WTM single-twist stranding line: single shaft design for special cables

Cables employed in high-tech sectors such as automotive, robotics, telecommunication, instruments, data transmission, energy, and more need to be characterized by extreme flexibility and accuracy in their lay length: with this focus, WTM designs and builds its single-twist cable stranding machines.

According to the working preferences and the cable specifications provided by the customer, the company selects the layout configuration and designs and produces a machine tailored to the production requirements. The cable quality, achieved thanks to accurate tension control on both wire and tape and the precise stranding pitch, will guarantee customer excellence in its business.

In particular, the single-shaft model is characterized by a smooth deposition path, obtained by angles and pulleys properly designed to bend the cable during the winding phase as little as possible, and the “low-stress” wire guide principle, that erases the reversing stress on the cable: these two key points make this solution ideal for a wide range of cables, even complex and sensitive.

• back twist pay-offs, with twist control from 0 to 130%, for reels from DIN 400 to DIN 800, in single or multiple overlaying configurations (according to the reel dimensions), and valorized by a dancer tension control; the back twist setting and the constant tension control allow producing highly flexible stranded cables;
• rotating capstan, with the possibility to act as master of the line that pulls the cable and controls the tension with the integrated dancer, or as slave in case the tension required increases;
• longitudinal tapers, single or double, to wrap the stranded cables with tapes taken from spools, pads and even jumbo spools, with tension control by dancer;
• concentric tapers, to finally close the cable with tapes taken from pads or spools, with tension control by dynamic dancer or torque control, in order to have a very wide application range.

The guiding principle of all units that make up the cable stranding lines is attention to detail, which sets WTM equipment apart from any other competitor. The company thanks all its customers who have enabled it to achieve this goal, raising the technological level, improving the cabling process, and making the operators’ life easier.
