rotation 12 and is driven by shaft 14 the spinner is supplied by molten stream of glass 16 which is centrifuged through the walls of the spinner of form glass fibers 18 the glass fibers are maintained in a soft attenuable state immediately outside the spinner by the heat from annular burner 20 the radially traveling glass fibers are turned down by blower 21 into a cylindrically shaped veil 22 of fibers traveling downwardly i e in the direction of the axis of the spinner the process for creating the downwardly moving veil of glass fibers is well known in the art positioned beneath the glass spinner is a rotatable device for distributing polymeric material into contact with the veil from a position within the veil the embodiment shown in fig1 includes the use of a second spinner polymer spinner 24 for distributing polymeric material into contact with the veil the polymer spinner can be mounted for rotation in any form as shown it can be mounted with supports 26 into direct contact with the glass spinner for rotation the polymer spinner is supplied with stream 28 of molten polymer material as shown this stream can be feed through the hollow portion of the glass spinner shaft the molten polymer can be produced or supplied by using extruder equipment commonly known to those in the art of polymeric materials such as pet depending on the viscosities surface tension and other parameters of the polymeric material and on the rotation rate and orifices of the polymer spinner polymer fibers 30 may be produced from the polymer spinner the polymer fibers travel radially outwardly where they meet and intermingle with the mineral fibers since the glass fibers and glass spinners operate.
