This invention relates to a method and apparatus for sweeping dust and debris from the needles of a wand which is for applying an electrostatic charge to a plexifilamentary film-fibril web. The needles of the wand tend to acquire dust and debris from the polymer and by the present invention the dust and debris arcefficiently swept away by a gaseous fluid flow over the needles preferably so that the fuid passes circumferentially over the needles through an annular passage.
Technique et appareil d'expulsion de la poussière et des débris accumulés sur les aiguilles d'une baguette destinée à appliquer une charge électrostatique sur un tissu composé d'une pellicule fibrillée de filaments plexiformes. Les aiguilles de la baguette ont tendance à recueillir la poussière et les débris provenant du polymère. Grâce à la présente invention, la poussière et les débris sont efficacement évacués par passage d'un corps gazeux sur les aiguilles, de préférence de sorte que le gaz fasse le tour des aiguilles en empruntant un passage annulaire.
