A covering device for covering elongate objects such as low voltage, medium voltage and high voltage cables with insulating, conducting or sealing sleeves. The covering device comprises a folded elastic tubular member having an inner portion and at least one coaxially disposed outer portion overlaying the inner portion. The inner and outer portions are continuously joined at a circumferential edge. A first support core holds the inner portion in a radially stretched condition, and a second support core holds the outer portion in a radially stretched condition. As the first and second support cores are removed, the stretched article returns to an unstretched condition.
La présente invention concerne un dispositif couvrant destiné à couvrir des objets de forme allongée tels que des câbles BT, MT et HT au moyen de manchons isolants, électroconducteurs ou étanches. Le dispositif couvrant se compose d'un élément élastique plié comportant une partie intérieure et au moins une partie extérieure coaxiale venant recouvrir la partie intérieure. Les parties intérieure et extérieure sont réunies de façon continue au niveau d'un bord en circonférence. Un premier élément central support maintient la partie intérieure en état d'extension radiale, un second élément central support maintenant la partie extérieure en état d'extension radiale. Dès qu'on retire le premier et le second élément central support, les articles en extension reprennent leur état non étendu.
