beam, the pneumatic reversal unit on the traversing unit receives a switch-over signal. FA is either directly mounted on the Uhing rolling ring drive or on an intermediate slide. The forked light barrier is mounted at a correction angle that changes when the traversing unit reverses. system-inherent switching delays. A simple relay controller is responsible for signal processing with constant spool speed, a PLC is used with constant material speed and decreasing spool speed. The light barrier has proven to be the ideal solution in heavily soiled environments and where varying illumination and reflection conditions prevail. For application in confined spaces, in particular for stranding machines, Uhing is currently developing a system where a rolling ring drive’s end stops perform an automatic non-contact search for the correct reversal position. This system also allows for correction movements during winding, for example to adapt the pitch to bulging spool flanges or changed spool positions. Tensioning and clamping systems of the Easylock type also allows brake and torque forces to be transferred to the spool, and U-Clip, an element for easily securing spools on the shaft, are also shown. In the rolling ring drives sector Uhing shows the enhanced free movement lever for the RG 3-30-2 MCRF as well as the new RGK 20, the worldwide first rolling ring drive made of plastic. This compensates for The upward continuous Casting method – better known as the Upcast® system – was originally innovated and developed by Outokumpu in the late 60s for the production of oxygen-free (OF) copper and copper alloys wire rod. Since the startup of the first production unit in 1971 more than 160 other Upcast® units have been delivered worldwide, establishing it as the leading method in its line of production. Today the Upcast® legacy is carried on under the banner of Upcast OY, exhibiting its full range of single and double-furnace casting lines. Several interesting new developments have been introduced to the Upcast® system. Among these are: maximum output from a single-furnace system increased from 7,500tpa to 12,000tpa capacity; • Joachim Uhing KG – Germany Fax : +49 4347 90640 Upcast OY Booth F13

maximum output from a double-furnace system increased from 30,000tpa to 40,000tpa capacity; a new Omega-type inductor doubling the previously available power range, combined with a marked decrease in specific power consumption; a transistor converter type stepless power control system, offering reduced specific power consumption, increased inductor lifetime and the elimination of harmonic resonance effects.

Unitek Booth G06 Unitek is an international leader in providing innovative solutions for fixed centre crossheads and automatic colour change technology for the wire and cable industry. The company emphasises quality, productivity and a commitment to provide the ultimate support to the extrusion industry around the world. The Unitek team has a strong background in the extrusion and cable industry and is dedicated to providing intelligent, efficient solutions to the problems encountered by manufacturers. Unitek was established in 1979, initially to serve both the plastic processing and the cable making industry. Since the first product line of fixed centre crossheads, introduced in the early 80s, Unitek has earned a name for high quality products. Close contacts with cable makers and machinery manufacturers all over the world, high standards of research and development in innovative products and their application, and modern production facilities for precision and quality, has been the basis of the company’s philosophy from the start. During the ensuing years, Unitek was highly innovative in developing new solutions and implemented state-of-the-art technology.

The machines are as follows: a CNC tube and rod bending machine BMZ 61, which can take wire up to 13.0mm diameter and tube to 25.0mm; a CNC coiling and bending centre FMU 2.7 with a wire diameter in the range of 0.8-2.5mm; an electronic spring coiling machine FSE 23 with a wire diameter from 0.35-1.6mm. • • • Wafios CNC coiling and bending centre FMU 2.7 ▲
