WTM to unveil new screening machine for ultra flexible cables
WTM has designed and manufactured a shielding line for ultra-flexible cables to be employed in the aeronautical sector and in all those applications that require extreme conductor flexibility.
The machine consists of a full back twist DIN 630 pay-off, a rotating capstan, and a single-twist stranding machine, also suitable for DIN 630 reels.
In details, the cable to be shielded, taken from the unwinding reel, is pulled by the capstan with programmed linear speed and rotated on itself, and then finally collected in the reel of the single-twist collecting unit.
Before entering the rotating capstan, 96 copper-coated wires are taken from an unwinding creel and applied, through a stranding star, on the conductor surface; the cable is then spiraled with almost total coverage of its surface.
In contrast to the braiding process, shielding a conductor through this spiraling process guarantees a high production speed and enables obtaining a final product with very high flexibility.
For more details, feel free to contact WTM staff to ask for any necessary clarification.
