Abstract
An apparatus and a method for manufacturing a housing of an antipollution device including one or more bricks supported by one or more mats therein. One or more main portions are formed, the main portion of the housing defining a formed chamber in which the brick(s) compress the mat(s) between the brick(s) and the main portion to a predetermined density. One or more end portions are formed, for connection of the antipollution device in an exhaust system. When one or more transition portions are formed to connect the main portion(s) and the end portion(s), the main portion(s) is engaged by the apparatus to resist deformation of the formed chamber.
