摘要

Cleaning both edges of a sheet prior to welding. According to the invention, a laser beam (22a) is directed towards the two edges (12a, 12b) brought close together and displaced in a straight line, and focusing means (23) are provided in order to displace and/or shape the focused spot so as to cover, at least traversely relative to the path of the edges, a dimension equal to the width to be cleaned.
