State-of-the-art measuring from Sikora For continuous online quality control of wires and cables, Sikora delivers state-of-the-art devices for diameter, wall thickness, eccentricity and ovality measurement, detection of lumps and neck-downs as well as spark testing directly on the extrusion line. Important for extrusion operations, the Sikora technology features outstanding quality and reliability, through the use of state-of-the-art X-ray and laser technology with no requirements for calibration. The use of very fast digital signal processors eliminates effects of vibration or environmental influences, which ensures unprecedented accuracy and long-term stable measurement data. Sikora presents the measurement data through operator friendly display and control interfaces. The display options provide simple through to comprehensive statistical analysis, data collection and print capabilities. The proven automatic control of the extruder output or the line speed provides fantastic return on investments through material consumption savings. Leading Sikora’s future-oriented product developments today is the innovative X-Ray 2000 series for diameter and wall thickness measurements on insulation

and jacketing lines and the Centerview 2000 series for non-contact eccentricity and diameter measurements on LAN, coaxial, RF, telephone cables, automotive and building wires. The success of the X-Ray 2000 comes from Sikora X-ray experience applied to satisfying the customer demand for a reliable solution for on-line measurements of the wall thickness, diameter, eccentricity

and ovality without any undue time delay during production process. Start-up scrap is minimised, the material consumption optimised and the line productivity is increased dramatically.

New pay-off fromMobac The worldwide supplier of products and machines for the wire and cable industry, Mobac, has developed a new driven tangential pay-off with tension and rpm control. The DP630/800AT is a universally applicable and easily loading operational pay-off for single and multi-wires. The pay-off is controlled via a dancer arm by means of a sensor and frequency inverter and is used to feed extrusion lines and bunching machines as well as stranding machines. The spool shaft with bearings on one side is driven by an AC synchronous motor with frequency inverter. It is also available as a doublehead machine. The pay-off is appropriate for coils with flange diameters of 630-800mm and achieves a maximum wire speed of 450m/min with wire tension of 1,2N to a maximum 100N. The tension range is adjusted by current control and frequency adjustment of a standstill motor that gives back tension to the dancer arm. Mobac GmbH Kiel – Germany Fax : +49 431 650511
