Single and double twist bunching machines are the two different machine types.
1. Single Twist Bunching Machine:
The single twist bunching machine is a spinning of the take-up reel around its center axis.The Single Twist Bunching machine is limiting the bending radius of the incoming individual products. In case the small achievable bending radius of the single conductor is bigger than the bending radius inside the single twist machine. Another way of production has to be selected for example drum twister. Thanks to modern control technology. The single twist bunching machines can perform good stranding results for the entire production length.
2. Double Twist Bunching Machine:
The double twist bunching machine is making two twists in turn of the bow.
The elements doing to be bunched are outside the machine housing and are going to the lay plate in front of the machine. From the lay plate, they are going through the bow where the two twists are added before going onto the spool or bobbin.
Double Twist Bunching Machine is used for stranding multi-stranded copper wires, tinned wires, enameled wires, and copper-clad aluminum wires.
Double twist bunching machine which runs on a process usually with no back twist. Suitable for the stranding of 7 copper wires (class 2) as well as for bunching of many fine copper wires (class 5).
