Provided is a dispenser for dispensing particles onto a surface comprising
a hopper for receiving particles, wherein the hopper has an opening at its
bottom, a screen having openings and located adjacent the opening of the
hopper, wherein the screen openings are uniformly sized and spaced and are
sufficiently large to let the largest particles pass through during
dispensing yet sufficiently small to hold the particles back when the
dispenser is not operating, and means, located outside of the hopper, for
moving particles from the hopper through the screen, and onto the surface.
Also provided is a method of making a web with embedded particles
comprising the sequential steps of making the web receptive to the
particles by heating, eliminating static charges present on the web,
dispensing the particles onto the web, dispersing the particles to
minimize particle clumping in the web, and embedding the dispensed
particles in the web.
