    摘要: A process for installing a fiber wrap or a packing material in a tubular construction, for example a muffler assembly, includes a step of compressing a mat of packing material by removing at least a portion of air from the mat of packing material. The mat is oriented against a tubular wall. After the step of orienting the mat, a shell, such as a muffler shell, is oriented over and against the mat. The step of compressing a mat may include drawing a partial vacuum through a perforated tubular wall, where the perforated tubular wall is the tubular wall that the mat is oriented against. Alternatively, the step of compressing a mat may include drawing a partial vacuum through the perforated wand inserted into the mat. Apparatus for installing the packing material can include a mandrel, a pump apparatus, and a sealing arrangement; or, the apparatus can include a wand and a vacuum pump.
