Method of forming a rigid rod on an end of a tension member
A tension member has fibres straightened such that they are substantially parallel. The fibres are then held in the base of mould. A curable resin such as castable synthetic polymer resin, is applied around the fibres. The side of mould is then placed on base trapping compression tool as part of the mould. The cylindrical cavity defined by the mould is filled with curable resin, The curable resin is then allowed to set, and the mould removed to form a rigid rod on the end of the tension member.
Steel cord and manufacturing process therefor
A steel cord and a manufacturing process are disclosed. The steel cord includes a steel core wire located in the center and having a diameter of d; and M sheath-layer steel wires arranged around the steel core wire in the center, tangent to the steel core wire, and having a diameter of d1, at least two gaps L existing between the M sheath-layer steel wires, where M is 4; d, d1, and L satisfy the following relationship: 0.420<(d/d1)<0.800, d1 is between 0.20 mm and 0.44 mm, and L0.0008 mm. The steel cord of the present invention may allow rubber to be fully penetrated into the gaps, thereby reducing air content in the steel cord, avoiding point contact friction between the layers of steel wires due to insufficient rubber penetration, and further solving the problem of failure of the bearing capacity of the steel cord due to abrasion.
Rope End-Fastening Method, Rope with End Fastener, and End Fitting for Use in Rope End-Fastening Method
A rope terminal fixing method is provided, which may be used easily at a construction site, causes less shearing load, and may reliably prevent the falling-off of the rope.
The rope terminal fixing method comprises the following steps. A tubular terminal metal fitting which comprises a proximal opening, a distal opening, and a through hole communicating the proximal and distal openings is prepared. A terminal of a rope is inserted through the proximal opening into the through hole, a portion of the terminal of the rope extended from the distal opening is loosened, and a diameter-enlarging member is fixed to a core wire of the rope. Then, the terminal of the rope is brought back into the through hole. A fixed width portion extending in an axial direction of the terminal metal fitting is pressed from the outside in a circumferential direction by swaging, such that a protrusion constraining the rope so as to reduce its diameter is formed in the through hole. The diameter-enlarging member cooperates with an end of the protrusion located on the distal opening side to constrain surrounding wires other than the core wire in a sandwiching manner. A rope with terminal fixing tools, which comprises the terminal fixing tools attached thereto by this method, is also provided.

Rope with radial seam and method for manufacturing
A rope comprises a core extending along a longitudinal axis and a sheath surrounding the core, the sheath extending along the longitudinal axis. A strap at least partially surrounds the sheath, the strap being separated from the core by the sheath. At least one thread passes several times through the strap, sheath and core to form several links fixedly securing the strap on the core and sheath. The links pass through a central section of the core, the central section corresponding to a circular section representing less than 50% of the cross-section of the core. The links are angularly offset from one another when observed along the longitudinal axis.

CABLE-DRIVING ARRANGEMENT OF A VEHICLE
A cable-driving arrangement of a vehicle includes a cable main body. The cable main body is composed of a plurality of unit filaments, and distal ends of the unit filaments are melted to be integral to form a melted end. The cable main body is for being relatively positionably disposed on a vehicle with a portion near the melted end.

Cable termination inspection cover assembly
A cover assembly for a synthetic cable having a termination end secured on a jacketed end of the synthetic cable is provided. The cover assembly includes a shell and an inspection port. The shell is configured to extend around and at least partially enclose a socket portion of the termination end of the synthetic cable. The inspection port is defined into the shell for viewing access of at least part of the termination end of the synthetic cable. The inspection port is positioned along a length of the shell that aligns with the socket portion of the termination end so that the socket portion of the termination end and the jacketed end of the synthetic cable are visible through the inspection port. The jacketed end of the synthetic cable extends into the socket portion of the termination end.
