Beschreibung
Zusammenfassung:An exhaust treatment unit including a longitudinal core around an axis, a support mat, and powdered insulation impregnated between first and second layers of the support mat. !n assembly, the mat is first wrapped around the core once, and powdered insulation is applied to the surface of the unwrapped portion of the mat prior to further winding whereby powdered insulation is disposed between mat layers after further winding. La présente invention concerne une unité de traitement de gaz d'échappement comprenant une partie centrale longitudinale disposée autour d'un axe, une natte de support, et un isolant en poudre imprégné entre la première et la seconde couche de la natte de support. Lors de l'assemblage, la natte est tout d'abord enroulée une première fois autour de la partie centrale, après quoi l'isolant en poudre est appliqué sur la surface non recouverte de la natte avant de poursuivre l'enroulement de cette dernière afin d'emprisonner l'isolant en poudre entre les deux couches enroulées de la natte.
