Process for wrapping an element with a foam layer, foam casing, tubular complex with this casing, and wreath of this complex

The sheath is applied to grip the strand, bringing its longitudinal edges (2a, 2b) together. Grip must prevent slipping relative to the strand when manipulated by an installer, in particular the sheath must remain in place when the strand is upright. The edges are joined by welding or adhesion. An I...

Beschreibung
Zusammenfassung:	The sheath is applied to grip the strand, bringing its longitudinal edges (2a, 2b) together. Grip must prevent slipping relative to the strand when manipulated by an installer, in particular the sheath must remain in place when the strand is upright. The edges are joined by welding or adhesion. An Independent claim is included for the corresponding sheath, and the tubular assembly produced. A tubular assembly (collar) with foam envelope at least 10 meters long is also claimed. Procédé pour entourer un élément cylindrique ou prismatique tel qu'une gaine (3), par une couche (2) de mousse de matière plastique, en particulier isolante thermiquement, selon lequel : on prépare une bande (2) de mousse dont la largeur (L) est sensiblement égale au périmètre de la section transversale de l'élément (3) à entourer ; on applique la bande (2), suivant sa largeur, autour de l'élément avec un serrage relatif de l'élément, en mettant en contact les bords longitudinaux (2a,2b) de la bande, et on assemble par soudage ou collage les deux bords longitudinaux (2a,2b) de la bande.
