Drum-twister type stranding machines general information.
Drum-twister type stranding machine is designed for stranding insulated and bare multi-wire cores. With the help of a Drum-twister, a high / medium / low voltage power cable is manufactured, these cables have round and sectoral structures of large wire section and lengths.
The special feature of the Drum-twister stranding line is that pay-off devices rotate pay-off drums around the line axis, making unscrewing/twisting of pay-off cores.
The movement direction of the line from left to right:
There are three operation modes for recoil devices:
- paying off without rotation
- paying off with S or Z rotation
- paying off with rotation, monitoring from the sector position detector
The sector position detector is a degree control system for each sector-shaped conductor. Each detector is located on an individual prop after the pay-off device.
The core is stretched through the inlet of the machine and clamped by rolls. The detector reads off the core degree and transmits a signal to the pay-off machine, which changes its position (horizontal degree) by lining up the pay-off drum (core) to the correct angle of the tool - die inlet.
The core stranding occurs in the tool - die. After stranding, it is possible to apply (wrap) tape, apply armoring tape, wire armor.
The rotation of the caterpillar draft device is synchronous with the rotation of the take-up device. The configuration provides for both separate draft drives and the take-up device, as well as lockstep synchronization by using the shaft with the common motor.
Our company provides the line complication with 2 variants of rotating take-up device:
- Rotating take-up cupola
- The standard version of the take-up cupola on the support rolls.
Rotating fork-type take-up device.
The take-up device is made on the basis of the pay-off device, witch has the rotation in the support bearing.
Advantages of the fork-type take-up device:
- Low noise level;
- Long life of the support mechanism;
- Convenient maintenance and operation;
- The receiving drum is installed from the line side, because it’s convenient observing point for the line operator, which takes care about the spreader device;
- Loading into a standard 40NS container is a fourfold saving on delivery without using a Flat Rack container.
Q&A for the drum-twister type stranding machine
The drum-twister type stranding machine is designed for stranding insulated and bare multi-wire cores. The main difference is that pay-off devices rotate pay-off drums around the line axis, making unscrewing/twisting of pay-off cores.
The sector position detector is a degree control system for each sector-shaped conductor. It is located on the individual rack after the pay-off device and reads off the core degree, ensuring the correct position of the core,while it pass through the tool-die.
The core is stranding in the tool-die after passing through the pay-off device. After stranding, it is possible to apply tape, armoring tape, wire armor.
The synchronization of the rotation of the caterpillar haul-off machine with the take-up device can be realized through separate drag drives and the take-up device, or through rigid synchronization by using the shaft with the common motor.
Our company provides two types of take-up device: the rotating take-up cupola and the rotating fork-type take-up device.
The rotating fork-type take-up device has a low noise level, long life of the support mechanism, convenient maintenance and operation. An advantage is also a convenient observing point for the line operator and the possibility of the shipping saving by using standard containers.
