The present invention relates to a method for covering an elongate object (11, 12), in particular an electric cable or a pipe. The method comprises the steps of. a) providing a covering assembly (40) which comprises: 1) a tubular elastic covering element (26) having at least one end which is folded to define at least one backward folded portion (32) and at least one forward folded portion (33); 2) a first supporting element (31) which is arranged radially internal to said covering element and which holds said covering element in a radially stretched condition, and 3) a second supporting element (36) which is coaxially arranged around said first supporting element, said second supporting element holding said forward folded portion of the tubular elastic covering element in a radially stretched condition; b) placing said covering assembly coaxially with the elongate object and radially external thereto; c) removing said first supporting element to allow the sleeve to gradually collapse onto the elongate object, and d) removing said second supporting element to allow said backward folded portion and said forward folded portion to gradually collapse onto the elongate object.

L'invention concerne un procédé de recouvrement d'un objet allongé (11, 12), en particulier un câble électrique ou une canalisation. Le procédé de l'invention consiste à: a) former un ensemble de recouvrement (40) comprenant: 1) un élément de recouvrement élastique tubulaire (26) comportant une extrémité qui est repliée de manière qu'elle définit au moins une partie repliée vers l'arrière (32) et au moins une partie repliée vers l'avant (33); 2) un premier élément de support (31) qui est agencé radialement interne par rapport à l'élément de recouvrement précité et qui maintient l'élément de recouvrement dans un état radialement étiré; et 3) un second élément de support (36) qui est agencé coaxialement autour du premier élément de support, le second élément de support maintenant la partie repliée vers l'avant de l'élément de recouvrement élastique tubulaire dans un état radialement étiré; b) placer ledit ensemble de recouvrement coaxialement et radialement externe par rapport à l'objet allongé; c) enlever le premier élément de support afin de permettre au manchon de s'affaisser progressivement sur l'objet allongé; et d) enlever le second élément de support afin de permettre à la partie repliée vers l'arrière et à la partie repliée vers l'avant de s'affaisser progressivement sur l'objet allongé.
