ABSTRACT OF THE DISCLOSURE A fiber distribution and depositing apparatus includ- ing a forming bell including front and back walls converging and concavely curved in the direction of flow, and side walls connected to the front and back walls to define an open-ended passageway for fluid-entrained fibers leading from an inlet to an outlet end, said side walls diverging along straight lines in the direction of flow, the cross-sectional area of the passageway along the length thereof remaining substantially constant. The forming bell is disposed between a fiber transport means for directing gaseously-entrained fibers into the bell former inlet at a high velocity and a forming surface positioned adjacent to the outlet of the forming bell and movable along a predetermined direction of movement for receiving the fibers passing through the forming bell passageway.
