Conotorsion technology from Cortinovis Machinery m m

Single-twist for shallow bending

On this cable, wires from static payoffs can be applied for making copper or aluminium screens or steel wire armouring. Conotorsion lines frequently make both screening-armouring and lying up of insulated cores for control instrumentation cables. The simple process allows a wide range of payoffs for wires from coils, packs or bobbins, according to the process requirement. The stationary line of wires allows the easy application of wire straighteners. On the line, a wide range of taping heads can be inserted.

Conotorsion accommodate bobbins fitted between pintles from 1,000mm, 1,250mm 1,600mm and 2,200mm. The direct pull has digital speed control. Conotorsion can be used with all types of payoffs, with or without back twist, and bobbins driven with AC motors or with mechanical or pneumatic brakes. Conotorsion machines are available for wire armouring and screening, for payoff bobbins and take-up bobbins of 1,000mm to 2,200mm. The wires payoff range includes stem packs with copper, aluminium or steel wires. For armouring and screening, one Conotorsion payoff rotates synchro- nised with a Conotorsion take-up, and rewinds the cable put in rotation. In the take-up, as an option, an integral double capstan can be installed to allow higher tension in take-up. will

Cortinovis Machinery produces the Conotorsion machine, based on the single twist method of work. Conotorsion can provide improved quality on larger and rigid cable con- structions, due to shallower bending angles. In-line taping and binding heads and wire payoffs can be used for applying armouring, screening, taping and binding. The Cortinovis Machinery Conotorsion features the high speed of the single twist process, up to double that of comparable drum twisters. It can produce rigid and large diameter cables, due to the very soft deviation that is characteristic of this rotor design and the optional double capstan. Conotorsion high-speed machines can be used for laying-up of control and instrumentation cables, pairs, three cores, and quads.
