New laser devices will expand Sikora’s current range of diameter gauges by three powerful models, said to offer even higher precision and reliability, thus effectively improving the efficiency of the production line. The 2,500 measurements per second provide extremely high single-value precision, ensure an optimum line control and provide reliable statistical data. With the new measuring devices the cable diameter is measured with an accuracy of up to 0.2 micrometres. Sikora engineers have integrated a number of practical improvements. The opening of the gauges is twice as large as the measuring range, to ensure an easy cable feed through. Directly integrated into the gauge head is a new, pluggable universal interface module for all connections. In this position it is protected against water, dirt or mechanical influences during production. Another highlight is a specially developed over-voltage and over-current protection, which is serially integrated into the devices. A special feature, carried over from the larger Laser Series 2000 gauges, is the swivel gauge head design. It allows for the gauge head to be easily moved up, out of the extrusion line. The measuring axes are arranged in such a way that the gauge is open at the bottom to prevent dirt and water from falling into the measuring area. Precision measurement 3

TCD lines to China

Radyne IHWT has completed the supply, installation and commissioning of induction heating equipment for six tyre cord diffusion (TCD) lines in China, each capable of running 24 wires at 80DV for wire diameters in the range of 1.1mm to 2.2mm. Each of the six lines included a pre-heat zone and a final heat zone, each supported by an IGBT power source, followed by two muffle temperature holding zones. The tyre cord diffusion process is done to prevent corrosion of wire within the tyre itself and to act as a lubricant for further wire diameter reductions in subsequent drawing operations. There are said to be many advantages and benefits associated with Radyne TCD systems, such as high electrical efficiency and contact-less heating without the need to heat media (such as sand). The system is operator-friendly and includes a control system with a Siemens HMI that is an integral part of the operator control desk and communicates with the Siemens Simatic series PLC using the Profibus DP protocol. This allows operator access to all machine parameters and controls, in addition to providing diagnostic information. Most importantly the Radyne TCD system ensures product consistency with perfect diffusion of both copper and zinc. Multi-wire heating at high DV can be achieved and it is also simple to change over from one wire diameter to another.
