During the manufacture of rotors and stators from electrical steel strip, clean surfaces are particularly important. Metallic particles on the surface can penetrate the thin insulation layer on the electrical sheet, causing a short circuit. To prevent this, the electrical steel strip must be cleaned very thoroughly before processing. Contaminating particles can also damage the rollers of the leveller and accumulate in transport units. Deployed for strip cleaning from both sides prior to levelling, Sword Brush® technology has a proven track record. The Sword Brush® delivers high-performance cleaning results in continuous operations and ensures a stable and errorfree production process. The Combi Sword Brush Una XE-B 112 only requires a single-sided adjustment frame with one column and, thanks to a space-saving footprint, can easily be integrated into the production line. Narrow electrical steel strip is cleaned effectively from above and below.
