ABSTRACT:
Apparatus for making a fiber bed element made up of a roving of fibers axially packed in the annulus formed by a pair of concentric screens, wherein structure is provided for holding and rotating the screens in a concentric positioning on the lowermost of a pair of vertically aligned platforms. A roving of staple fibers is fed into the annulus through a tube supported by the upper platform and a packing mechanism mounted on the upper platform packs the roving as it is fed into the annulus. The lower platform is moved downward as the roving is fed into the annulus, in order to maintain a uniform packing force.
Downward movement of the lower platform is controlled by a control system which senses packing force and moves the lower platform downward in response to this packing force to maintain a uniform packing density.
