Abstract:
Apparatus for forming fibrous filter media comprising:a fiber media forming means having a plurality of spaced die sets, each set including a plurality of spaced aligned apertures arranged to dispense fibrous strands therefrom in heated mat layer form;a mat forming collector means having a contoured surface positioned in relatively movable spaced relation below said fiber media forming means to successively receive each heated mat layer from each die set of said fiber media forming means to preselectively contour shape stacked mat layers into a conformed contour-shaped filter mat successively received from said fiber media forming means; and,a first transfer means cooperatively positioned with respect to said mat forming collector means to receive the conformed contour-shaped filter mat therefrom to transfer said conformed contour-shaped filter mat to a second transfer means for further contour shaping at preselected differing speeds and along differing contoured surfaces from said first transfer means to preselectively vary the shape of said conformed contour-shaped filter mat into a finalized contour-shaped filter mat.
