Description and Application
As the first-of-its-kind Skip Stranding Machine with integrated full back-twist functionality, this equipment sets a new standard for efficiency in the wire and cable processing industry. Unlike traditional cradle-type cabling machines, our skip strander delivers 4 times the productivity—specifically, a linear speed of over 40 meters per minute—making it an essential piece of equipment for high-volume production. It performs exceptionally well in skip stranding operations, capable of handling soft-structure cables (including control cables, Aluminum Conductor Steel Reinforced (ACSR) overhead cables, and power cables) as well as bare copper, aluminum, and aluminum alloy wires, with support for up to 7 cores.
The core mechanism of this equipment draws inspiration from the bow type laying up machine and is combined with back-twist functionality. This combination ensures uniform stranding, which stands as a key advantage over basic machines.
Features
1. Equipped with a user-friendly human-machine interface that allows for easy operation and comprehensive equipment monitoring, enabling new operators to master the use of this equipment quickly.
2. Utilizes PLC (Programmable Logic Controller) for automatic pitch adjustment, which maintains precision during skip stranding processes and reduces errors caused by manual operation.
3. Supports a back-twist mode of up to 100%—a distinctive feature that makes it more versatile than standard bow stranding machine models.
4. Provides two drive options: independent drive or ground shaft drive. This flexible design caters to various production requirements, allowing the equipment to be used either as a standalone skip machine or in combination with other devices.
5. Adopts AC induction servo motors, which ensure reliable and energy-efficient operation. This not only guarantees long-term stable performance of the equipment but also helps lower overall operational costs.

Main Components
1. Stranding host (integrates all payoff bobbins to achieve full back-twist functionality, serving as the core component that enables the Skip Stranding Machine to operate efficiently).
2. Filler payoff stand (an optional component that expands the range of applications for the equipment).
3. Assembling die holder, which ensures accurate positioning of strands during the processing phase.
4. Central taping machine, which works in conjunction with the skip machine to enhance the structural stability of cables.
5. Armouring machine, compatible with the skip strander and used for the production of armored cables.
6. Meter counter, which provides precise length measurements for the cables produced by the equipment.
7. Capstan/Haul-off/Caterpillar, which ensures smooth traction of cables during operation.
8. Take-up with traversing, which enables the orderly winding of finished cables.
9. Control system, which coordinates the operation of all components to ensure seamless performance of the equipment.
10. Transmission system, which guarantees stable power transfer to support the high-speed operation of the equipment.
11. Wearing parts (components crucial for extending the service life of the equipment, such as tension wheels and wire guides—spare parts are included in the initial delivery to minimize downtime).
Q&A
Q1: Why do I not see other brands producing this kind of machine?
Ans: Currently, we are the only Chinese company that integrates back-twist functionality into this specific Skip Stranding Machine form factor. This unique design allows our equipment to outperform both machines with a similar appearance and traditional cradle-type stranding machines. The equipment’s structure, based on the bow type laying up machine, combined with the efficiency of skip stranding, gives it a one-of-a-kind advantage that no other brand has yet replicated. This advantage ensures higher productivity and better stranding quality.
Q2: How to determine the right model of Skip Stranding Machine for my production needs?
Ans: The selection should be based on your wire parameters, as each model is optimized for specific skip stranding scenarios:
1. 1250 model (with back-twist): Each core has a cross-sectional area of 10mm² - 240mm², supporting up to 5 strands—ideal for medium-cross-section cable operations.
2. 1600 model (with back-twist): Each core has a cross-sectional area of 30mm² - 300mm², supporting up to 5 strands—suitable for cables with larger cross-sections compared to the 1250 model.
3. 1250 model (without back-twist): Each core has a cross-sectional area of 7mm² - 28mm², supporting up to 7 strands—a cost-effective option for basic stranding needs.
4. 1600 model (without back-twist): Each core has a cross-sectional area of 9mm² - 50mm², supporting up to 7 strands—designed for high-capacity multi-core cable processing.
If you are transitioning from a traditional machine, our team will provide a comparative analysis to ensure the selected model aligns with your production upgrade goals.
Q3: What is the maximum stranding speed of the Skip Stranding Machine?
Ans: For the two models with back-twist (1250 and 1600), the maximum rotation speed is approximately 100 rpm. When using non-woven wrapping, this translates to a linear speed of 40 - 60 meters per minute. This speed represents a significant improvement compared to traditional cradle-type machines (which only reach 10 - 20 meters per minute) and even high-performance bow stranding machine variants.
Q4: What after-sales support do you provide for the Skip Stranding Machine?
Ans: We offer comprehensive after-sales support, including:
• Warranty: A 12-month free warranty for the entire machine (excluding wearing parts—spare parts are included in the initial delivery to minimize downtime).
• Technical support: 24/7 online consultation (via email, phone, or video call) to help resolve common issues, such as uneven skip stranding and abnormal noise.
• Spare parts: We maintain stock of core parts (such as motors and control panels) to ensure quick delivery, keeping your production operations on track.
• On-site service: If the machine experiences major faults that cannot be resolved remotely (e.g., transmission system issues), our engineers will provide on-site maintenance. Service fees are waived during the warranty period; after the warranty, only travel expenses are charged. We also offer training for your team to handle routine equipment maintenance.
