Abstract
There is provided a method for filling a silencer with glass fiber, for filling an internal space between a case and an inner pipe with glass fiber in a silencer in which a porous inner pipe penetrates through a pair of through holes in the case, the method including shifting the inner pipe in a penetrating direction from a normal position where the inner pipe is secured to the case, inserting a nozzle auxiliary portion into an interior of the case from a through hole opened by the inner pipe being shifted, supplying glass fiber into the interior of the case from a nozzle of a glass fiber supply machine connected to the nozzle auxiliary portion, and filling the internal space between the case and the inner pipe with glass fiber.

A method for filling a silencer with glass fiber, for filling an internal space between a case and an inner pipe with glass fiber in a silencer in which a porous inner pipe penetrates through a pair of through holes in the case, the method comprising:
- shifting the inner pipe in a penetrating direction from a normal position where the inner pipe is secured to the case;
- inserting a nozzle auxiliary portion into an interior of the case from a through hole opened by the inner pipe being shifted;
- supplying glass fiber into the interior of the case from a nozzle of a glass fiber supply machine connected to the nozzle auxiliary portion;
- and
- filling the internal space between the case and the inner pipe with glass fiber.
An apparatus for filling a silencer with glass fiber, for filling an internal space between a case and an inner pipe with glass fiber in a silencer in which a porous inner pipe penetrates through a pair of through holes in the case, the apparatus comprising:
- a silencer support portion configured to hold the case and the inner pipe in such a state that the inner pipe is directed in an up-down direction and is shifted downwards from a normal position where the inner pipe is secured to the case to take an erected posture;
- and
- a nozzle auxiliary portion that is inserted into an interior of the case from above through a through hole opened by the inner pipe being shifted, the silencer support portion and the nozzle auxiliary portion being provided on an apparatus frame, wherein
- a nozzle of a glass fiber supply machine is connected to the nozzle auxiliary portion.
