Abstract
A fin cooler particularly suited for use with a high pressure glass fiber forming bushing is disclosed. The fin cooler is structured to provide support for the tip plate of the bushing so that sag or creep of the tip plate which occurs due to the pressure and temperatures at which the tip plate operates, is substantially reduced. The fin cooler is provided with a cooling water conduit and an air distribution chamber. The cooling water serves to remove heat from the fins during operation of the bushing and that air flow from the chamber may be used to provide cooling when the bushing is shut down, or as needed during operation, the air flow maintaining the attenuating zone i.e. the tip plate and surrounding area at a desired temperature.
