ABSTRACT:
A method and device is disclosed for distributing a veil by applying low frequency sound to at least one portion of the veil, and causing the veil to deviate in its generally downward direction of travel. In its simplest embodiment, the lapping device of the present invention includes one low frequency sound generator having one resonator tube shaped for emission of low frequency sound and having an open end from which sound may be emitted to a portion of a veil. Preferably, the lapping device has two resonator tubes whose open ends are in spaced, opposing relationship, and in the preferred method low frequency sound is alternately applied at generally opposing locations near the veil, causing portions of the veil to deviate in generally alternate directions in its direction of travel.
