ABSTRACT:
There is disclosed a method of making porous, vacuum formed filter tube having randomly oriented glass fibers and having at least one layer of a suitable sheet material wrapped around said porous filter tube and being in intimate contact therewith, said disclosed combination having an outer support structure of a predetermined inside diameter sufficient to compress the assembly of said porous filter tube and said sheet material when it is slipped thereover, thus providing compression from the outside to the inside and forcing the layer of sheet material into intimate contact at vertually all points with said porous filter tube.
