Set up is by control panel, and an electro-mechanical or pneumatic self- compensated brake controls tension of the cores. Safe use is maintained by control of bearing temperatures and vibration and the machine is protected with a pneumatically controlled soundproof cover, inside fans and lights. High productivity bow type laying-up machines can be used for round and straight sectoral insulated cores for low voltage cable. Cortinovis bow stranders
