which are positioned around the rod circumference and aggressively clean the rod surface of secondary scale and red rust, which are detrimental to producing high quality wire products. Unique to the Wilco wire-brushing machine is the pressure of all wire brushes being automatically maintained on a real-time basis by the advanced electronic control system.

ve or seven individually adjustable rolls. Each straightener is equipped with straightening rolls in two rows. However, two versions are o ered, using a di erent number of straightening rolls dedicated to the side of the straightener with the roll adjustment screws. By using di erent straightener versions a perfect adaptation is possible, considering the wire transport direction, the location and the orientation plus the turning direction of the spool respectively of the coil. Bad straightening results by lost bending operations are history, whatever the turning direction of the coil respectively of the spool. The RT series straighteners do not have a mechanism for quick opening/closing, which is installed on the RTS series straighteners.

There are still cable manufacturers preparing material mixtures by hand, and the risk of wrong mixtures or separation of material is very high. Reproducibility cannot be guaranteed. The rst real automation for the dosing of materials in the cable manufacturing industry was the implementation of the “Wilson Color-O-Meters” (disc dosing units), which were mounted on the main material hoppers, reducing the human factor. The disadvantages of such systems were the high maintenance, the comparatively di cult handling, the risk of material separation when having di erent material densities (stirring devices had to be used), as well as material spreading around the equipment. With the introduction of screw feeding dosing units, the above systems were replaced step by step. Screw feeding dosing equipment was installed between the main material hopper and the material inlet of the extruder. The separation of material was eliminated. Changeover periods were reduced drastically. Handling was improved and the spreading of material around the equipment was stopped.

The 1250 automatic brush descaling system

The operator is not responsible for making manual adjustments to the brush pressure; therefore the brusher will produce a consistently cleaned wire rod. Additionally, when the wire brushes need replacement (typically after processing 300 tons of wire rod) the control system will shut down the Wilco brusher while illuminating an indicator lamp communicating the machine’s condition and that the brushes need replacement. Additional models of Wilco descaling systems are available from basic, non-aggressive systems to its full-featured automatic brush descaling system with lubricant pre-coating. Witels-Albert will be presenting both new and eld-proven solutions from its range of straightener, roll, guide, feed and pre-former products. Using ‘performance at its best’ as its motto, the company will turn the spotlight onto the new straighteners from the RT and RTS series. Visitors can see the new straightener products in action and nd out how good they are. Key factors determine the performance of the new RT and RTS series straighteners. New materials and new standard parts, the multiple usage of single parts and a highly developed assembly and production represent the performance of the new straighteners, which are available with Wire Lab Company – USA Website : www.wirelab.com Witels-Albert Stand: 09E39

New range of straighteners

Straighteners in the RTS series can be opened and closed quickly and easily with only a small amount of force. The complete new mechanism for opening and closing an RTS series straightener is very robust and reliable as it is protected against dust and dirt deposits formed from, for example, drawing soap and coating chips. Driven by the intelligent design, RT series straighteners can be converted into straighteners of the RTS series by the user at any time. All the RT and RTS models cover a wire size range between 0.1 and 9mm. In total eight unit sizes are o ered. All models are prepared for managing double-plane straighteners using two straighteners and a connecting bracket in between the units. The connecting brackets can be retro tted, which also supports the design of customised straightening systems consisting of three or four single plane straighteners at any time. As the connecting bracket design allows the continuous adjustment of the angle in between the units, straightening chains can be manufactured and used for straightening wire in di erent planes.

Some of these systems are still being used. In comparatively basic production methods when the speed of the extruder is not or very rarely changed (ramping) and when the requirements to the quality of the mixture are minimal, this way of having a dosing unit synchronised to the speed of the extruder is still common. The speed (RPM) of the dosing unit is synchronised with the speed of the extruder (capacities are not synchronised). However, the requirements to the product properties have increased over the past 30 years and new products need highly precise dosing solutions. As an example cross-linked and foamed (chemical foaming) products are to be mentioned.
