The absence of the distributor equip- ment is said to markedly reduce ow resistance inside the furnace. Hence the required blower capacity can be lower than that of competing designs by about 20 per cent. Additionally, the new design no longer requires a stand-by blower in the event of a power failure to provide cooling air to cool the steel structures. As the combustion gas is premixed outside the furnace, the new design achieves a uniform fuel/air mixing ratio throughout the uidised bed and an homogeneous temperature distri- bution over the width and length. This results in higher combustion e ciency and lower emissions of unburned hydrocarbons. Wire Körner GmbH – Germany Fax : +49 2331 800 688 Email : info@wirekoerner.com Website : www.wirekoerner.com WTM Srl Stand: 11E77 WTM will display its new high-speed horizontal taping line for at wires. The line will be equipped with a new caterpillar combined with a capstan pulling drum with two taping heads in the wrapping section. The con guration allows synchronisation and control of the tape and a speci cally designed vision system allows overlapping of the two heads. The rst head lays the tape edge- to-edge, completely covering the cable, while the second head, synchronised with the rst, lays the tape in the middle to provide a full covering of the conductor. To control and adjust the position of the second tape, a high frequency camera captures images, and detects in real time the displacement of the second tape compared with the rst. This generates a feedback signal that adjusts the speed of the second head and, consequently, the position of the second tape compared to the rst, obtaining a perfect and constant mutual displacement. This line will be presented with two di erent taping heads. The rst head is suitable for large dimensioned cross-wound spools up to 300mm

diameter or 130mm height and up to 12kg in weight. It maintains a constant production speed of 2,500rpm. Two motors, synchronised by a high sensitivity electronic dancer, provide direct tape tension control for the most sensitive materials. The second head, suitable for medium sized cross-wound spools, will be provided with a new electronically driven friction that continuously adjusts

the tension of the tape by means of an electro-mechanical dancer. Both heads give the operator the possibility of adjusting the tension of the tape while the machine is working. New models of payo and take-up units complete the line. WTM will also display its new high performance single-twisting machine, for small and medium exible cables, with the option of using DIN bobbins of 630mm diameter up to 1,000mm.
