Abstract: A process is provided for filling a muffler shell with fibrous material. The process comprises the steps of: providing a muffler shell comprising first and second muffler shell outer parts which define an internal cavity when coupled together and an internal structure adapted to extend at least part way through the shell internal cavity for defining at least one channel having one or more openings communicating with the shell internal cavity; placing a form over at least one of the internal structure and the first muffler shell part; drawing a partial vacuum through a first end of the channel; feeding fibrous material into the form while drawing a partial vacuum through the channel; removing the form after the fibrous material feeding step; and positioning the second muffler shell part over at least one of the internal structure and the first muffler shell part.

Abstract: A method for forming continuous glass fibers is provided comprising the steps of supplying a plurality of streams of molten glass from a bushing, drawing the streams into continuous filaments, passing a stream of air across the continuous filaments in a direction of between approximately 20.degree.-30.degree. below horizontal to cool the continuous filaments, thereafter, applying a sizing material to the cooled continuous filaments and collecting the continuous filaments on a spindle or collet.

Abstract: Chrome-free aqueous size compositions containing quanternary salts reduce fuzz and fly in glass fiber gun roving. The roving particularly achieves a desirable ease and completeness of chopping in conventional chopping and spraying equipment for molding operations.
