Boosting cable production ▲ ▲ The patented ‘free pulley’ fromMacchine Speciali

pulley leaves the cable free to accept the twists imposed and allows cables to perform with variable back twist even in the presence of deviation of the product with deflection angles of 180°. This application allows the customer to take advantage of working in stranding with back twist and this gives a much better production performance. Under identical conditions, the multiplication factor is tested five times the traditional method. Macchine Speciali – Italy Website : www.macchinespeciali.it

Italian company Macchine Speciali has developed a series of plant and equipment tailored to the optimisation of cable production. Machines and equipment have been developed for rotating machines, double twist and single twist, and in the field of cold extrusion of materials such as PTFE and silicone. In the continuous technological evolution Macchine Speciali has designed, perfected, built and patented a device that is a pulley with multiple degrees of freedom simply called ‘Free Pulley’. This

New coiler from Bongard

Bongard has launched its new coiler – CU C 480.

This model has several design features that sets this coiler apart. It is made for copper wire from AWG 27 (0.35mm) to AWG 16 (1.2mm diameter), soft to hard, with a maximum coiling speed of 118 fps (36m/s). The new features include a modular design that makes the set up much easier as well an upgrade of more user-friendly features. Wear on the deflection pulley has also been reduced to a minimum. The fingers that press the wire onto the capstan are easy adjustable, and wear is reduced more than three times. Because of work on the accumulations system, there is no disturbance and a tangle free barrel change is guaranteed, while there is also a continuously adjustable rosette laying device.
