Double head backing twisting refers to a process in which two wires or cables are twisted together while simultaneously applying a back twist. This technique is commonly used in the wire and cable industry to improve the overall performance and stability of twisted pairs.
Function and Usage:

Double head backing twisting machines are specifically designed to twist and back twist pairs of wires or cables, such as CAT cables (CAT 5, CAT 5e, CAT 6, CAT 6a).
The twisting process involves twisting two wires together to form a pair, while the back twisting process applies a reverse twist to the pair, reducing the overall twist length and improving the electrical performance of the cable.
Features and Specifications:

Inlet Wire Diameter: The machine can handle wires with a diameter ranging from 0.4mm to 1.5mm.
Speed Regulation: The machine offers step-less speed regulation through electrical settings, allowing for precise control of the twisting process.
Pitch Range: The pitch, or distance between twists, can be adjusted within a range of 4.96mm to 39.64mm by changing plastic gears or using digital setup options.
Twisting Direction: The machine can twist in either a left or right direction (S-Z).
Take-up Bobbin Size: The machine is equipped with take-up bobbins with a size of φ50056300mm.
Take-up Capacity: The maximum take-up capacity of the machine is less than 250kg.
Traverse Way: The machine utilizes a polished rod for traversing the wire during the twisting process.
Center Height: The machine has a center height of 775mm.
