METHOD AND DEVICE FOR WELDING METALLIC FIBERS TO FORM A FLEECE BY REPEATEDLY CARRYING OUT A WELDING PROCESS, FLEECE COMPRISING WELDED METALLIC FIBERS

摘要

The metal fibres [3] are conveyor [16] fed through to a welding station [8,9] that have roller electrodes [11]. The electrodes are set so as to produce a multiplicity of welded connection points. As the fibres progress through the rollers the thickness of the formed fleece is reduced in thickness. The weld form provides stability for inclusion in an exhaust.
