Payoffs, take-ups and winding

Versatile take-up and payoff systems by Niehoff

The wire and cable machinery developed by Maschinenfabrik Niehoff covers nearly all wire and cable manufacture operations and includes a large range of take-up and payoff systems. Of particular note are the S-series single spoolers and the ARH tangential payoffs.

❍ The new design single spooler type S 631

The compact S 631 and S 801 spoolers with inte- grated dancers are suited as take-up systems for multi-wire drawing lines. A swivelling traversing roller assembly eliminates the need to turn the wire bundle before the take-up. The result is high quality spooling which assures that the wires can

be efficiently further processed at high speeds. The spoolers feature traverse and spool drives using AC servo motors and a hydraulic-pneumatic spool lifting table. The spoolers cover wires ranging from 0.15mm up to 1.60mm (34½ ... 14 AWG) and work at speeds up to 40 and 36m/s respectively (S631/7,900 fpm; S801/ 7,100 fpm). The ARH 630 and ARH 800 tangential payoffs with separate drive are designed for the non-twisting pay-off of individual wires, parallel wound wires as well as bundles and also well suited for the manufacture of high-quality and geometrical strands. A pneumatic dancer maintains constant wire tension, an MMI display is combined with back a tension indicator and an empty spool detection system. The ARH payoffs are available in single (left or right hand operations) or double payoff versions. They are designed to handle individual wires with a diameter of 0.4mm to 1.41mm (26 ... 15 AWG) and bundles with a cross-section of 0.157mm² to 6.00mm² (25½ ... 9 AWG) with corresponding maximum line speeds of up to 300m/min (1,000 fpm).
