Problems solved by technology

However, where it is desired to obtain a continuous rope from such an assembly, the tensile strength at the joint portion is rather poor, since the thickness of the resin may not be easily controlled, which may cause a weaker tension between the two ends of the steel rope. join
Even in the case of using resin between the ends of the tubular fabric and the outer wires of the steel cord, the tensile strength at the connecting portion is not satisfactory

Embodiment Construction

[0035] The wire rope may break during the twisting process. However, it is desirable to obtain a longer length of continuous rope in order to obtain a uniform continuous reinforcing element. Having a longer length and not losing too much breaking load on the fracture surface will avoid difficulties in the rubberization of the rope. Especially for the joint part (the joint part is the part where the two steel ropes are connected together), it is desirable to have a strong connection and the same diameter or minimum change in diameter.

[0036] Figure 1a The known assembly shown in is composed of two steel cords 14 connected by a known connector-type tubular fabric 10. The diameter (radial thickness) of the component over the length of the tubular fabric is equal to the sum of the diameter of the steel rope itself and the radial thickness of the tubular fabric. Therefore, the diameter has a large increase, such as by Figure 1b versus Figure 1c The comparison is visible. In add...

Abstract

An assembly adapted for connecting two ends of a steel cord (16) comprises a connector tubular fabric (10) for connecting steel cords at two non-overlapping connecting ends, the tubular fabric positioned so that it at least partially overlaps with the two steel cords, further the two ends of the tubular fabric are connected to the steel cords by means of a solder. Such a solder may comprise tin-lead alloys or a lead free solder type. By means of such a solder, the join between the tubular fabric and the two ends of the cords is considerably improved thereby increasing the tensile strength at level of fracture.

Description

Technical field [0001] The present invention relates to a tubular fabric for connecting two steel ropes and an assembly composed of two steel ropes and a tubular fabric, the tubular fabric being used for connecting the steel ropes at two non-overlapping connection ends, and , Both ends of the tubular fabric are connected with steel ropes by brazing. The invention also relates to a method for connecting two steel ropes with a tubular fabric at two non-overlapping connection ends by brazing. Background technique [0002] For example, the tubular fabric used to connect two steel cords is known in the art and is sometimes referred to as "Chinese finger." This prior art tubular fabric 10 for connecting two steel cords is shown in FIG. 1. It is composed of metal wires 12 that are spirally woven or braided to form a cylindrical braid. There is a gap 13 between adjacent continuous metal wires 12 in the axial direction and in the circumferential direction. The formed diamond-shaped me...
