Embodiment Construction

[0037]During the twisting process, the steel rope will break. However, it is desirable to obtain large lengths of continuous steel cords in order to obtain uniform and continuous reinforcing elements. The large length with the same diameter avoids difficulties during the rubberizing of the steel cord. Especially for a coupling where two steel cables are coupled together, it is desirable to obtain a strong connection and the same diameter or a minimum change in diameter.

[0038] Figure 1a The known assembly 10 shown consists of two steel cables 14 connected by a known connector type tubular fabric 100 . The diameter (radial thickness) of the assembly over the length of the tubular fabric is equal to the sum of the diameter of the steel cord itself and the radial thickness of the tubular fabric. The increase in diameter will therefore be large.

[0039] Connector tubular fabric or Chinese finger cots can have different embodiments, two specific embodiments are: one is shown...

Abstract

An assembly adapted for connecting two ends of a steel cord (14) comprises a connector tubular fabric (100) for connecting steel cords at two connecting ends. The steel cord is a multi-layer steel cord having a core and at least one layer and possibly a wrapping filament. At least one layer is absent at the two connecting ends of the steel cords over a total length L2 and the tubular fabric is positioned so that it fits within said total length L2 thereby avoiding an increase in diameter over the length L2.

Description

technical field [0001] The invention relates to a tubular fabric for connecting two steel cords, and an assembly consisting of two steel cords and a tubular fabric for joining said steel cords at the two connecting ends. The invention also relates to a method of connecting two steel ropes at the two connecting ends by means of a tubular fabric. Background technique [0002] Tubular fabrics, sometimes referred to as "Chinese finger cots", are known in the prior art for connecting two steel cables. The assembly 10 that Chinese style finger cot 100 and steel rope 14 constitutes is as Figure 1a , 1b and 1c shown. Figure 1a for portrait view, Figure 1b is the cross-section according to the I-I plane, Figure 1c is the cross-section according to the II-II plane. The Chinese finger cot 100 is composed of metal wires or wires 12 that are helically interwoven or braided to form a cylindrical braid. There are gaps 13 between axially and circumferentially adjacent and successive...
