Making a rope

Making a rope involves several steps:

1. The choice of raw materials

Matières premières

The choice of raw materials is essential: these will be checked and tested to verify the correspondence of the desired characteristics.

Internally, we talk about “wisp” but for more understanding the term “threads” is more appropriate. The origin of raw materials is different for different materials. It all depends on quality, price and other parameters.

2. Assembly

Assemblage des fibres

The next process is the creation of a stream of parallel threads called the assembly.
At this stage there is no twisting or braiding.

3. Twisting


Then comes the stage of twisting, which consists in giving a twist to the wisp (thread) to give it mechanical values. Twisting consists of twisting the thread in 2 directions: in “S” when twisted to the right; in “Z” on the left.

Then you get a twist.

4. Wiring


The wiring phase is not automatic. It depends on the ropes.
Wiring consists of applying a twist in the opposite direction to the 1st twist.

5. Dubbing

Once the twisting and wiring is completed, the dubbing takes place.
At dubbing, the coils of the raw materials which have been assembled, twisted and for some cabled, are filled.

6. Braiding


The operation of the braiding consists in braiding the product whether in core or sheath.

To these steps are added quality tests, finishing and packaging (winding, labelling).
