pay-offs, take-ups and winding systems

Multi-end bobbin winding machine OMA Srl, Italy, has developed the BS 1 winder and CDE 250 motorised pay-off. On the BS 1 winding machine’s bobbin drive and traverse unit, the bobbin is driven by a torque controlled servomotor which maintains the required wire pulling tension, from empty bobbin to full. The traverse width and winding lay length are controlled by a servomotor electronically synchronised with the capstan speed. The motorised capstan pulls the wires from the pay-off stations, supplying them to the bobbin at a controlled tension. This allows the wires to be laid on a flat, smooth surface, so they are wound with the same length and tension. The electronic motor’s synchronisation allows easy parameter changes, and the constant wire linear speed (up to 700 m/min) maximises the winding efficiency. The safety protection cabinet’s transparent panels give good visibility and access, while ensuring the full protection of the operator.

The CDE 250 motorised pay-off unit features a modular system with up to 48 positions. Each spool is driven by an inverter controlled motor, allowing the easy set-up of different tensions. Individual wire tensions are controlled by drop weights on a vertical accumulator, which allows for different pay-off bobbins weights and wire supply bobbins quantity issues. The company’s automatic bobbin measuring device – model MB 1 – is a free standing steel cabinet which houses an automatic gauge, able to measure and store the exact traverse width of the bobbin and send the information to the BS 1 winder’s control program. This avoids the manual correction of the bobbin traverse width during the winding process, and the measurement is calculated to within one hundredth of a millimetre.

Wide variety from Fine F ine International offers a wide variety of pay-off and take-up systems for wires, cables and fibre optics applications. Shaft style pay-off machines are available for reel sizes from 250-800mm (10"-32") flange diameters, while units are available in drag or driven mode.

Multiple station units for fibre optic loose tube lines include catenary arm dancers for precise tensioning of each fibre. Shaftless payoff systems 500-1,800mm (20"-72") are manufactured to customer specification, based on line speed and overall reel weight considerations. Take-up units include belt driven or independently driven traverse units, and traversing reel variations are also available in many styles. Portal style units are available for reel sizes from 1,250mm-3,000mm (48"–120"). Take-up versions include independent traverse assembly, traversing reel or floor traverse. Automatic crossover take-ups are available for reel sizes from 500mm to 1,000mm (24"- 40"). Semi-automatic units can be designed for reel sizes up to 1,800mm (72"). Fine also manufactures a line of Figure 8 reelless spoolers which can be utilised in standalone respool lines or as an extrusion online system. Fine International – USA Fax : +1 732 933 4005
