that each cable (3,4) can be brought precisely and reliably into the desired rotational position.

A magnetic detector includes permanent magnets that magnetize a wire rope W in the longitudinal direction, and a search coil that detects a change in the cross sectional area of the wire rope W magnetized by the permanent magnets. The magnetic detector is provided so as to surround a part of the wire rope W. Prior to inspection, the magnetic detector is moved back and forth at least three times across an inspection range of the wire rope W. After the magnetic detector is moved back and forth, the change in the cross sectional area, that is, damage to the wire rope W is inspected by using signals outputted from the search coil.

A forming device for forming links in the shape of a Möbius strip includes a rotation module with an inner path. The forming device has a widening for 180° rotation of a strip introduced into the rotation module. The rotation module has an inlet suitable for one end of a strip, an outlet suitable for the strip and the inner path extends from the inlet to the outlet. The widening is adapted for rotation of the end of the strip 180° about its longitudinal axis. The device also includes a gas injector positioned at the inlet of the rotation module intended to drive the strip through the inner path of the rotation module.

A round sling system comprises a bearing structure, a cover, and at least one organizer secured to the cover. The bearing structure is arranged to define a plurality of loop portions and to define at least one bearing structure end portion. The cover defines a cover chamber. The at least one organizer is configured to engage the bearing structure such that the at least one organizer maintains a position of the bearing structure relative to the cover and the at least one organizer maintains a spatial relationship of the loop portions at least within the at least one bearing structure end portion.

A spliced rope apparatus and a method of forming the same are disclosed. The apparatus has a first rope including a first plurality of strands and a second rope including a second plurality of strands. The apparatus also has a splice connecting the ropes and defined by the first and second pluralities of strands. The splice has a spiral section including a first pair having strands of the first plurality of strands that are positioned proximate each other. The first pair extends helically and the strands of the first pair together pass under a plurality of picks defined by the second plurality of strands and together pass over a remainder of the second plurality of strands. The splice also has a tuck section in which at least some of the first plurality of strands extend longitudinally to pass under and over sequential picks defined by the second plurality of strands.

The present invention relates to synthetic cables comprising core and splicing threads with high modulus threads, wherein the ends of the cable comprise looped or eyelet splice-type termination ends (1), and wherein each leg of the parallel splicing threads (13, 13′) is connected to parallel core threads (21) at an interpenetration region (12). The method comprises individually connecting each leg of the splicing threads (13) with a positive splice to a core thread(s) (21) of the beginning end of the cable (2); looping; straining all the threads and applying a normal compression force at the interpenetration region (12); applying a protective element(s) (32) along the cable and further individually connecting each leg of the splicing threads (21) to form a negative splice to a core thread(s) (21) of the final end of the cable core (2); and looping, straining and applying a normal compression force (12) on the negative splice at the interpenetration region.

The invention relates to an endless shaped article comprising at least one strip of material forming a plurality of convolutions of the strip of material, the strip having a longitudinal axis, wherein each convolution of said strip comprises a twist along the longitudinal axis of said strip, wherein said twist is an odd multiple of 180 degrees. The invention also relates to a method to manufacture said article, and its use as sling, loop, belt or chain link.

The present invention discloses an encapsulated duct cable with identification tags and a manufacturing method thereof. The logging encapsulated duct cable comprises an encapsulation layer. The cross section of the encapsulation layer is polygonal or arc-shaped. At least one cable protective tube and at least one oil-liquid tube are arranged in the encapsulation layer. A cable is arranged in the cable protective tube. Identification tags with different color identifiers are respectively arranged on one side of the cable protective tube and one side of the oil-liquid tube in one to one correspondence. The manufacturing method of the logging encapsulated duct cable mainly comprises three steps of machining the cable protective tube and paving the cable pavement, machining the oil-liquid tube, and machining the encapsulation layer.
