ABSTRACT:
Prearranged ribbons of fiber leaving the front drafting roll are superimposed into layers by a composite sliver forming assembly before entering a trumpet. The composite sliver forming assembly consists of tubular guides extending at an angle from the front drafting roller to the trumpet entrance. The tubes are designed with a flat bottom to support the sliver, allowing for overlapping at the tube exit, and to achieve an exact ribbon exit 90.degree. downward into the trumpet entrance where the layered ribbons are combined into a composite sliver.
