A double twist bunching machine is a specialized piece of equipment used in the wire and cable industry for stranding or bunching multiple wires together to form a single strand. It is commonly used in the production of various types of cables, including power cords, automotive cables, Ethernet cables, and speaker wires.
Working Principle:
The double twist bunching machine takes in individual wires and assembles them into a bunch or a strand. The machine uses a double twist mechanism, where the wires are twisted together in a specific pattern to create a tightly bound strand. This process can be carried out with both flexible and rigid wires, and with either bare or insulated conductors.
Features and Benefits:
High Performance: Double twist bunching machines are designed for high-performance stranding, allowing for efficient and fast production of cable strands.
Versatility: These machines can handle various types of wires, including copper wires, tinned wires, enameled wires, and copper-clad aluminum wires.
Construction: The machines are built with a welded steel construction and a stress-free annealed heavy-duty frame, ensuring durability and stability during operation.
Direction and Safety: Double twist bunching machines can operate in both left and right directions, providing flexibility in the stranding process. They also feature solid high tensile steel and an aerodynamic design for low friction and a gentle wire path. Safety features are incorporated to ensure operator safety.
Constant Lay Length: The machines use slip-less gear-driven idler pulley capstans to achieve a constant lay length, even during acceleration and deceleration.
Typical Applications:
Double twist bunching machines are available in various models, each suitable for different applications. Here are some examples:
BM-300: Suitable for earphone cables, USB cables, and Ethernet cables.
BM-500: Ideal for USB cables, automotive cables, HDMI cables, power cords, and speaker wires.
