Straightening units and guides Straightening units and systems are essential components of wire production. Witels-Albert GmbH, a leading supplier of straighteners and guides, has recently developed new roller straighteners for wire dry drawing applications. Minimised deformation under load, high precision and a reliable quick response locking mechanism (suitable in particular for high-strength wires) are features of the new RS straightening units.

Butt welders

Microwelder is a range of elec- tric resistance wire butt-welding machines from Rymer Engineering. The EH series are suitable for various materials and, depending on model, will handle ferrous materials of 0.9 to 9.5mmdiameter or non-ferrous of 0.9 to 6mm diameter. The EH series is supplied mounted on a wheeled trolley. The SG series, depending on model, is suitable for ferrous materials between 0.3mm and 2mm diameter or non-ferrous wires of 0.5 to 3mm diameter. A wheeled trolley is available for the SG series if required. The energy efficient Microwelder units are adaptable for round, flat or shaped materials or sections. Portable, light and compact, they are easy to handle and simple to operate. Suitable grinders are available and Rymer will also supply spares and service.

RS series precision straighteners ▲ ▲

Roll adjustment mechanisms are located on one side of the straightener. The roll diameter and the distance between straightening rolls have been optimised in order to straighten process materials with a wide range of diameters. The straightening rolls can be re-greased and are prepared for resisting high speeds and high loads. As an option, alternative roll materials or specific coatings can be realised. Straighteners in the RS series are available in five sizes for straightening wires between 1.5mm and 9mm diameter. Witels-Albert believes that the RS series roll straighteners overcome the disadvantages of using the drawing die for wire straightening, such as non-uniform distribution of tension and variations in material structure across the diameter. Using the drawing die for straightening can result in a finished product quality that makes handling difficult in downstream processes.
