News Technology Measurement and detection of lumps and neckdowns

In addition to Sikora’s classic diameter gauges of the Laser Series 2000, the company offers the high-end devices of the Laser Series 6000. These diameter-measuring devices are specifically designed for sophisticated customer requirements that exceed the classic demands for quality control in the wire and cable industry. Up to 5,000 measurements per second, all with extremely high single value precision, allow for an optimum line control and provide reliable statistical data. The gauge heads measure the diameter of wires and cables with precision and repeatability. Sikora offers three gauge head models for product diameters from 0.2 to 78mm. The Laser Series 6000 also precisely measures transparent products. The devices include an integrated LCD display with control panel. This provides the operator with diameter values at a glance, directly at the measuring device. At the control panel the diameter nominal value can be entered and the control module activated. Via line speed or extruder rpm the module controls the diameter automatically to the specified value. A new ‘bullhead’ tubular strander for armouring optical and special cables is presented as an alternative to the classical planetary or tubular stranders. Caballé has upgraded and improved the existing technology of bullhead stranders with some major improvements: Five times more productive Number of steel wires up to 36 Pay-off bobbins: DIN 500-630 Central tube reel size: DIN 1600-2500 • Tension control core by motor/dancer system • Dual compensation mechanical system that keeps wire tension fully constant • Optimal management/information of alarms in the main screen with alarm description and position (nº of payoff) • Maximum stranding speed: 500rpm With this system the central core with the fibre optics inside is paid off completely The high measuring rate of the diameter • • •

devices also allows the detection of lumps and neckdowns. With the two-in-one system, investment costs are reduced. In addition, there is more space in the line, as only one gauge head has to be installed.

In the production mode the productivity of this machine is up to five times higher than a planetary strander. The possibility to work with up to 36 wires in a single pass makes this machine very versatile, as well as a high productivity line, being able to armour optical and special cables with high tensile strength steel wires. The ‘bullhead feeder’ has been designed to allow a wide range of working tensions, which makes it suitable for a single steel tube with fibres inside as well as for an armoured cable with a first layer of steel wires.
