How are braids made?
The carriers of a braiding machine run across horizontal, wave-shaped sliding tracks. As some carriers move clockwise while others move counter-clockwise, the attached threads become interlaced. As the carriers run in a horizontal plane while the finished braid is continuously pulled upwards, the interlaced threads are aligned diagonally to each other.
The threads running from top left to bottom right form part of the left thread system, while those running from top right to bottom left are part of the right thread system.
What are ropes?
A rope can be best described as
"a length of flexible cord used for the transfer of tensile forces."
Ropes can be classified according to a number of criteria
Stranded or twisted ropes or braided ropes
A distinction is made between fiber and wire ropes
Examples of ropes are suspension ropes;
climbing ropes; guy ropes, etc.
In the past, ropes were mainly made from natural fibres such as hemp, sisal and similar products. To meet modern requirements with regard to strength, elasticity, weight, etc., most ropes are now made from synthetic fibres. The most commonly used synthetic fibre materials found in ropes are polyamide, polypropylene, polyester and Dyneema.
What is a braid?
A braid is a textile product where the strands of yarn are not crossed vertically and horizontally like in a woven fabric, but interlaced at an angle to each other and also at an angle of the product they encase. A braid thus consists of multiple threads, some running from the top left corner to the bottom right corner, while others run from the top right corner to the bottom left corner.
Industrial braids are found in many devices and products and are often hidden from view. Braided products include shoelaces; cords in parkas; wicks in candles; rubber bands; decorative belts; ropes; washing lines; sewing threads, especially for medical purposes; medical catheters; industrial seals; composite components in machinery, and much more.
As industrial braids come in many shapes and sizes, it is not possible to list them all here.
What are carbon fibres?
Carbon fibres are synthetic fibres made from raw materials that contain carbon and have undergone a pyrolytic process so that the carbon atoms are bonded in the form of crystals similar to graphite. There are two groups of carbon fibres:
Isotropic fibres are of low strength and therefore rarely used in technical applications
and anisotropic fibres:
Anisotropic fibres are high-strength fibres with minimum elongation at break.
Carbon fibres are excellent electric and thermal conductors.

What are cords?
The term cords covers all products that are produced by braiding with two interlaced strands of threads.
The cross-section of a cord may be square, round, oval or trapezoid.
Many such products contain a core at the centre of the braiding.
Hollow cords are produced on round braiding machines and without a core at the centre of the braiding. The best-known hollow cord is probably the shoelace.
