What Is The Difference of The Double Group Braiding Machine And The Normal Braiding Machine
Key Part Difference:
Item | Normal single group braiding machine | Double group rope braiding machine |
Main structure | Single spindle braiding as a “8” route | Double group spindes, One group moves clockwise and the other group moves counterclockwise along a compound track |
Braiding Principle | All spindles are interwoven to form a braided layer. | The two sets of spindles are not only interwoven within themselves, but also interwoven with each other to form a compact solid structure. |
Rope structure | Usually hollow tube or flat ribbon. The structure is relatively loose. | Solid, high-density cylindrical rope with almost no central void |
Product strength and wear resistance | Low. Due to its hollow structure, it is easily flattened when subjected to force and has average wear resistance. | The solid structure makes the force evenly distributed and is extremely wear-resistant and pressure-resistant. |
Typical products | Shoelaces, clothing cords, decorative cords, wire sleeves, elastic bands, etc. | Climbing rope, safety rope, marine cable, traction rope, lifting belt core rope, etc. |
Production efficiency | Relatively high. | Relatively low, because the mechanism is more complex and the movement is more precise |

Detailed technical analysis
1. Standard Single-Group Braiding Machine
Working Principle: All yarn-loaded spindles are divided into two halves, one rotating clockwise and the other counterclockwise, in a common "figure-8" orbit. At intersections, the spindles bypass each other, interweaving the yarns to form a web-like or tubular braid.
Product Features:
Hollow Center: Because all yarns are interwoven on the same plane, a hollow hole naturally forms in the center.
Stretchable: When pulled, the tubular structure lengthens and tapers; when released, it rebounds.
Deformable: Easily flattens under radial pressure.

2. Double-Group Cable Braiding Machine
Working Principle: This is the key. The machine has two independent sets of yarn carriers (usually distinguished by different colors, such as Group A and Group B).
Group A spindles: Move along one track (for example, clockwise) on one level of the machine.
Group B spindles: Move along another track (for example, counterclockwise) on another level.
These two sets of tracks are interwoven. During the braiding process, the yarns in Group A not only interweave with the other yarns in Group A but also pass through the spaces created by the yarns in Group B and interweave with them, and vice versa.
Product Features:
Solid and Dense: The two sets of yarns "lock" together, filling the central void and forming an extremely strong, solid cylinder.
Extremely Strong: This structure ensures that the load is evenly distributed among all the yarns, resulting in extremely high tensile strength and abrasion resistance.
Stable: The structure is not prone to deformation or kinking.

How can you visually distinguish the two types of products?
Look at the cross-section:
Try pinching the end of the rope.
If it flattens easily and has a noticeable hollow space in the center, it's likely produced on a single-braid machine.
If it feels very firm and difficult to bend, and has a solid cross-section, it's likely produced on a double-braid machine.
Look at the application:
Ropes used for life support (such as mountaineering, rescue, and ship mooring), high-strength traction, and heavy lifting are almost always double-braided.
Ropes used for everyday bundling, decoration, clothing, and other low-strength applications are mostly single-braided.
