WTM cable rewinding line with test and back-to-fault functions

Cable manufacturers demand top quality not only during taping and stranding, but also in the final rewinding stage. This critical phase involves winding the finished cable onto the reel that will be delivered to the customer. To ensure the absence of defects and to meet the highest quality standards, each cable undergoes rigorous testing using advanced quality control equipment before final rewinding.

A rewinding line that integrates all necessary control and, optionally, marking devices into a single, streamlined process is the most effective solution.

WTM has further enhanced its cable rewinding lines to offer maximum operational flexibility and adaptability to a wide variety of cables, both round and flat. Each line includes:

• motorized pay-off, available in stationary or traversing versions;
• cable tension control via dancer arm or direct torque, depending on cable characteristics;
• tension monitoring through load cells;
• configurable quality control and marking units, tailored to customer needs;
• traversing take-up unit;
• protective film applicator.

The instruments to perform quality controls on the cable includes:

• spark tester
• laser diameter gauges
• lump & neck detector
• length counter
• industrial printer
• "Back-to-fault" function: if a defect is detected, the machine stops and rewinds to the exact fault location for immediate intervention.
