A mold for molding fibrous molding media includes upper and lower mold bodies defining a mold cavity, the upper and lower mold bodies being movable relative to each other to close the mold. The upper and lower mold bodies have respective upper and lower mold surfaces for contacting the fibrous molding media positioned within the mold, and have gas flow openings configured to direct gases into contact with the fibrous molding media. The mold also includes a source of gas connected to the gas flow openings.

Flow through molding apparatus and method

A method for applying adhesive on a porous substrate with improved bonding between the adhesive and the substrate. The adhesive is applied on a surface of the substrate. The applied adhesive is impinged with a fluid such as air to force a first portion of the adhesive to flow and penetrate the substrate while a second portion of the adhesive remains on the surface.

Method for applying adhesive on a porous substrate

A feeder for the production of glass filaments is provided with a shallow layer of glass over the discharge wall in combination with a fluid filled cavity capable of being pressure regulated to render the operation dripless or non-dripless as desired. Preferably, the feeder is rendered non-dripless when the restart of filament formation from idled orifices is desired.

Method and apparatus for forming glass fibers

A feeder for the production of glass filaments is provided with a mechanical valve means to render the operation dripless or non-dripless as desired. Preferably, the feeder is rendered non-dripless when the restart of filament formation from idle orifices is desired.
