Abstract (en)
In order to control the air-gap of a coiled article with magnetic circuit (2, 3), lead beads (7, 8) and spots of adhesive (5, 6) are placed inside this air-gap. Regulated squashing of these beads allows easy and automatic control of the inductance of the coiled article. <IMAGE>
Abstract (fr)
Pour régler l'entrefer d'un produit bobine à circuit magnétique (2, 3), on dispose dans cet entrefer des billes en plomb (7, 8) et des points de colle (5, 6). L'écrasement contrôlé de ces billes permet de régler facilement et automatiquement l'inductance du produit bobiné.
